A Good Start for Roses: Nitrogen Supplementation
Вставка
- Опубліковано 27 чер 2024
- Yes, I'm singling out a single nutrient for special attention: Nitrogen. As mentioned in my previous videos on fertilizer for roses, nitrogen is only one of several nutrients required by roses in relatively high quantities, so why single it out? Because it's commonly deficient and doesn't stick around for long in the soil: regular supplementation (within reason) is likely to improve growth and flowering without much risk of accumulating to unhelpful levels.
Now my preference has been to supplement the nitrogen levels using a green amendment, like alfalfa, which also adds a wide range of other nutrients (at much lower levels) and organic matter. That said, the plants don't know from where the nitrogen comes, so do what works for you!
Here's the cut flower nutrient guide I referenced in the video:

Thanks! You are my personal garden reminder, complete with instructions! I don't need to journal or set reminders. I prune when you prune, I fertilize when you do! And since realistically, I'm not doing a soil test, I'll choose an organic fertilizer source so I don't overload my soil. 😊
Good call with the organics. I figure you can't go too far wrong with something (like alfalfa or manure) that ultimately came from plants, and so replaces what was taken from the soil
Thank you
I also use alfalfa pellets. They are so easy to apply and you get a big bang for your money
Hello Jason, here in Florida is Kind of difficult growing roses, but with your help I'm doing pretty well, thank you for the advice. God bless you always.
Always great to watch and learn from your videos. Alfalfa meal is good natural option for N source and it has hidden most potent natural plant growth promoter(Triacontanol) although less talked about. I think it is good idea to add nitrate N source with alfalfa to sustain and promote growth vigorously.
Thank you Jason! I am a beginner just 3 months ago! Purchased 30 roses 🌹 comprises of hunting tea, grandiflora, Florinda and climbers! I learned a lot from your channel! Keep it up! I watch you 6-10 times a day! lol! Thank you ! I am ha I f issies with leaves getting pale! Southern Cali here!
So glad you mentioned that you have a UA-cam channel, have just watched the first two, on pruning and on Nitrogen etc. I so enjoyed your talk at the club on Wednesday, and delighted to learn so much wisdom and common sense from you. You're my GURU for roses now !!!!!!!!
Thanks Sheila!
Alfalfa pellets are the best for my roses and the rest of my garden. Thanks for the tips!
how can you know?
@@FireflyOnTheMoon I have been applying alfalfa pellets for years. Good strong growth!

Hi there! Wondering if you wouldn’t mind to share some of your knowledge. I’ve never used it for anything but animals. I have hundreds of plants in my yard like Japanese maples, conifers, natives, etc…Could I just broadcast the pellets across the whole growing areas? Or do I have to address each individual plant? Thank you!
@@cindyl3916 I broad cast the pellets all over my garden. For roses at the base, I put a 2 handfuls of pellets now then another in mid June.
@@scallywags12
You’re so awesome! Thank you a ton for answering 💚I’ll definitely do that!
Thank you Jason, another great video! Blessings 💞🙏🏻
Once again, thank you for sharing! I really like this style of communication - conclusion first, reasoning later. People's attention span is just too short nowadays
love your content, from australia :)
Thanks - and even though I get the seasons backwards!
Thank you so much for this info!
My pleasure.
Good to see you again! Nevada USA
thank you Jason, happy spring!! dandilions and ants waking up on the island, the organic gears are about to really kick in!
What you just said is quite the same as what we do for ourselves.. “ before you take anything it’s essential to know what you’re lacking.. “..i think address you as Dr. Jason from now on
Wow, half a t-spoon of 20 percent nitrogen added 4 times in spring! I have long suspected the manufactures of rose feed have been encouraging us to be more generous with feed than need be, in a similar way to the toothpaste adverts on tv. You always see that huge line go on the toothbrush when all you need is that pea size.
Jason your thoughts on the rose feed introduced more recently you may have heard of, it’s just one feed per year. Have you any thoughts on this please?
Some ferts are treated to be controlled-release over a long period, and that's a fine option - although they tend to be a little pricier than other options.
Very valuable advice there. Your grey and wet climate looks so similar to ours in the West of Ireland!
Pretty drab this time of year!
Fertilizer is such a rabbit hole. I doubt you can ever know enough to get it perfect. On a monocrop you may get close sometimes, but temperature and weather conditions generally can change nutrient uptake so much. When it comes to gardens with many crops with different requirements, we've got no hope. Best to take Jason's advice and focus on the important ones. Then add a wee bit of iron and some seaweed extract because that never fails to help.
I use arborist woodchips around my roses and also chop and drop around them and my roses (and other plants) are lush and green, grow quickly and bloom profusely without any additional fertilzer. The worms traveling around my bushes in all of that organic matter fertilize them beautifully. I also do not spray anything on them. My garden is pesticide and herbicide free. I do live in a good climate for rose growing (CA).
Deep in the snow still here in Calgary but thanks for the reminder; I'm going to pick up my Act-Sol chicken fertilizer tomorrow as it worked really well last year (30+ years of rose growing, and most visible positive difference so far).
Good to hear. Thanks Dianne!
I myself help manage a small backyard Nursery. Quite literally yesterday it occurred to me like a light bulb going off. 60% of our inventory has stalled. No test is even necessary. Complete lack of growth. So all this week we're having to repot with nitrogen additive.
Thanks watching for entertainment and knowledge to use on my vegetables in Austin. No roses here...
Lol. Well at least the concepts apply across a wide range of plants!
Thank you for all the information. I am from Trinidad.
Thank you.
Thank you for debunking the urban legend I so often hear (even from my own Rosarian Society) of giving all roses Epsom Salts regularly. This would have been such a poor practice for me, as my soil test showed very high magnesium and very low calcium. Since Cal and Mg influence the levels of each other, if I had added Epsom, not only would my magnesium have gone even higher, my calcium could have gone lower. The agriculture experts' advice, based on my soil test results, was to never use epsom, but to add gypsum (to increase calcium) and retest in a year.
Thanks for demonstrating the point perfectly! Some clay soils are dominated by magnesium or sodium, making gypsum a good remedy, but even that needs to be taken on from a position of knowledge instead of guessing. I'm glad you got a test and some good advice.
Hello Jason, could you make a video of the rugosa roses an how to take care of them? thank you in advance
Much love, from New Mexico ❤😊
I just fertilized my roses with alfalfa pellets in April. Maybe I misunderstood, because I did 2 cups of the alfalfa pellets per rose bush. Was that too much? Would 1/2 cup be better? I've been really enjoying your videos. I've been watching a bunch of them as I only just discovered you a week ago. I've learned a lot and appreciate the time you take to make them. Thank you!
It's a bit more than the recommendation, but on the other hand, it's pretty difficult to overapply in any significant way because it requires biological activity to release the nutrients over time. I did another video on alfalfa recently, and the recommendation by the supplier was similar to the 1/2 to 1 cup range, but she also mentioned that applying again in 6 weeks would be fine, so I bet your soil (and roses) will handle it just fine.
Thank you again Jason for the content. Roses are a curse to me but I've recently began grafting and results are looking very promising. Cuttings just never make it down here 😂.
Nicely done - I've tried grafting a couple of times, but it's not something I've ever become proficient at.
Good for you.👌
Take your time grafting. The key is to carefully line up and match the edge of the stems in a veneer graft and one side of a top graft.
Many people over emphasize the need to match stalk sizes, but in all honesty, typically only one side lines up anyway.
Simply make a nice clean cut, match one edge, bond and seal together with wax tape, and wrap with a flat rubber band for added strength.
Most grafting brings an average 60-80% success ratio depending on the species of plant and of course the quality of scions and health of the plant.
Roses can certainly be particularly sometimes because some species struggle to bond well.
Glad you are having success.🤙
Hi Jason do you have any advice on crown gall ? I've seen a lot of people in rose groups complain about it
Most important note of the day, know your soil. 💯%
Now that my roses have actually been in the ground, at least as much as I currently have, I will be adding a mixture of, one bag of inexpensive potting soil (3/4 cubic ft) and 1/3 bag of all purpose sand, spread evenly around each of my roses.
Some might ask, Why not fertilize? The answer is, not enough soil to absorb that fertilizer.
Back to that key note, know your soil.
My situation is unique, but many people might be growing in pots, sandy soil, or like me, a limited amount of naturally available soil.
In these conditions it is important to take extra care in understanding your particular conditions in order to properly fortify your soil.
The reason I use pre-made potting soil is because I know that the amount of fertilizer is fairly weak and pretty well mixed throughout the bag of ingredients. The other, more important reason is, I am adding valuable precious soil to each plant that is lacking, in an affordable convenient way.
Is this method realistically practicle? Not really, but in the short term it certainly provides the necessary nutrients and soil needed.
Eventually I will be hauling and stockpiling mulch and landscape green waste to build soil resources.
For anyone struggling to figure out the whole fertilizer process, this just might help you keep your precious plants alive while you learn what your plants need.
The first step is knowing when and what to do.
The new growing season is upon us, for some it might be a bit early, others already going strong, either way, here's to great success!🤙
Question regarding when to apply to the potted roses. The roses have started to leaf out but the weather has remained cold. Highs in the 40s, lows in the 30. Does it matter at this point or wait another 2 weeks. NYC zone 7.
If you're going with the alfalfa I'd say go now. For conventional fertilizer I might wait.
Great info Jason! I'm considering trying the alfalfa, but I've read it attracts mice, voles etc. Have you found this to be a problem?
I haven't but it's also pretty moist here at the time I apply, so the pellets turn to mush pretty quickly. If it's a concern, you could give them a quick soak ahead of application and work them into the top layer of soil. The faster they begin to break down, the less an issue with rodents I would think.
@@FraserValleyRoseFarm Great idea - thanks for all the info you provide!
I put down a cup of alfalfa on each of my roses, and was going to add a slow release fertilizer. I bought a bag of Mills Magic as I saw it was formulated for roses by a rosarian, but the NPK is 6-5-1 which seems unusually high in phosphorus for roses. What would you suggest? Should I use the Mills Magic or is there a different fertilizer you recommend for the roses? I can always use this fertilizer on other plants like my flowering annuals so it certainly wouldn't go to waste
It's definitely more P than they really need in general (unless the soil is lacking and it needs correction) but then most plants also have pretty modest phosphorus needs, so I'd spread it around so as to not overapply on anything.
@@FraserValleyRoseFarm thanks! Is there anything you suggest to apply for the K?
Sulphate of potash (SOP) if you're not committed to organic sources. Wood ash or greensand for organic sources. Most manures are also decent sources.
Thanks!@@FraserValleyRoseFarm
Been using organic fertilizers for four seasons, and I can't imagine going back to synthetics. From what I have observed in the past, synthetics tended to push new growth on roses far too fast, making the shrubs more susceptible to insect damage and leaf diseases. With synthetics, I was always fighting off massive aphid infestations. Now, about the time the aphids show up, so do the beneficials.
Great insight - I do prefer the slower (and lean) organic approach myself. Despite the clear growth benefits of sufficient N, it can tip over into "too lush" and spike pest populations if you're too generous.
@@FraserValleyRoseFarm A bit off-topic: Walking around our Drift roses this morning, I saw a beetle-like bug I had never seen before. I took a photo and did an Internet reverse image lookup. Imagine my surprise when I found out I stumbled upon a ladybug larva! Never saw one before.
I need advice on a really messed up rose. Shrub i think. Its full of really thick branches. Should i cut the whole thing all tge way back? Its a mess
Hard to make a call from afar, but yes, if it's pretty tangled and quite vigorous, you can give yourself a bit of a blank slate by pruning way back.
Can you please discuss about once blooming roses in climates with no winter or dormancy period. I wanna see if I can grow those beautiful once blooming roses like constance spry and some damasks.
That would have to come down to experience in your climate - but if there's no dormancy period at all, I think you could expect those roses to have difficulty timing their growth an blooming.
@@FraserValleyRoseFarm Can you recommend some damask looking repeat bloomers? I wanna at least have one that looks like a damask wih the delicate look and the prominent button eye. I'm thinking sydonie. are there any more that look like those?
ua-cam.com/video/WzHjF28g3mU/v-deo.htmlsi=h1JJ2MD0vY18vOcN
so.. in terms of application do you suggest to split the 3cups per year in sort of 1/2 cup per month from March to July?
You bet
@@FraserValleyRoseFarm Thanks!!! If my ask... It would be a great gift a video on how to manage planting densely to avoid bare soil around roses. I found hard to manage keeping tidy form weeds the roses bed... Thanks!!
The goal is roses (and consequent 'hips') for COLOR interest on a property. You know, Nice... Pretty, I promote that... I can dump my old worm castings at the base. The Go to is Miracle Grow rose food in water solution. Sorry for being a half assed rose farmer....
I sure don't judge. Worm castings are great - and miracle grow isn't too bad, if a little high in phosphorus for continuous use in a garden soil.
My roses are in 15 gallon pots. Do I need to remove the rose from the soil refresh the soil and replant? Also what about just adding manure?
I definitely watch for signs to see if my container roses need a refresh - but so long as they're thriving, a topdress of manure could do the trick.
@@FraserValleyRoseFarm what signs would let you know that a complete repot is needed?
When they've rooted/filled the entire pot, sometimes that'll show as the plant drying out quickly in warmer weather. Other signs may be nutrient deficiency.
How would I apply this advice for a potted rose in a 24” pot? I assume potting soil also loses its nutrients over the season.
Yes, but I generally go for a more complete fertilizer solution for those in containers / potting soil. Here's my video on rose fertilizer overall: ua-cam.com/video/865vhlajZp8/v-deo.htmlsi=Sok-MLsEah9PjGxR
@@FraserValleyRoseFarm Thanks, Jason…
what do you think about using blood meal?
Good source of N. Probably around 1/4lb per plant or 2lb per 100 sq. ft
0:32what are the little green grass like plants near ur rose?
Allium bulbs emerging if I'm not mistaken.
So I have some 20-0-0 fertilizer can I put that in the hole where I put the roses. Its granular....I wouldn't want to burn them or anything!!! How come your roses behind you are in tires?
It's pretty concentrated, so I'd sprinkle around on the soil surface and then just work it in a little, but not right in the planting hole. Here's why we use tires: ua-cam.com/video/u0-cnrOZvRo/v-deo.htmlsi=8IGO7x8Ex5cgaYZB
I used a fish fertilizer that is 2-4-1 on my roses and I now notice that the leaves look like a stippling effect on them...is that from too much fertilizer or the wrong ratio of N-P-K?
I usually associate stippling with pests - like spider mites or leafhopper (although that's not necessarily the cause). Sometimes there can be temperature-related lockout of iron early on as well. But 2-4-1 isn't so far off the mark that I'd expect any acute problems.
@@FraserValleyRoseFarm ok thanks Jason...I will take a look to see if there are any pests
Is there any job available at fraser valley rose farm?
No, we're not hiring
@@FraserValleyRoseFarm i got mail from your side for job
No you didn't. Not anything we sent. It could be a scam attempt
@@FraserValleyRoseFarm it was scam
Have you ever used Calium Nitrate as your N?
Yes - particularly useful when doing a liquid feed because of its easy solubility.
Where is everyone getting their soil testing done these days?
Varies a lot by region - locally it's someplace like Terralink.
Seaweed doesn't contain any nitrogen, btw
Thanks!
For the rest of the world: 10 grams of N per square meter per year.
Thanks
Thank you Jason very helpful information. 🪻💚🙃
