Those struggling next to allelopathic plans are peas, beans, tomatoes, lettuce (next to brassicas, sunflower, fennel). Mildly allelopathic - onion (for peas and beans), dill (carrot), tomatoes and corn are best kept separate to avoid pests. Tomatoes and potatoes should be kept separate to avoid potato blight fungus, potatoes and cucumbers (aphids and cucumber beetles). Competing for the same nutrients - brassicas and strawberries, potatoes and melons.
All these years i thought i'd failed as a gardener. Turns out ALL the fennel has been murdering all my tomatoes and beans. Thank you for restoring a bit of my self-esteem whilst giving me a huge project to tackle
I have been working with companion planting for 15 years. With a walnut tree, I have to grow all my nightshades in raised beds or giant pots. My walnut leaves and husks are collected for city compost, rather than let them dominate my own compost. I grow my fennel 3 plants to a 4-5 gal. pot AWAY from carrots and dill.
To be fair not knowing what’s good to grow together is failing. But that’s just a part of learning. And we should embrace failing and learn from what we did wrong
@@breakdown2878 Its best to do it right if you don't do the right thing it could be expensive or time-consuming. Secondly, it could be deadly too. Best to ask questions before planting or growing things eg do not put a lemon tree near an orange tree. Sometimes you need to plant two things near each other to pollinate etc.
@@theresekirkpatrick3337Some pests can be confused by plant scents. You may want to check into that. By recollection, marigolds and radishes are on that list.
I had a small area where the house I was renting had a boxed off area filled with gravel where the rain trough from my house and the neighbours drained into. While cleaning up the neglected yard, I found the remains of an old garden, including some old rhubarb rhizomes. I put them in a tub of water and was surprised to find that they started growing again! Since they weren't dead, I decided to get rid of the gravel and give them that well watered corner. I hate weeding, so I planted chocolate mint around them. Before I knew it, my little 2' by 5' planter box was full and the effect of the giant rhubarb leaves with the mint filling in the spaces was beautiful. I only had to weed once and never again..
I have planted tomatoes and bell peppers in the same container. Neither one did well all season. I planted the same type of tomatoes and peppers in separate containers the same season and both did well. Thank you for teaching this info. from your own experience.
The plants in my garden totally missed this memo. I have many allelopathic plants growing next to other plants. Each bed is different, though many have at least one perennial herb, and I scatter annual herbs around for green mulch. All of my tomatoes went into beds that still had garlic ripening. I am wintering them with peas now. I do my best to rotate crops and replenish organic matter. One raised bed currently has bunching onions, calendula, bronze fennel, wildwood basil, sunflowers, parsley, pink dandelion... It's a party 🥳
Yeah, most allelopathy is a very smal effect. The most important part is controlling for light. A big bank of sunflowers can be surpressive, but I have zero issues mixing them into the garden.
So much gardening "lore" is untested and pure hogwash. Some of the problems are because the two plants have different watering requirements. Others are because the roots of one are wide spread and sucking up the water the other one needs.
@@HoboGardenerBen Yep. Most of this video is kind of overblown, honestly. I've grown pole beans running right up sunflower stalks, both direct-seeded at the same time. No problems. I've grown corn right next to a black walnut tree just to see what would happen - the corn grew and produced normally. I've also been interplanting garlic and onions among tomatoes for years; they both do just fine. Bear in mind I transplant tomato seedlings into those beds, I don't direct seed them. In many cases allelopathy mostly affects seed germination, so you can get around it by putting in starts instead.
Confirmed from experience: brassicas are death to strawberries and vice-versa! + I once had an old walnut tree and you could trace the roots by the effect on veg growth + cucumbers are death to potatoes. And I learned a few more from your video, thanks!
15 years ago, I tried to plant a garden under a black walnut tree. The only thing that grew under my walnut tree was raspberries! They didn't seem to be bothered by the secretions dropping from the walnut leaves and they actually thrived. So, my garden went elsewhere, and I had a large raspberry patch!
Ha! I was gone from my garden for 3 months this summer (on an automatic watering system, and had a friend check on it periodically) but couldn't figure out why my greens hadn't grown to jungle size....the bed was FULL of sunflowers from last year! Thanks for this information. It will be a great help for next year's garden.

No, it doesn't. You probably have a lot to learn about basic soil building. Focus on the soil, build it slowly with mulch and photosynthesizing plants and it will grow healthy plants. Most of this video is simply not true, a bunch of myths that get spread around without people testing them out first. Elaine Ingram is a good place tonstart for learning about soil. One Yard Revolution made a bunch of excellent videos, including a series tesdting out gardening myths, most are false. Charles Dowding and Edible Acres channels are both great for expanding your understanding. The book Gaia's Garden by Toby Hemmenway is a good intro to permaculture at the home-scale. I've personally learned the most from years of watching Edible Acres and lots and lots of dirt time. Once you understand how to build soil, the rest is super easy.
My last garden was set on a concrete slab that used to have a shed on it. I used cinder blocks arranged 2, 3 , 4 and 5 layers from front to back arranged in four rows for access and filled the cavities of them with soil.(The last two rows had their bottom fourth brick turnred sideways making them only three deep). None were cemented only stacked in overlapping groups. all varieties grew well having their own "pot" to grow in. At harvest I merely unstack them and rearrange in new ways. Just not much room in the yard, and our soil in Tucson's foothills has too many minerals (and wild burrowing animals) to grow anything even with a raised bed over it. I did not know this trait about sunflowers...Thanks!
Past owners planted a walnut tree in the vege garden. Every part of it contains juglone. We raise our vege beds to get round it, but sooner or later the juglone creeps in, and suddenly everything wilts.
Try using giant pots or stock watering tubs over a layer of bricks to prevent rooting into contaminated souls. I layer the bottom of my pots and tubs with a couple inches of volcanic pumice 1-2" gravel for a similar effect. The only tomatoes and peppers which have suffered were those that volunteered in the walnut zone. Take heart; many NA native flowers di very, very well near walnuts, PROVIDED THEY GET ENOUGH WATER. If you want a reliable ground cover for dry, deep shade, lilies of the valley will serve.
You can look for lists of juglone tolerant plants. Most are natives of eastern North America (ie they have coevolved with Juglans nigra, which is probably the highest producer of juglone) and are not the typical/conventional garden vegetables called for in most recipes. However, some *are* edible, and thus you can create new recipes by experimentation. Maybe there are cookbooks developed by the Cherokee and other literate Natives?
@@sepulkariy Not all. Many plants (some of which I personally consider to be weeds, like Kentucky bluegrass, Poa pratensis) are immune to juglone and thrive under walnut.
@@christal2641 I know it's just a typo, but reading about contaminated souls, nonetheless on halloween, has its own special value 😆 Under my walnut tree grows some grass and nettles. A very poor rhubarb (I knew of bad influence of juglon, should have replanted it) and long, long ago my mum tried growing asparagus between two walnut trees. It survived just fine for few years, but needed much care and when the attention was redirected elsewhere, it just vanished.
Here in the US, Black Walnut Trees are famous for suppression anywhere near their roots and even the fallen leaves. The suppression lasts even after removal in the soil for years.
Each state Extension You state Extension Dept. publishes lists of plants that thrive or suffer near walnut trees. Several factors should be considered. Most Juglone is generated by the roots, and decays over a 20 YEAR period.The most damaged areas will be under the dripline of the tree. Over the century, our tree's canopy has been reduced by half due to construction next door, and a tornado, so I can only guess at the original dripline. If you quickly rake up AND REMOVE all the FALLEN nuts, HULLS, leaves and buds from the tree, the accumulated effect of Juglone will be bydiminished.
Great video, thanks! Black walnuts, buckthorn, and creeping Charley will kill susceptible plants around them. On his list are fennel, sunflowers, decaying radishes greens, mint, garlic, onions, mint
I have a feeling you forgot to mention mint 😆 I don't think my mint kills a lot of stuff (I still need to deweed it!), but sure enough she's creeping like crazy, I knew that and should keep it in the pot, but I love mint and previous one was killed by weeds (spearmint), so when I got peppermint which I love the most, I didn't want risk it to be killed by weeds as well
I have creeping Charlie everywhere in my wildflower perennial native garden yard in the suburbs of Minnesota and it's beautiful, blooms and haven't seen any suppression of my unwatered wood chip mulch constantly blooming garden, can you point to a study that shows that creeping Charlie has allopathic tendencies? Thanks
I have noticed that about sunflowers. My veggies that are planted near them, try to grow in a direction that is furthest away from the sunflowers! I think if the veggies and other plants could dig themselves out and move...they would. 😂 Now I know.
I learned this the hard way about sunflowers. 🌻 I added them to my veggie garden this summer. They have been growing for years in the very corner of my property to the point that my house is known as the sunflower house in my neighborhood. People would pick them and it made me crazy. So I planted them near the tomatoes and peppers in a more protected spot. They looked great but, my vegetables suffered. Will try better next summer. 😬 Always learning, every summer!
I used to have a couple of grape vines. for the first few years any grapes we got from them were tiny and not worth harvesting. Finally on the fourth year we got a couple of nice bunches of grapes from each vine. Fifth year we had about half a dozen decent bunches from each vine. This was about the time we planted sunflowers alongside them to fill the space in that bed. This was also the last we saw of any decent bunches of grapes. The vines still got bigger over the years but they simply never produced much in the way of fruit. I wonder now if the sunflowers were to blame. By the time I moved out of that house those vines were pretty impressive but I simply abandoned them as they seemed like a lost cause. The sunflowers came back every year without fail.
You are so right about the black walnut. My new neighbour two doors down from me has a very tall black walnut tree in her backyard. I gave her some hard neck garlic cloves to plant in her garden. The same garlic that grows very well in my garden. I even gave her some bone meal to mix into the planting holes. Not a single garlic grew in her garden. I wonder, is it the roots of the black walnut that poison the ground and therefore didn't give the garlic a chance to grow? Or is it the leaves that covered the ground in the Fall, right after the garlic was planted? The previous resident told me that she would love to grow veggies in the back of her garden but nothing ever grew there.
Sounds like a good place for wicking beds with a sealant under them - concrete or plastic according to preference - the same as people who want to grow vegetables but find their soil is full of arsenic or other heavy metals. Soil full of walnut isn't poisonous to humans, but if it's killing their vegetables that's still something to seal out.
I'm not a gardener because everything I plant suffers and dies! I really try to be good to them, but ignorance is deadly. THANK YOU for such GOOD advice. I subscribed because such advice is GOLDEN if you want to grow things! Guess what! I planted a tomato plant twenty feet from a walnut tree and it had a nice tomato on it when a walnut (apparently) fell on it and knocked it off! That same tree actually hit me on the head with a walnut! I did you not!
this explains why one of my Moringa trees didn't do well last year and looks amazing today. Fennel! i planted fennel with it! This video explains so much of my failures and issues. THANKS!
The cucumbers and beans should be fine. Ultimately planting stuff with risk is better than not planting at all. I do it all the time when space is an issue But if you run into problems with those pests you know why 💁
@@CulinaryGarden1 🤔😄😄.if he missed something add , what he missed 🤔🤔😄. It’s same list as other supplied . Maybe you heard things that aren’t in the vid .😄😄 or supplied the .. main ones 👻👻👻
Here in the States, New Mexico, to be a bit more precise, we have mostly the same problems. My favorite plants to plant near each other are tomatoes, Basil, summer and zucchini squash and chili peppers. My friends used to call it my Italian sauce garden. 🍅🌶️🥒🍝
I know about biodynamics that says which plants fight other plants (or each other), which are neutral and which help other plants / each other. My parents have a book on this, but I didn't read it, just the table with influences. It's not new concept, but I agree with you, this isn't talked about on gardening channels, I don't look for gardening channels, not subscribed to any of them, but sometimes they find me 😂 and if you tap one video, yt shows you more and they can have interesting titles, too, so somehow you end up watching them, even if you don't do gardening personally.
I'm mostly appreciating the fact that he's actually bothering to go into some of the nuances and is more accurate than most of the claims I've seen which honestly seem to be superstitious more than scientific. There's absolutely scientific understanding of this and that's what he's presenting here, but I have seen so much more of the BS on the internet that it's nice to see somebody grounded in reality😅
Something that might help…a garden map, illustrating what plants should go where, according to allopathic tendencies, and what plants favor their neighbors…just a thought…from an old vet, retired in the foothills of the Smokies.
We put peppermint plants in a bed some ten years ago. Everyone told us we’re crazy for the reasons you mentioned in the video. They were all dead within a year… the mint, I mean… other things grow perfectly fine in that bed…
Good warning about mints. Apple mint is a legit titan of the garden. Not allelopathic, plenty of plants mix with it, but the tall shoots block the light for other plants. That's the easiest way to prevent issues between plants, place them appropriately for getting the light they need during their entire growth cycle. Chop\drop to open some light will give the struggling plant a leg up. Only plant I have seen actual surpression from is black walnut trees, only some stuff will grow by them. Still a lot of good choices, some stuff isn't bothered by anything, like winter squash and indeterminate cherry tomatoes. Vines are strong in a general sense. Being able to root in as they crawl along is a huge advantage. My volunteer untrellised tomato vines always look stronger and healtier than the trellised and pruned ones. Makes sense, only one rooting area for the plant and it is being constantly wounded by the pruning, opening it up to infections.
I knew about most of them but not sunflowers! Makes perfect sense though, I think they were the downfall of my bed this year, I'd not grown them before. Great video, thanks!
Allelopathic, I think. Many moons ago, I was taught about how many eucalypts are allelopathic. I had no idea about these veggies, though. I once read a companion planting book that encouraged planting garlic amongst your veggies. Thanks for this information. I'm in the process of planting some veggies, so this was a timely video.
@@carolannhartley359 KOALAS are not so sweet as they look. Let's just say that every plant has its own constellation of talents/gifts to share and needs. There's a good role and good partner/s for everyone, but not every role or partner will be good for you.
@@christal2641 Yes, in a horticulture class, our teacher said that all trees have their pros and cons, so you just have to research and find ones that have traits you can live with when you're planning to add them to your yard or garden.
I have a Common Walnut which used to cover half of my garden (80’) ive pruned it back since moving in and chopped and dropped the prunings and composted them, the only reduction in growth was due to sunlight lost which is no longer a problem, I believe it is Black Walnut that produces Jugilone not so much with the common walnut.
Now I know why pole beans did so poorly two seasons in a row. I planted two sunflowers next to them🤯 I also had zinnias next to the sunflowers and they were just horrible. Thanks so much for such a good instructional video!
I’m green with envy. You had a guava. I’m considering getting rid of mine. Healthy when I bought it three years ago, sick ever since! In the hope of perking it up I transplanted it into large pot. Still sick 🤮
@juneshannon8074 the biggest thing I've found with the guava is that whilst young they really don't handle aussie sun. I have mine up against a fence on the eastern side of property, lush soil mix of manures and potash, it permanently has a fruit fly net draped over it during summer and spring. It's only been there a year so not big enough to fruit yet
I am curious, I have to grow hydroponically (have just started) and wonder how much of this applies to this method of growing. Is the surpression done by the root system (which would not effect me as each group of plants is in its own reservoir) or is there something in the air (as it were) that effects nearby plants?
Yeah chemicals released through roots. Although moisture levels and soil composition are the two biggest factors on how strong the effect can be. So I have no idea if growing in hydroponics would enhance or nullify the effect 🤷
@@CulinaryGarden1 I shall soon find out, I am guessing that the effect will not be as noticable as the only other plants that each root will be heir own kind. I am curious though if there is an opposite to this effect (in soil obviously) where have the root system of two different plants is actually beneficial, more than keeping pests or certain insect away from the plants that is?
I am a hydroponic and soil gardener too: the suppressive effect is reduced from the roots. If you have a separate reservoir for each crop as you describe, it will be fine. On the other hand, if you have a shared reservoir recirculating on many crops like me, it will go through the lot regardless of physical proximity ...
So, can I grow mustard spinach with other brassicas? We live in a very hot climate so now is the time to plant brassicas. Also, I learned a bit about garlic last spring when I planted it with grapevine. The grape barely survived.
Awesome video, so much info. Many thanks. I only plant store bought organic potatoes and they grow very successfully. Just about to plant a whole load of sweetcorn and will put peanuts underneath those. Should be good up here in central Qld. Blessings to Humanity We Rise
Sunflowers suppressed bean seeds and a few other plants in their proximity. What I found is that once a plant is established, like a biannual, it does ok the second year because it has a headstart on the sunflower seeds.
U.S. Virginia, Zone 7. I love peas, tomatoes, peppers, eggplants, basil and other herbs, beets, and many others. I once planted fennel and now HATE it. I'm constantly working to pull out the volunteers. NEVER, NEVER, NEVER plant Jerusalem artichoke (sun chokes). They are super aggressive and super persistent. I planted a small pot full and they quickly filled a 2x3 meter raised bed. They also sent runners under the bed borders, and I've dug the whole area out three years in a row. I'm crossing my fingers that I've gotten most of it out.
Another reason why farmer plant sunflowers along the perimeters is because they tend to attract the kind of birds that eat insects, that eat the crops.
Good video I didn't know about the sunflower thing but it makes sense because over the last couple years my flower garden has been overtaken by sunflowers and now that's all I have. Interesting thing to mention I live in a big potato production area and after we harvest the potatoes we plant these long white radishes they only grow for maybe a month and then it gets too cold and they die but it keeps out the weeds for next year and it's a good nematode suppressor we grow russets and nematodes can be a big problem good natural pest control
I do garden design, installation and maintenance, and I have often enough been asked by clients why some part of their garden is not looking happy. Many times it is a bird feeder - sometimes with just sunflower seeds or a bird-seed mix containing sunflower seeds - most bird-seed mixes in the U.S. have them. Black oil-seed sunflowers are the worst culprits. I am not always able to find a different location for the feeder that suits the client, nor to persuade them to use a mix without sunflower seeds or a mix with hulled sunflower seeds. (Those mixes are more expensive.) The issue seems to be the hulls, not the seeds themselves - the birds eat the seeds and drop the hulls. (The hulls can also be an irritating mess to clean up, depending on the location of the feeder.)
Perhaps they are spraying the sunflower seeds like they spray grain, to desiccate them. Glyphosate residue can be composted out if given ideal conditions, or time.
@@Jbomb312 I think the seeds in question were falling from her own sunflower trees. I paid down a rubber ring under my bird feeder to reduce sprouting, but I am STILL killing dozens of morning glory seedlings there 5 years after I last stocked that feeder.
@@christal2641 I was replying on jhourlet's comment about the shells poisoning the soil, and yes sunflowers can be allelopathic but the real poison is glyphosate which is used in commercial grain production. It's much more damaging than the shells themselves.
I hadn't known that about radishes. Good to know! I also have peppermint in my lettuce & kale bed, but so far they all seem to get along. I don't mind if the mint takes over and wins out -- it's my favourite thing in the garden.
Great video, just discovered your channel thanks. After watching this, i have a something to pique your interest on a video topic, on the common thought about 'nitrogen fixers', in the way that you mentioned their benefits. I was down a youtube rabbit hole on legumes and it was suggested that if you let the legume go to bean, they use up that nitrogen, therefore they only add to soil as a cover crop.
Thank you for the education about these plants and how to be successful at growing a vegetable garden. Im a novice, and this information is so helpful!
I love informative videos like this and this is one that I have never heard before which is great. Many of the garden channels, which I love, do a lot of the same content. Refreshing and informative
I have been making this mistake (planting sunflowers, garlic, mustard greens and mint) every year and yes I have beautiful sunflowers but terrible harvests on everything else nearby. Thanks for helping me identify the problem.
Oh my gosh, there is SO MUCH I didn't know!!! The only thing I knew in your video was walnut trees. I wonder if mint is why my blackberries died there but did so well elsewhere. I'll need to watch this again with a pad and pen. Thank you.
Can you make a video of what we should plant next to each other? and if we are doing rows with 30 inch rows and 15-18 inch walk ways how will this work?
Can vouch for gum trees being allelopathic. We have huge gums on a reserve just the other side of our back fence and their roots invade everything even flower pots. I'm sure their roots and dropped leaves exude growth supressing compounds into the soil. Then there's the physical damage from a constant barrage of twigs and gum nuts which perforate leafy vegetable plants. Having said all that I am currently growing quite successfully directly under their canopy in wicking beds. My growing soil is completely serparated from the earth soil, it's the only way.
I love the starter friendly presentation of this information. Plus with the titles for future investigations for me too. You grow a lot more then I do but still great information to help me getting started
I love your videos & I really appreciate content from an Australian gardener as a fellow Aussie! I paused the video and ran outside as soon as you said sunflowers because I have a little bed with cucamelons, tomatoes and sunflower and strangely noticed not long after planting the sunflower in there the cucamelon vine slowed down and before that it was growing rapidly. Would you move the tomato plant if it’s only young and not have it next to the cucamelon?
If it's already there & established, i personally would just roll the dice for this season. But i also grow lots of stuff so if i have a handful of failures i don't care to much
Do leaves from these plants cause problems with compost, especially radish leaves. I put some into my compost heap yesterday. Great video, so much to think about and take on board, I am hoping to grow fennel in my back garden next year, so now I know I will have to do it somewhere else. Are large planters any good for that, I have limited space, so use a lot of large containers. Many thanks again. Jane I posted this a few days ago and it has ended up near the bottom of the list, so I have re posted it. I hope that you dont mind.
Because each type of plant wants to survive. There are plants that will grow terrifically well together. The Navajo have grown beans corn and squash together - they call it the three sisters.
The juglone exuded by black walnut trees does not affect corn. I grew a block of corn directly next to a black walnut and it did just fine. Paw Paws are also juglone resistant, as well as a number of other plants. Including some vegetables. It's not like nothing *ever* grows near walnut trees... look at a forest some time. ;)
Yeah but you can say that about all the plants on this list. It's never a plant suppresses the growth of all other plants, it's more this plant impacts these other plants in this way under these circumstances. Black walnut however is definitely one of the most aggressive plants in nature that people regularly encounter however nothing can hold a candle to conifers. Those things know how to monopolize realestate😂. I'm kind of surprised he left them out well including Black Walnut because usually they're part of the same conversation along with a few other trees kind of going through the gradient of how much do they have with the plants around them😅. It's kind of cool because in natural forests those iconic trees change everything about the ecology in their war on other plants.
I learned pretty quick that some plants just do not like sunflowers. pmuch any cucurbit crawls away from them and others sort of grow very weak. Might be my last year of growing sunflowers as they suppress other plants and I don't even get to use the seeds because birds get to 'em
Also I saved the link so I can watch this again. Good to see an Aussie take on this, because most content about companion planting is US or UK based and not entirely relevant here.
Nasturtium can be very aggressive. I had it next to a young Kiwi plant, and the Kiwi was growing really poorly. Now I have some other flowers there, and the Kiwi is doing much better. I love Nasturtium in the garden because if flowers all year and you can use all parts of it as spice or food decoration.
I planted nasturtiums at the ends of my 12ft long raised strawberry bed for the first, and last time, this year. The plant turned into a flowering thug! Smothered a 3 x 4 patch of strawberry plants and deposited a few million seed pods which I have been hand picking out of the bed for the past 2 days. I threw the seeds into the abandoned field behind our home.
Here in Minnesota, I use Moonflowers and nasturtiums because their seeds are not hardy over our winters, so no jungle of strays. I do save there seeds -- indoors. Our native morning glories try to pull down my dwarf fruit trees.
@@wrongwayconwaythey're basically a weed in my community garden and every time somebody shows me one I'm like oh that's weird I'm not sure wait no I think I know what that is it's another color of it.

Excellant video. Thank you for moving around your garden while you recorded. I love seeing new layouts and how to add more garden space. Question: are your raised beds filled with dirt/compost?
Raspberries are my favorite. Wow I am surprised at how badly my garden has been arranged because of other people planting things where they shouldn't be. My sister put Tomatoes next to my Glass Corn, Acorn squash, Grapes, Raspberries and Butternut squash. I planted Apple mint along the edge of my long garden bed with a 30cm gap between them and everything else in hopes of creating a defensive barrier to pests. I don't know if it was helpful. My sister also planted Jerusalem Sun chokes with Russet potatoes and the Sun chokes seem to have killed the potatoes.

I have some fennel growing right next to a wattle, the wattle is booming. Will fennel get rid of couch grass. Maybe sunflower would get rid of couch. Maybe I can throw raddishs on the couch. Going to have to grow some wormwood I think
Lavender (not a vegetable) in my experience is extremely allelopathic (I just learnt this word thanks to this clip). But yes I have planted lavender to bring in the pollinators only to realise over time that they should have their own allocated bed 🙂.
Guh… I intentionally planted garlic and onions in the same bed as my brassica seeds thinking they would keep pests away. Everything is growing so slowly - lesson learned!

Great information. I grew potatoes and garlic together, and they were very happy.. I got a really good crop out to both of them. I learned something from your. Thank you. New subscriber.
I just eat the wild strawberries in my yard instead of growing them. I actually do but in all seriousness, I use grow bags in my garden. It tends to isolate any soil fungus and I’ve had success using them. I’ve also grown heirloom tomatoes and heirloom cucumbers close to each other with no ill effects. I grow manalucie tomatoes and white wonder cucumbers. They are heirlooms today but they are what my grandmother grew. The tomatoes love 90F days so they grow well here in the American South. The white wonder cucumbers are a little milder than the store bought here and are good in salads.
I’ve never had that issue with sunflowers, I grow them every year in my cut flower patch in my garden along with plenty of other flowers - cosmos, dahlias, zinnias etc
I think it's mostly because they suck up so much nutrients. If your soil is really good it might not matter at all. I grow my tomatoes and sunflowers together, never had an issue. But I also have rich compost that I put down every single year.
I use sunflower to wipe out weed patches. Grow a dense grove of sunflowers, clear it out, it's as if nothing was ever there. Never thought about it being a problem in isolated cases. Maybe I should.
Excellent information as I didn't know this. Being new to gardening, can you grow the plants that kill others together in the same raised bed. Like cabbage, broccoli, cauliflower & cucumbers? ❤ your channel & garden. Hope mine will look like that next year.
Grew massive amounts of fennel, on the sides of my cabbage, wombok, and cauliflower beds, also grew heaps of beetroot with daikon radishes grown in the same beds.....
This is amazing information, thank you for this video! Would it be good to use allelopathic plants to suppress the growth of weeds around the garden? I have certain areas of my garden that I'm still planning what to do with, yet they are constantly a nuisance with the amount of weeds that pop up there.
This was super helpful, thank you! I’m in Sydney and have been enjoying your seasonally-appropriate content :) I have some cabbage in the same bed as a couple of strawberry plants, although not immediately adjacent… the cabbage are just seedlings still, maybe I should relocate them 🤔

Thank you kind soul
❤ indeed a big thank you❤
Those struggling next to allelopathic plans are peas, beans, tomatoes, lettuce (next to brassicas, sunflower, fennel).
Mildly allelopathic - onion (for peas and beans), dill (carrot), tomatoes and corn are best kept separate to avoid pests. Tomatoes and potatoes should be kept separate to avoid potato blight fungus, potatoes and cucumbers (aphids and cucumber beetles).
Competing for the same nutrients - brassicas and strawberries, potatoes and melons.
@@ShrenikBhurathank you!! This is very helpful❤
Black Walnut trees are very toxic to horses and geese. Do not use sawdust or chipped wood as bedding it you will kill these animals!!
All these years i thought i'd failed as a gardener. Turns out ALL the fennel has been murdering all my tomatoes and beans. Thank you for restoring a bit of my self-esteem whilst giving me a huge project to tackle
I have been working with companion planting for 15 years. With a walnut tree, I have to grow all my nightshades in raised beds or giant pots. My walnut leaves and husks are collected for city compost, rather than let them dominate my own compost. I grow my fennel 3 plants to a 4-5 gal. pot AWAY from carrots and dill.
Fennel should have their own pot or area. Ask Italians they will tell you. lol
That would be so traumatic! It's good to know.
To be fair not knowing what’s good to grow together is failing. But that’s just a part of learning. And we should embrace failing and learn from what we did wrong
@@breakdown2878 Its best to do it right if you don't do the right thing it could be expensive or time-consuming. Secondly, it could be deadly too. Best to ask questions before planting or growing things eg do not put a lemon tree near an orange tree. Sometimes you need to plant two things near each other to pollinate etc.
Farmmers around here plant borders of sunflowers around their fields to stop invasive weeds from encroaching, especially from banks and ditches.
I’ve seen this is South Dakota, the farmers say it works well.
I had to pull my sunflowers they got infested with aphids early summer
good to know!
Thanks for I plant my next sunflower this season
@@theresekirkpatrick3337Some pests can be confused by plant scents. You may want to check into that. By recollection, marigolds and radishes are on that list.
I had a small area where the house I was renting had a boxed off area filled with gravel where the rain trough from my house and the neighbours drained into. While cleaning up the neglected yard, I found the remains of an old garden, including some old rhubarb rhizomes. I put them in a tub of water and was surprised to find that they started growing again!
Since they weren't dead, I decided to get rid of the gravel and give them that well watered corner. I hate weeding, so I planted chocolate mint around them. Before I knew it, my little 2' by 5' planter box was full and the effect of the giant rhubarb leaves with the mint filling in the spaces was beautiful. I only had to weed once and never again..
I have planted tomatoes and bell peppers in the same container. Neither one did well all season. I planted the same type of tomatoes and peppers in separate containers the same season and both did well. Thank you for teaching this info. from your own experience.
The plants in my garden totally missed this memo. I have many allelopathic plants growing next to other plants. Each bed is different, though many have at least one perennial herb, and I scatter annual herbs around for green mulch. All of my tomatoes went into beds that still had garlic ripening. I am wintering them with peas now. I do my best to rotate crops and replenish organic matter. One raised bed currently has bunching onions, calendula, bronze fennel, wildwood basil, sunflowers, parsley, pink dandelion... It's a party 🥳
Thanks. I want to grow fennel.
Wow!
Yeah, most allelopathy is a very smal
effect. The most important part is controlling for light. A big bank of sunflowers can be surpressive, but I have zero issues mixing them into the garden.
So much gardening "lore" is untested and pure hogwash.
Some of the problems are because the two plants have different watering requirements. Others are because the roots of one are wide spread and sucking up the water the other one needs.
@@HoboGardenerBen Yep. Most of this video is kind of overblown, honestly. I've grown pole beans running right up sunflower stalks, both direct-seeded at the same time. No problems. I've grown corn right next to a black walnut tree just to see what would happen - the corn grew and produced normally.
I've also been interplanting garlic and onions among tomatoes for years; they both do just fine. Bear in mind I transplant tomato seedlings into those beds, I don't direct seed them.
In many cases allelopathy mostly affects seed germination, so you can get around it by putting in starts instead.
Confirmed from experience: brassicas are death to strawberries and vice-versa! + I once had an old walnut tree and you could trace the roots by the effect on veg growth + cucumbers are death to potatoes. And I learned a few more from your video, thanks!
Wow. I never would have imagined the effect one plant would have on another. Thanks for sharing your experience.
Black walnut will kill stuff.
15 years ago, I tried to plant a garden under a black walnut tree. The only thing that grew under my walnut tree was raspberries! They didn't seem to be bothered by the secretions dropping from the walnut leaves and they actually thrived. So, my garden went elsewhere, and I had a large raspberry patch!
Yeah it's funny I see raspberries growing under walnuts all the time.
Raspberries like really acidic soil so that may be why.
Ha! I was gone from my garden for 3 months this summer (on an automatic watering system, and had a friend check on it periodically) but couldn't figure out why my greens hadn't grown to jungle size....the bed was FULL of sunflowers from last year! Thanks for this information. It will be a great help for next year's garden.
Pumpkins are fine to run underneath sunflowers 🌻
@@justinarnold7725 beans too
I use sunflowers to clean the soil from toxins.
Plenty of crops have no trouble being near them as long as they aren't being shaded
Mesoamerican indian trinity,
Corn, beans, squash/melons
Corn gives structure for beans to climb on squash/pumpkin/melon, good ground cover
all three in a smaller area.
I hope you're correct. I've got pumpkins growing near my sunflowers. So far, they are both growing well.
Oh my gosh I've been gardening for decades and I have rarely considered this when I plant! It definitely explains my failures!
No, it doesn't. You probably have a lot to learn about basic soil building. Focus on the soil, build it slowly with mulch and photosynthesizing plants and it will grow healthy plants. Most of this video is simply not true, a bunch of myths that get spread around without people testing them out first. Elaine Ingram is a good place tonstart for learning about soil. One Yard Revolution made a bunch of excellent videos, including a series tesdting out gardening myths, most are false. Charles Dowding and Edible Acres channels are both great for expanding your understanding. The book Gaia's Garden by Toby Hemmenway is a good intro to permaculture at the home-scale. I've personally learned the most from years of watching Edible Acres and lots and lots of dirt time. Once you understand how to build soil, the rest is super easy.
My last garden was set on a concrete slab that used to have a shed on it. I used cinder blocks arranged 2, 3 , 4 and 5 layers from front to back arranged in four rows for access and filled the cavities of them with soil.(The last two rows had their bottom fourth brick turnred sideways making them only three deep). None were cemented only stacked in overlapping groups. all varieties grew well having their own "pot" to grow in. At harvest I merely unstack them and rearrange in new ways. Just not much room in the yard, and our soil in Tucson's foothills has too many minerals (and wild burrowing animals) to grow anything even with a raised bed over it. I did not know this trait about sunflowers...Thanks!
I love your idea about the concrete blocks😊 seems it would keep mice away too
Past owners planted a walnut tree in the vege garden. Every part of it contains juglone. We raise our vege beds to get round it, but sooner or later the juglone creeps in, and suddenly everything wilts.
Try using giant pots or stock watering tubs over a layer of bricks to prevent rooting into contaminated souls. I layer the bottom of my pots and tubs with a couple inches of volcanic pumice 1-2" gravel for a similar effect. The only tomatoes and peppers which have suffered were those that volunteered in the walnut zone.
Take heart; many NA native flowers di very, very well near walnuts, PROVIDED THEY GET ENOUGH WATER. If you want a reliable ground cover for dry, deep shade, lilies of the valley will serve.
You can look for lists of juglone tolerant plants. Most are natives of eastern North America (ie they have coevolved with Juglans nigra, which is probably the highest producer of juglone) and are not the typical/conventional garden vegetables called for in most recipes. However, some *are* edible, and thus you can create new recipes by experimentation. Maybe there are cookbooks developed by the Cherokee and other literate Natives?
Black walnut can cleanup all weeds around.
@@sepulkariy Not all. Many plants (some of which I personally consider to be weeds, like Kentucky bluegrass, Poa pratensis) are immune to juglone and thrive under walnut.
@@christal2641 I know it's just a typo, but reading about contaminated souls, nonetheless on halloween, has its own special value 😆
Under my walnut tree grows some grass and nettles. A very poor rhubarb (I knew of bad influence of juglon, should have replanted it) and long, long ago my mum tried growing asparagus between two walnut trees. It survived just fine for few years, but needed much care and when the attention was redirected elsewhere, it just vanished.
Here in the US, Black Walnut Trees are famous for suppression anywhere near their roots and even the fallen leaves. The suppression lasts even after removal in the soil for years.
Yup. Tomatoes are especially sensitive to black walnut toxins.
Yes, but some plants are fine with them/the jugalone. Just have to search for list of them.
Each state Extension You state Extension Dept. publishes lists of plants that thrive or suffer near walnut trees. Several factors should be considered. Most Juglone is generated by the roots, and decays over a 20 YEAR period.The most damaged areas will be under the dripline of the tree.
Over the century, our tree's canopy has been reduced by half due to construction next door, and a tornado, so I can only guess at the original dripline.
If you quickly rake up AND REMOVE all the FALLEN nuts, HULLS, leaves and buds from the tree, the accumulated effect of Juglone will be bydiminished.
Great video, thanks! Black walnuts, buckthorn, and creeping Charley will kill susceptible plants around them. On his list are fennel, sunflowers, decaying radishes greens, mint, garlic, onions, mint
I have a feeling you forgot to mention mint 😆
I don't think my mint kills a lot of stuff (I still need to deweed it!), but sure enough she's creeping like crazy, I knew that and should keep it in the pot, but I love mint and previous one was killed by weeds (spearmint), so when I got peppermint which I love the most, I didn't want risk it to be killed by weeds as well
I have creeping Charlie everywhere in my wildflower perennial native garden yard in the suburbs of Minnesota and it's beautiful, blooms and haven't seen any suppression of my unwatered wood chip mulch constantly blooming garden, can you point to a study that shows that creeping Charlie has allopathic tendencies? Thanks
I have noticed that about sunflowers. My veggies that are planted near them, try to grow in a direction that is furthest away from the sunflowers! I think if the veggies and other plants could dig themselves out and move...they would. 😂 Now I know.
I learned this the hard way about sunflowers. 🌻 I added them to my veggie garden this summer. They have been growing for years in the very corner of my property to the point that my house is known as the sunflower house in my neighborhood. People would pick them and it made me crazy. So I planted them near the tomatoes and peppers in a more protected spot. They looked great but, my vegetables suffered. Will try better next summer. 😬 Always learning, every summer!
I used to have a couple of grape vines. for the first few years any grapes we got from them were tiny and not worth harvesting. Finally on the fourth year we got a couple of nice bunches of grapes from each vine. Fifth year we had about half a dozen decent bunches from each vine. This was about the time we planted sunflowers alongside them to fill the space in that bed. This was also the last we saw of any decent bunches of grapes. The vines still got bigger over the years but they simply never produced much in the way of fruit. I wonder now if the sunflowers were to blame. By the time I moved out of that house those vines were pretty impressive but I simply abandoned them as they seemed like a lost cause. The sunflowers came back every year without fail.
Same
Sunflowers have invasive roots, and also suck up huge amounts of water.
Awesome video.
Yesterday I transplanted a bunch of silver beet around some baby sunflowers. Well now I know what my job is this afternoon.
move the sunflowers?
You are so right about the black walnut. My new neighbour two doors down from me has a very tall black walnut tree in her backyard. I gave her some hard neck garlic cloves to plant in her garden. The same garlic that grows very well in my garden. I even gave her some bone meal to mix into the planting holes. Not a single garlic grew in her garden. I wonder, is it the roots of the black walnut that poison the ground and therefore didn't give the garlic a chance to grow? Or is it the leaves that covered the ground in the Fall, right after the garlic was planted? The previous resident told me that she would love to grow veggies in the back of her garden but nothing ever grew there.
Walnut releases a toxin into the ground. It kilks apple trees and many other plants.
It's not so much "poison" as that the walnut is very good at suppressing competition.
@@victoriabaker4400 Its literally called Walnut toxicity, a toxin called Juglone.
Sounds like a good place for wicking beds with a sealant under them - concrete or plastic according to preference - the same as people who want to grow vegetables but find their soil is full of arsenic or other heavy metals. Soil full of walnut isn't poisonous to humans, but if it's killing their vegetables that's still something to seal out.
I'm not a gardener because everything I plant suffers and dies! I really try to be good to them, but ignorance is deadly. THANK YOU for such GOOD advice. I subscribed because such advice is GOLDEN if you want to grow things! Guess what! I planted a tomato plant twenty feet from a walnut tree and it had a nice tomato on it when a walnut (apparently) fell on it and knocked it off! That same tree actually hit me on the head with a walnut! I did you not!
That's quite amusing but it could have been more serious if it was a coconut tree.
Be aware that squirrels will throw/drop walnuts aimed at your head in order to chase you away from their food source
this explains why one of my Moringa trees didn't do well last year and looks amazing today. Fennel! i planted fennel with it! This video explains so much of my failures and issues. THANKS!
I was just about to plant sunflowers in a veggie patch - thank you for saving my future harvests!
Hoping my cucumbers and beans planted next to each other play nicely hehe
The cucumbers and beans should be fine. Ultimately planting stuff with risk is better than not planting at all. I do it all the time when space is an issue
But if you run into problems with those pests you know why 💁

@@joshmc5882 if that's all that's on your list you missed half the video 😵💫
So, could you plant the allelopathic plants in their own plot together or do they themselves need to be isolated from each other?

Here in the States, New Mexico, to be a bit more precise, we have mostly the same problems. My favorite plants to plant near each other are tomatoes, Basil, summer and zucchini squash and chili peppers. My friends used to call it my Italian sauce garden. 🍅🌶️🥒🍝
If it goes together, it grows together 😁
No one on the internet that I have watched has every mentioned this... bravo!
Although I haven't seen that many videos on gardening, I would agree with that statement!
I know about biodynamics that says which plants fight other plants (or each other), which are neutral and which help other plants / each other. My parents have a book on this, but I didn't read it, just the table with influences. It's not new concept, but I agree with you, this isn't talked about on gardening channels, I don't look for gardening channels, not subscribed to any of them, but sometimes they find me 😂 and if you tap one video, yt shows you more and they can have interesting titles, too, so somehow you end up watching them, even if you don't do gardening personally.
I'm mostly appreciating the fact that he's actually bothering to go into some of the nuances and is more accurate than most of the claims I've seen which honestly seem to be superstitious more than scientific. There's absolutely scientific understanding of this and that's what he's presenting here, but I have seen so much more of the BS on the internet that it's nice to see somebody grounded in reality😅
Something that might help…a garden map, illustrating what plants should go where, according to allopathic tendencies, and what plants favor their neighbors…just a thought…from an old vet, retired in the foothills of the Smokies.
Most of my favorite food plants are allelopathic. Fascinating!
We put peppermint plants in a bed some ten years ago. Everyone told us we’re crazy for the reasons you mentioned in the video. They were all dead within a year… the mint, I mean… other things grow perfectly fine in that bed…
Good warning about mints. Apple mint is a legit titan of the garden. Not allelopathic, plenty of plants mix with it, but the tall shoots block the light for other plants. That's the easiest way to prevent issues between plants, place them appropriately for getting the light they need during their entire growth cycle. Chop\drop to open some light will give the struggling plant a leg up. Only plant I have seen actual surpression from is black walnut trees, only some stuff will grow by them. Still a lot of good choices, some stuff isn't bothered by anything, like winter squash and indeterminate cherry tomatoes. Vines are strong in a general sense. Being able to root in as they crawl along is a huge advantage. My volunteer untrellised tomato vines always look stronger and healtier than the trellised and pruned ones. Makes sense, only one rooting area for the plant and it is being constantly wounded by the pruning, opening it up to infections.
This is really well presented: concise, useful, and really interesting. Many thanks for sharing!
I knew about most of them but not sunflowers! Makes perfect sense though, I think they were the downfall of my bed this year, I'd not grown them before. Great video, thanks!
In my area some farmers use daikon radishes as part of their cover crop seed mix.
Allelopathic, I think. Many moons ago, I was taught about how many eucalypts are allelopathic.
I had no idea about these veggies, though. I once read a companion planting book that encouraged planting garlic amongst your veggies. Thanks for this information. I'm in the process of planting some veggies, so this was a timely video.
Not surprising for eucalyptus to do that, they literally start forest fires to burn competition. Murderous trees. 😅

KOALAS are not so sweet as they look. Let's just say that every plant has its own constellation of talents/gifts to share and needs. There's a good role and good partner/s for everyone, but not every role or partner will be good for you.
@@christal2641 Yes, in a horticulture class, our teacher said that all trees have their pros and cons, so you just have to research and find ones that have traits you can live with when you're planning to add them to your yard or garden.
I have a Common Walnut which used to cover half of my garden (80’) ive pruned it back since moving in and chopped and dropped the prunings and composted them, the only reduction in growth was due to sunlight lost which is no longer a problem, I believe it is Black Walnut that produces Jugilone not so much with the common walnut.
Now I know why pole beans did so poorly two seasons in a row. I planted two sunflowers next to them🤯 I also had zinnias next to the sunflowers and they were just horrible. Thanks so much for such a good instructional video!
I love how I burried a bunch of "shitty looking" radish to release nutrients back into the soil a few months ago. Maybe ill go dig those up now 🤣
Me too, left extras in the ground to rot. Whoops
I dont like radishes anyway. Wont be planting those
@@vickigonya9432 they were honestly pretty yuck, but when we pickled them, much beter
Interesting about the mustard. I can't upload a picture but I have mustard in a bed with borage and a guava. All very happy in a raised bed.
I’m green with envy. You had a guava. I’m considering getting rid of mine. Healthy when I bought it three years ago, sick ever since! In the hope of perking it up I transplanted it into large pot. Still sick 🤮
@juneshannon8074 the biggest thing I've found with the guava is that whilst young they really don't handle aussie sun. I have mine up against a fence on the eastern side of property, lush soil mix of manures and potash, it permanently has a fruit fly net draped over it during summer and spring. It's only been there a year so not big enough to fruit yet
@@marciaferries1168 thank you Marcia. I doubt if I’ll have any luck with my guava. I have decided to give mine to the sheep, lol.
@@juneshannon8074if memory serves mustard primarily inhibits seeds not actual established plants but it's been a while.
I am curious, I have to grow hydroponically (have just started) and wonder how much of this applies to this method of growing. Is the surpression done by the root system (which would not effect me as each group of plants is in its own reservoir) or is there something in the air (as it were) that effects nearby plants?
Roots, but would be interesting to document your experiments
Yeah chemicals released through roots. Although moisture levels and soil composition are the two biggest factors on how strong the effect can be.
So I have no idea if growing in hydroponics would enhance or nullify the effect 🤷
This is jam packed with useful information 😊
@@CulinaryGarden1 I shall soon find out, I am guessing that the effect will not be as noticable as the only other plants that each root will be heir own kind. I am curious though if there is an opposite to this effect (in soil obviously) where have the root system of two different plants is actually beneficial, more than keeping pests or certain insect away from the plants that is?
I am a hydroponic and soil gardener too: the suppressive effect is reduced from the roots. If you have a separate reservoir for each crop as you describe, it will be fine. On the other hand, if you have a shared reservoir recirculating on many crops like me, it will go through the lot regardless of physical proximity ...
So, can I grow mustard spinach with other brassicas? We live in a very hot climate so now is the time to plant brassicas.
Also, I learned a bit about garlic last spring when I planted it with grapevine. The grape barely survived.
Awesome video, so much info. Many thanks.
I only plant store bought organic potatoes and they grow very successfully.
Just about to plant a whole load of sweetcorn and will put peanuts underneath those. Should be good up here in central Qld.

Sunflowers suppressed bean seeds and a few other plants in their proximity. What I found is that once a plant is established, like a biannual, it does ok the second year because it has a headstart on the sunflower seeds.
thank you, concise and informative, engaging - well done
Great video! Most informative gardening vid ive seen in awhile!
I have sunflowers throughout my garden beds and grow great tomato and onion and green beans all mixed through as well.
I grow lots of sunflowers every year in my flower and veggie beds and have noticed no issues
U.S. Virginia, Zone 7. I love peas, tomatoes, peppers, eggplants, basil and other herbs, beets, and many others. I once planted fennel and now HATE it. I'm constantly working to pull out the volunteers. NEVER, NEVER, NEVER plant Jerusalem artichoke (sun chokes). They are super aggressive and super persistent. I planted a small pot full and they quickly filled a 2x3 meter raised bed. They also sent runners under the bed borders, and I've dug the whole area out three years in a row. I'm crossing my fingers that I've gotten most of it out.
Love sunchokes. One of the best plants to grow.
Another reason why farmer plant sunflowers along the perimeters is because they tend to attract the kind of birds that eat insects, that eat the crops.
😮
Thanks for the warning. I like them, but I don't have space fir them to carry on like that!
Good video I didn't know about the sunflower thing but it makes sense because over the last couple years my flower garden has been overtaken by sunflowers and now that's all I have. Interesting thing to mention I live in a big potato production area and after we harvest the potatoes we plant these long white radishes they only grow for maybe a month and then it gets too cold and they die but it keeps out the weeds for next year and it's a good nematode suppressor we grow russets and nematodes can be a big problem good natural pest control
I let a volunteer sunflower grow in the center of a container with tomato plant this year. The tomato did terribly. Thanks for info.
I grow garlic, sunflowers, and fennel every year. Never had a problem!
Me too…it likely has to do with the quantity of each, how far they are from other plants, etc.
I do garden design, installation and maintenance, and I have often enough been asked by clients why some part of their garden is not looking happy. Many times it is a bird feeder - sometimes with just sunflower seeds or a bird-seed mix containing sunflower seeds - most bird-seed mixes in the U.S. have them. Black oil-seed sunflowers are the worst culprits. I am not always able to find a different location for the feeder that suits the client, nor to persuade them to use a mix without sunflower seeds or a mix with hulled sunflower seeds. (Those mixes are more expensive.) The issue seems to be the hulls, not the seeds themselves - the birds eat the seeds and drop the hulls. (The hulls can also be an irritating mess to clean up, depending on the location of the feeder.)
Brilliant videos been gardening for some years but learnt a lot from your thanks
about sunflowers. the seed shells falling onto soil 'poison' the soil and prevent any competition. i only use shelled seeds in my chickadee feeders.
Perhaps they are spraying the sunflower seeds like they spray grain, to desiccate them. Glyphosate residue can be composted out if given ideal conditions, or time.
@@Jbomb312 I think the seeds in question were falling from her own sunflower trees. I paid down a rubber ring under my bird feeder to reduce sprouting, but I am STILL killing dozens of morning glory seedlings there 5 years after I last stocked that feeder.
@@christal2641 I was replying on jhourlet's comment about the shells poisoning the soil, and yes sunflowers can be allelopathic but the real poison is glyphosate which is used in commercial grain production. It's much more damaging than the shells themselves.
I hadn't known that about radishes. Good to know! I also have peppermint in my lettuce & kale bed, but so far they all seem to get along. I don't mind if the mint takes over and wins out -- it's my favourite thing in the garden.
Great video, just discovered your channel thanks.
After watching this, i have a something to pique your interest on a video topic, on the common thought about 'nitrogen fixers', in the way that you mentioned their benefits.
I was down a youtube rabbit hole on legumes and it was suggested that if you let the legume go to bean, they use up that nitrogen, therefore they only add to soil as a cover crop.
Brilliant video - answers so many puzzles and anomalies I've had on my allotment. Thankyou!
Thank you for the education about these plants and how to be successful at growing a vegetable garden.
Im a novice, and this information is so helpful!
Just found your channel - your tomato pruning tutorial is the best!
I love informative videos like this and this is one that I have never heard before which is great. Many of the garden channels, which I love, do a lot of the same content. Refreshing and informative
Great video, I'd love to see one on companion planting too! 🙂
Same here, I'm not sure if my info is right but heard garlic next to roses keeps pests away and that basil is good to grow next to tomatoes.
This one of those “I better write this down” kind of videos! Thanks!!
I have been making this mistake (planting sunflowers, garlic, mustard greens and mint) every year and yes I have beautiful sunflowers but terrible harvests on everything else nearby. Thanks for helping me identify the problem.
Oh my gosh, there is SO MUCH I didn't know!!! The only thing I knew in your video was walnut trees. I wonder if mint is why my blackberries died there but did so well elsewhere. I'll need to watch this again with a pad and pen. Thank you.
Can you make a video of what we should plant next to each other? and if we are doing rows with 30 inch rows and 15-18 inch walk ways how will this work?
Look up companion planting. 👽✌️
Can vouch for gum trees being allelopathic. We have huge gums on a reserve just the other side of our back fence and their roots invade everything even flower pots. I'm sure their roots and dropped leaves exude growth supressing compounds into the soil. Then there's the physical damage from a constant barrage of twigs and gum nuts which perforate leafy vegetable plants.
Having said all that I am currently growing quite successfully directly under their canopy in wicking beds. My growing soil is completely serparated from the earth soil, it's the only way.
I love the starter friendly presentation of this information. Plus with the titles for future investigations for me too. You grow a lot more then I do but still great information to help me getting started
I love your videos & I really appreciate content from an Australian gardener as a fellow Aussie!
I paused the video and ran outside as soon as you said sunflowers because I have a little bed with cucamelons, tomatoes and sunflower and strangely noticed not long after planting the sunflower in there the cucamelon vine slowed down and before that it was growing rapidly. Would you move the tomato plant if it’s only young and not have it next to the cucamelon?
If it's already there & established, i personally would just roll the dice for this season. But i also grow lots of stuff so if i have a handful of failures i don't care to much
Do leaves from these plants cause problems with compost, especially radish leaves. I put some into my compost heap yesterday. Great video, so much to think about and take on board, I am hoping to grow fennel in my back garden next year, so now I know I will have to do it somewhere else. Are large planters any good for that, I have limited space, so use a lot of large containers. Many thanks again. Jane
I posted this a few days ago and it has ended up near the bottom of the list, so I have re posted it. I hope that you dont mind.
Why can’t plants learn to live together in peace?!
Hahaha! Love it!
Who? Plant politics can run rampant!
gotta plant companions and avoid planing natural enemies too close together
😂😂😂😂
Because each type of plant wants to survive. There are plants that will grow terrifically well together. The Navajo have grown beans corn and squash together - they call it the three sisters.
The juglone exuded by black walnut trees does not affect corn. I grew a block of corn directly next to a black walnut and it did just fine.
Paw Paws are also juglone resistant, as well as a number of other plants. Including some vegetables.
It's not like nothing *ever* grows near walnut trees... look at a forest some time. ;)
Yeah but you can say that about all the plants on this list. It's never a plant suppresses the growth of all other plants, it's more this plant impacts these other plants in this way under these circumstances. Black walnut however is definitely one of the most aggressive plants in nature that people regularly encounter however nothing can hold a candle to conifers. Those things know how to monopolize realestate😂. I'm kind of surprised he left them out well including Black Walnut because usually they're part of the same conversation along with a few other trees kind of going through the gradient of how much do they have with the plants around them😅. It's kind of cool because in natural forests those iconic trees change everything about the ecology in their war on other plants.
I learned pretty quick that some plants just do not like sunflowers. pmuch any cucurbit crawls away from them and others sort of grow very weak. Might be my last year of growing sunflowers as they suppress other plants and I don't even get to use the seeds because birds get to 'em
Also I saved the link so I can watch this again. Good to see an Aussie take on this, because most content about companion planting is US or UK based and not entirely relevant here.
Nasturtium can be very aggressive. I had it next to a young Kiwi plant, and the Kiwi was growing really poorly. Now I have some other flowers there, and the Kiwi is doing much better. I love Nasturtium in the garden because if flowers all year and you can use all parts of it as spice or food decoration.
I planted nasturtiums at the ends of my 12ft long raised strawberry bed for the first, and last time, this year. The plant turned into a flowering thug! Smothered a 3 x 4 patch of strawberry plants and deposited a few million seed pods which I have been hand picking out of the bed for the past 2 days. I threw the seeds into the abandoned field behind our home.
Here in Minnesota, I use Moonflowers and nasturtiums because their seeds are not hardy over our winters, so no jungle of strays. I do save there seeds -- indoors. Our native morning glories try to pull down my dwarf fruit trees.
@@wrongwayconwaythey're basically a weed in my community garden and every time somebody shows me one I'm like oh that's weird I'm not sure wait no I think I know what that is it's another color of it. Yeah it's going to kill everything else in the bed, I don't know why but it does not play nice. 😅 I have still yet to figure out what you can actually grow with the thing, so you know I always recommend people move them into the corner or something if they want to keep it.
Do leaves from these plants cause problems with compost, especially radish leaves. I put some into my compost heap yesterday. Great video, so much to think about and take on board, I am hoping to grow fennel in my back garden next year, so now I know I will have to do it somewhere else. Are large planters any good for that, I have limited space, so use a lot of large containers. Many thanks again. Jane
Yep. I learned sunflowers when I grew them in a tub with tomatoes
Excellant video. Thank you for moving around your garden while you recorded. I love seeing new layouts and how to add more garden space. Question: are your raised beds filled with dirt/compost?
Raspberries are my favorite.
Wow I am surprised at how badly my garden has been arranged because of other people planting things where they shouldn't be. My sister put Tomatoes next to my Glass Corn, Acorn squash, Grapes, Raspberries and Butternut squash.
I planted Apple mint along the edge of my long garden bed with a 30cm gap between them and everything else in hopes of creating a defensive barrier to pests. I don't know if it was helpful.
My sister also planted Jerusalem Sun chokes with Russet potatoes and the Sun chokes seem to have killed the potatoes.
Sunchokes are sunflowers so yeah, maybe it killed the potatoes
raspberries weren't even mentioned in the video, were they?
@@gg-gn3re what's your point? Why are you trying to agitate me? This is a friendly channel with no reason for a comment like this. Plus I was sharing a personal preference that has literally nothing to do with you.
@@MikkellTheImmortal Are you going to answer me? I asked a question... what do you mean "what's my point"
@@gg-gn3re no you did not ask a question. You insulted me and insist that I answer you.
It doesn't matter if raspberries were or were not mentioned in the video. I was telling him about my garden, not his, you petulant little worm.
How about you answer me a question. Do you know what manners are?
I have some fennel growing right next to a wattle, the wattle is booming. Will fennel get rid of couch grass. Maybe sunflower would get rid of couch. Maybe I can throw raddishs on the couch. Going to have to grow some wormwood I think
Lavender (not a vegetable) in my experience is extremely allelopathic (I just learnt this word thanks to this clip).
But yes I have planted lavender to bring in the pollinators only to realise over time that they should have their own allocated bed 🙂.
Guh… I intentionally planted garlic and onions in the same bed as my brassica seeds thinking they would keep pests away. Everything is growing so slowly - lesson learned!

It's that Simpsons meme of all of Mr Burns' diseases trying to fit through the same door and getting stuck.
😂
They probably get on together well enough because they can't steal the other plants' nutrients.
So fascinating! Thank you!
Interesting about dill and carrot, because dill and wild carrot (queen anne's lace) self seed and grow wild next to each other in my backyard.
Does the carrot form good root stock? Because that's usually the main issue
@@veronicabrown2328 Ah! I have no idea, as Queen Anne's lace (wild carrot) is grown for its flower! They both attract lacewings to my garden, which take care of aphids for me.
U can eat queen anne lace like carrots & eat the greens of queen anne lace cooked with seasonings u like. Very yummy here in NE Texas in the spring.
@@Kat-Knows Oh, that's so cool! I'm questioning whether it's real QAL though (with the black centre dot). I think mine is called dill ammi (false QAL). It's super tall. I'll have to get some real QAL and sow it away from the dill and try eating it, like you!
@@LilacDaisy2 Poison hemlock looks similar to QAL, but is much taller. Be careful. Read up on it.
Im In dongara. Im having trouble growing anything in this limestone bedrock stuff. We have to dig out so much of it to get anywhere and then there's the wind and mega bugs. Im new to this so I have a long way to go. thank you for you tutorial
Love the knowledge. Excited for spring to put into practice. Thank you 🥦🥬🧅🧄🫛🫑🍆🥔🥒🥕🌽🌶️🍅
Who knew! Thanks for the information..you have just saved me from a lot of grief and failure.
Great information. I grew potatoes and garlic together, and they were very happy.. I got a really good crop out to both of them. I learned something from your. Thank you. New subscriber.
I just eat the wild strawberries in my yard instead of growing them. I actually do but in all seriousness, I use grow bags in my garden. It tends to isolate any soil fungus and I’ve had success using them. I’ve also grown heirloom tomatoes and heirloom cucumbers close to each other with no ill effects.
I grow manalucie tomatoes and white wonder cucumbers. They are heirlooms today but they are what my grandmother grew. The tomatoes love 90F days so they grow well here in the American South. The white wonder cucumbers are a little milder than the store bought here and are good in salads.
I’ve never had that issue with sunflowers, I grow them every year in my cut flower patch in my garden along with plenty of other flowers - cosmos, dahlias, zinnias etc
Maybe it don't work on aster family plants?
I think it's mostly because they suck up so much nutrients. If your soil is really good it might not matter at all.
I grow my tomatoes and sunflowers together, never had an issue. But I also have rich compost that I put down every single year.
I use sunflower to wipe out weed patches. Grow a dense grove of sunflowers, clear it out, it's as if nothing was ever there. Never thought about it being a problem in isolated cases. Maybe I should.
Lots of good info in video and comments!
Great video. Any suggestions of how to get rid of the mint taking over my garden? 😕
Excellent information as I didn't know this. Being new to gardening, can you grow the plants that kill others together in the same raised bed. Like cabbage, broccoli, cauliflower & cucumbers?
❤ your channel & garden. Hope mine will look like that next year.
My fennel is right long side my snow peas . Both doing great.
Excellent video mate the best i have seen on the subject thank you .
Grew massive amounts of fennel, on the sides of my cabbage, wombok, and cauliflower beds, also grew heaps of beetroot with daikon radishes grown in the same beds.....
Good information. Thank you!
This is amazing information, thank you for this video! Would it be good to use allelopathic plants to suppress the growth of weeds around the garden? I have certain areas of my garden that I'm still planning what to do with, yet they are constantly a nuisance with the amount of weeds that pop up there.
I've done corn next to sunflowers and they do well, but I did have runner beans get slowed down by them
I never knew this! So i assume that we shd keep aliopathetic scraps out of the composting bin?
This was super helpful, thank you! I’m in Sydney and have been enjoying your seasonally-appropriate content :) I have some cabbage in the same bed as a couple of strawberry plants, although not immediately adjacent… the cabbage are just seedlings still, maybe I should relocate them 🤔
😊 thanks for the gardening advice.
