Wow, it’s good to know there’s so many options to get rid of powdery mildew! Congratulations on reaching 300k subs!!!
Greetings from Serbia. Thank you for great gardening tips!!
As a new viewer, thanks for the great tips. I'm right there with my garden. Looking forward to more summer growing tips from your videos. Thanks
Thanks Al!
Water and whole milk 1:1 worked very very well
I've gotten it every year. Wish I'd seen this video years ago. Next year is the start of my fight back. Thanks
Great information! Thanks so much. I always look forward to getting a notification that you've posted another video.
Brian, I have powdery mildew on peas this year. Thanks for this video. In the past I've trimmed and that's it. Went out and got some neem oil today. Look forward to seeing some changes!
On another topic, I've had some mushrooms come up in my raised bed. Should I pick those out? They are dying in the heat of the day
Hello, I am a beginner gardener with my very first garden. I lover your channel and all of your detailed information. I love how you describe things in detail. I am a cancer survivor and trying my hardest to be organic, but I am really having a hard time with whiteflies in my pumpkins. They are everywhere, the leaves, the stalks/stems, and on the ground. I had given up and bought Sevin dust, but after reading more about it, I am really not wanting to use it. I enjoy the bees, and not to mention being cancer free!!!! Can you give some advise, please????
Congrats on being cancer free! Name oil works really well and is totally safe and organic.
@@NextLevelGardening Thanks, I will try the Neem Oil. I am in zone 7b, North Carolina. Do I hear a slight southern drawl once in a while from you...? Not my neck of the woods, maybe Texas area?
Anyway, I have learned much from your channel and enjoy watching. Thank you for helping us beginners!! I am still trying to catch up on all of your videos.
Funny you should say that. Maybe? Born and raised and lived my whole life here in S. Cal. But 3 out of 4 of my grandparents are from the south and even though my dad lived in S cal all his life people used to detect a bit of an accent. When my sister was little she had a heavy drawl..it was funny. Your the first person to say that about me but I guess to the trained ear I might have a bit of one. 😃
300,000!! Oh my!
Congratulations 👏👏
Thank you! I can't believe it!
111skirby For sure, I’m constantly recommending his channel. I’m a novice gardener, but quickly gaining experience thanks to Brian’s videos!
What about treating the soil as prevention for the next season?
I am growing beef steak tomatoes this season and I know you don't have to trim them back the same but I have been trimming anything thats touching the ground and also I have been thinning a lot of the branches.. I have a lot of fruit on the plant its white and turning green at this point .. hopefully they get ripe soon. but I have been thinning them back a lot to provide airflow. lost a few zucchini this week .. they were small but not maturing or getting large so i think the flower stayed on the end too long .. only lost about 3.. I am letting one of them grow as big as I can get it so I can harvest seed they are regular black beauty... I haven't watered all summer except when I transplanted for a few days... we have been getting rain 1-2 days a week.. I am trying to cut back on watering because it can get expensive.. but I am still getting a really decent harvest so far... anyway hope you are doing well.
Hi Brian.
Thank you for posting so many educational gardening videos.
Love your garden.
I tried diluting 2tsp of Neem oil to a gallon of water.
They didn't mix and patches of oil floats on top.
How do I get to spray my plants with powdery mildew ?
Need your help n suggestions.
All my plants are in ICU now.
Please help, anyone. Thank you.
Yep. For insects I put 2 tbsp neem oil and 2 tbsp dr bronners sal suds in 1 gal of water and put in a deck sprayer. Last year had some bad powdery mildew on my cucumbers, hit the mildew with the spray and next day looked good.
Sal Suds is a WONDERFUL product for CLEANING, but NOT to put on your PLANTS!! it contains: Water, sodium lauryl sulfate, coco-betaine, lauryl glucoside, fir needle oil, spruce oil.
Dr. Bronners CASTILE SOAP is SAFE for PLANTS!!
Hi Brian, I'm startung to see PM in my tomatoes but also black spots and blythe. What method should I use to get rid of all. I have been very diligent to cut the leaves but I'm afraid I will cut more than I should. Thank you!
I was just out of town for day and come back and visiting my garden and see all my squash plant got it and just like you said all the old leaves. Guess what all the leaves are packed in shipped in to dust bin.
I use 1 tablespoon potassium bicarbonate and 1/2 teaspoon liquid soap in one gallon of water. Works better than baking soda.
i needed this
Hi Brian, Thank you for your videos I am learning so much! I went to buy Neem oil but they were out of stock, I was advised to purchase the All Seasons Horticultural and Dormant Spray Oil. Is this as safe to use as Neem Oil, your opinion would be appreciated.
See if it is OMRI certified. That will tell you it is safe.
Lmao thank you for teaching me i dont even have powdery mildew, just a cool looking squash i failed to label!
As Arnold S. said in 1990, “danks fo de tip!!!” 😉👍🏻
Thank you!!
You're welcome!
Neem oil question- I followed the link you provided on the brand you use off amazon. I can’t seem to find a shelf life on the photos in the link. Do you know how long a bottle lasts? I’m not sure if I get this larger bottle... will I be able to use it next year? I’m in Illinois. Help 🙂
Mine seems to get the cucumber
Is there anyway of reducing the amount of powdery mildew in the soil?
Anything I can do to the soil before planting to help prevent powder mildew?
I have neem powder. Can I dissolve in water and spray?
I have Black Knot on my plum tree, are any of these remedies good for curing this?
What zone are you, our gardening Guru? I'm in zone 10a. Near the coast we have a milder climate.
I have it on my cucumbers. When I replant, it attacks the new cucumber plants. How do I get rid of it so I can replant cucumbers?
This got the only pumpkin I ever tried to grow. I tried a bunch of things, none seem to work.
From these tips on powdery mildew if seems like urban gardens are doomed.
HELP.....Hi, I'm from Puerto Rico and I think I made a huge mistake with my tomatoes. I got distracted while mixing the baking soda and aspirin solution and forgot to add the rest of the water so the solution was too concentrated. Today they appear burnt and I'm very scare to loose them. Some idea of how to fix this?
If it isn't too bad, it may come out of it.
Be careful with the baking soda. I used that one and it burned my plants.
Same here! I won't use that again!
baking soda never works when there is already a heavy outbreak with powdery mildew
Remedies @9:00
Yeah get tough 💪 use a spray bottle 😆
How do I send pictures....
Instagram?
@@NextLevelGardening yep.... instagram.com/foodstuffstoronto
Sent some pictures... Bottle gourd plant.. potted on a high-rise balcony...
It's the first time I'm planting veggies and saw this white stuff, thought it the water lol. Destroyed my plants uh
I used baking soda and all my babies are dead
Don't spray it when the temperature is hot or in the afternoon. Evening and early morning are better and concentration matters too.
As a beekeeper, I have to disagree that Neem oil is pollinator friendly. Neem oil, in addition to being a fungicide, is an insecticide. Honey bees are insects. Now, it's true that Neem oil is not a contact killer of honey bees but anyone who can adequately spray a squash plant without getting the spray in a blossom is a genius. Forager honey bees love to collect pollen from squash blossoms. They get covered with pollen, fly back to the hive where other bees will clean the pollen from the bodies of the foragers. The pollen is used to make bee bread as food for the developing bee larvae. It is packed into the cell for the developing bee to eat. If the pollen they collect is wet with Neem oil it will kill any deveoping bees that ingest it. An entire colony can be killed in this way if enough Neem oil makes its way into the hive.
Every bottle of Neem oil I have ever bought has this written on it: " WARNING - This product is toxic to honey bees. " Look for it and you will find it. Spray Neem oil very late in the day at dusk and most bees will be back in the hive for the night. In the morning the spray will be dry and the risk greatly minimized.
I've never used neem oil & now I won't. I just discovered powdery mildew on my zucchini and cucumbers and sprayed with baking soda/water. Will that harm the bees?
I read that it can be toxic to birds which is why i decided not to use it. Have decided to go with Hydrogen peroxide and i spray very late at night when all the bees and birds have gone to bed. Thank you for the info.
@@sherimetschan961 I use neem every week as a preventative measure, but I do wait until dusk or see don't see any pollinator movement to do my spraying. It hasn't stopped my pollinators from visiting at all but has helped keep other bad bugs away. I've had very few pests visit my garden, but I will have to disagree with the video that neem kills powdery mildew on contact as that has been my biggest garden issue this season. I have turned to the Sulphur to try to stop the powdery mildew, at present it is still my battle.
I haven't had any problems this year at least not yet. Thanks for sharing. I'll keep that in mind.
Pruning sounds good 👍 Wish I could prune a few pounds off myself.LOL.Thanks for the video.
Lol. If only it were that easy.
Lol me too! ❤
Ooh, Brian - you reached 300k! Congrats.
Thank you! Can't believe it!
497k now!!👍👏
631 & counting...
709k!!!!!!
Brian, I love you and you great videos even if you are "corny"! 😁 I am 64 years old & have gardener my whole life, but I learn something with every video. THANK YOU!!!
Drip irrigation on an automatic timer is probably the single best thing I’ve done for my garden. I have far fewer pest and disease issues and I don’t have to worry about cracking tomatoes or blossom end rot from inconsistent watering. I have a soaker hose under the mulch in the bed with my zucchini this year and so far I’ve had very little powdery mildew issues. It doesn’t hurt that that bed gets ~10 hours of sun every day as well.
Congrats on 300K subs! You definitely deserve it dude!
I agree. How long do you set your timer ?
Jig89 I live in especially hot and dry area. 100°+ for almost 3 months with no rain all summer. Right now I run it every 12 hours for 45 minutes. At the beginning of the season when it’s not as hot and the plants are still small I just run it once per day (at 4:30am) and that’s just right. I turn it off for the winter and manually turn it on as needed.
@@garden_geek I live in a similar environment, Sacramento county. I asked because i am trying to narrow the causes for having no fruits to bear on my 3 plants despite planting them in April. insufficient watering (2-3 days of 15-20 mins via soaker) or the intense heat.
I live in the driest state of the driest continent on earth and still get powdery mildew. South Australia.
Agree, we have had a dry summer in Tassie, and my worst hit dahlia was rarely watered and the least crowded of all!
Congrats on your 300k Brian! You deserve it!
I have something funny to tell you... I planted some new radishes a few weeks ago and they were coming up just fine... I got up one morning and they were chewed up... I sprayed them with a mixture of peppermint oil, tea tree oil and soap (that is all I had on hand) and I got up this morning and no leaves were there ...chewed to the ground! I thought, wow! What kind of bugs eat that much in one sitting? That was a lot of chewing in one night! Well, it is not a bug, I found the culprit! A ground hog is living under our shed... I just kind of put salad dressing for him/her on my radish leaves and he/she like it ...A LOT, lol. So tonight I made a concoction of a Tyland extra hot peppers slurry in water and I sprayed it all over my garden... 🙄😞... I hope that it will deter it from munching on my veggies... I don’t mind sharing but He/She is eating a bigger part of the pie. What would you do to deter the new comer?
Thank you again for your videos. May the Lord keep blessing you and yours. Have a good weekend.
Nicole Hervieux I got some bugs too. Chewing everything. You go at night using a beam light and just catch them. If you have sluts put them in your compost pile or bin. They should be happy there eating kitchen scraps. I catched about 20 to 30 every night. Now my garden is almost bug free. Ja ja ja.
I (very) liberally sprinkle cayenne pepper and half the time mix in an equal amount of cheap ground black pepper. This gets spread all around the outer edge of my beds and on the ground around them. It usually does a fair job but if it rains all bets are off immediately. You know how squirrels, chipmunks and assorted other critters like groundhogs lead with their noses and they're always sniffing everything? Well, when they get a noseful of ground pepper it can be really entertaining as they jump up and down squealing and sneezing but it does, for a short time anyway, keep them away. Unfortunately when you get into a rainy period, and it gets washed away or diluted, like I just went through it's like they get their revenge and go after the garden that much more aggressively because I pissed them off. Anyway, that's my solution for the munchers.
@@sandramatos6409 Um.... I'd like to see her catching sluts to put in the compost bin, let alone the groundhog! ;'D
You can try moth balls around your garden to keep squirrels and other critters outside they hate the smell….for bugs I use wood ash mixed in the soil
I had golfers last year wiped out whole cucumber garden twice. Built a bigger stronger fence around my raised beds
Masks & socially distancing on plants ... hilarious.. had me rolling 🤣🤣🤣🤣🤣
I read on the label that you should NOT use Neem Oil on plants that produce food for consumption.
Hey I've been using a spray of worm tea on the leaves with neem oil and peppermint every week. The worm tea stains the leaves a little but other wise all my squash plants have been mildew free. I'm growing up a trellis and keeping the lower area bare too. So far so good🙏🏽
That's great! Thanks for sharing.
how much neem do you use , I tried spraying my plants with a neem oil mix in the evening and i think it may be too strong beacuse it makes my leaves turn yellow and die
@@wmh9783 I use the neem oil with the worm tea so that may be the difference since the tea protects the leaves . I honestly don't measure things much. Make sure to do it after the sun starts to fade in the evenings only. I wet the fronts and back of leaves with the solution it keeps the mosquitoes away too.
@@Samantha-jc5mu i'll try it , thank you !
You suggested Neem Oil some time ago and I’ve been spraying every two weeks on melons, squash and roses. Staying ahead of PM is the way to go. A method to tell if it’s PM is to 1) see if it rubs off and 2) see if it smells like mushrooms.
How do you always know what I am facing? 😂
Lol.
I was thinking the same
Sigh. I didn’t get my squash vertical
Me too. Gonna try to gently guide them up.
You might not be able to get them verticle from the roots but you can start where the growing tips are now and go vertical for the rest of their growth.
I successfully staked my yellow squash and zucchini plants based on a prior video you did. I also chopped the old, diseased leaves off along the bottom. 🙂
Does the neem spray need to be done early in the morning? The bees are out here around 6:30 AM and I worry about the plants being wet and hurting the bees. Is applying at night frowned-upon?
Spray very late in the day. Bees are back in the hive ususally. I am a beekeeper.
Uuuuh.... well, I’ve never had powdery mildew till now... as for what I’ve done? Nothing? I guess the mini-ecosystem in my garden isn’t really suited to it or something? But at least now I’m armed and ready for it for when it ‘WILL’ arrive. (Now I’ve acknowledged it’s existence it’s sure to come at me in force... -_-’) THANK YOU ONCE AGAIN FOR THIS VIDEO! (And Neem oil is on my shopping list since forever but I can’t seem to find any! Even on amazon France they only sell the one for hair and body that costs an arm and a leg... which is kinda ironic now I think of it... :P)
My dingy of a roommate said I should use 409 to remove the mildew. Guess she forgets it's poisonous and we eat the squash.
I only had powdery mildew in my garden once. It was about 20 years ago and it got my lima beans. The only things I do for fungus control are adequete spacing between plants and staking/trellising to keep plants off the ground. I also mulch heavily with grass clippings to prevent soil splashing in heavy rains.
I am LOVING your videos. Each one is so timely for me as a novice gardener. I was particularly interested that you could combine the neem oil and the Neptune's fertilizer. I have one good sprayer and feel like I'm always wasting these high quality products because I have to clean one out before putting in another. I have extra fish fertilizer in the sprayer and didn't want to waste it.
I'm not sure if it's powdery mildew but its white & fuzzy on my rosemary plants. I don't want to lose them! What is this white fuzz & how do I get rid of it & still be able to eat my rosemary? It happens inside the house & outside. The plants are quite large now but WV winters are not conducive to leaving them outside plus they're in 2 gal containers. I couldnt find decent plants this year when we were shopping.
Thank you for sharing! Very useful information!! I have some hydrogen peroxide I’ll try that!
Love your channel, you are one of the best on YT! I really appreciate your straight to the point approach. I am also in So Cal, and growing my first raised beds this year. So far tomatoes are doing fantastic, but the powdery mildew on the squash, melons, and cukes has been horrific! Too late to stake, I am pruning. I have used all the sprays you mentioned, and I'm keeping them alive, but I keep getting new outbreaks. Tell me, is it ok to combine sprays? Like hydrogen peroxide and baking soda? Or hy. per and mouthwash? Just wondering if a double whammy would be more effective. Also, is it good to add in the liquid fertilizer to the same mixture?
One more thing - any advice for leaf miners?? Thanks so much!
Doing my squash vertical, and I’ve been pruning but nearly as much as you 😅 thanks for the great info as usual!
Thank you!
Just spotted the first white mildew on my zucchini. I cut the leaves off and the party continues!!
I’m in to deep I went on a trip and was gone for 5 days and my family was taking care of my garden! Mildew over load and leaf over crowding a lot of work to do! Man 5:01
First comment haha
Yup!
mohammad moasher that is a nothing statement, not an interesting, or informative comment.
I want to thank you for recommending Neem oil. I immediately got some and it works very well against creepy crawlies that nibble young seedlings. I have not tried it against powdery mildew as yet which I tend to have on roses, not so much on vegetables. I sprayed the tomatoes in the hope of keeping tomatoe fungus deseases at bay for a while. So, again, thanks for the tip! I enjoy your videos very much although the weather here in the high North of Germany cannot compare with your California weather.
This is so timely - I just noticed some powdery spots on my pea leaves, argh. Thanks for this info!
It hit my cucumbers.
Neem oil solution has destroyed my plants in the past.😐
Well, this is scary. It's my first year so I have yet to see it, but now at least I know what to look for and what to do to rid the garden of it once I do see it. Thanks as always for the information!
Youre ready!
Hi! Love your channel and am subscribed!!! Your tips and suggestions are well presented and very useful!! Sadly I am not able to get neem oil here in British Columbia, Canada 😱😳 I have tried the baking soda method and it does work in addition to constant vigilance!! Thanks for sharing your wisdom!! 🤠🇨🇦
Got my cold pressed neem oil( important) off amazon,no issues.
How often should I spray it from milk and water Spray
Subscribed man thank you god bless 1:04
This has been my first year gardening & I have used many of your tips. Thank you! Can you do a video on when to start your fall garden based on zones? I’m in Connecticut.
So glad... and yes its in the books!
Why don’t you talk about cucumbers?
I just cut off leaves.. they product fine..
I use neem oil for this problem.. sometimes I spray milk 1:8 ratio 👍
I'm so glad I found your video! Although it may he too late for my plants. Thanks for the advice!!
Yes! Thanks for suggesting spraying a few leaves first. I live in Texas and it’s very hot and humid and my zinnias has PM so bad. A few weeks ago I found the baking soda, dish soap and oil remedy in a completely different person’s video. Well, I sprayed all of my zinnias because the mildew was so bad! I don’t know if it’s too hot here for the oil or if the mixture was too strong but I fried them all. It’s probably the 100 degree heat here mixed with the oil. Do be careful and test a spot first. Great advice!!
Thanks. Yes probably the heat.
California Garden TV, thanks. I should have known better! I’ll use neem oil from now on.
It is more reliable. Test it too though
California Garden TV, okay, thanks!
@@carolhutchison222 I fried my peppers last season, i didn't shake the mixture in between spraying plants and some got too much oil. I really like using the neem oil mix and alternating with the peroxide when it gets bad. If you use any oil based sprays make sure to shake it well , and then see if the oil is truely mixed in, sometimes different dish soaps are stronger, like dawn versus an natural soap, you would need more soap if using natural.
what kind of sprayer are you using in this video?
Milk did nothing for me. I had it bad and was treating every other day with something different just to alternate. I found trimming the worst leaves a few a day - never too many - helped a ton. Regardless of the massive PM problem it still produced the best Butternut squash I've ever seen.
I had it last year in my first garden on the zuchinni plants. It was in late Aug or Sept, toward the end of the season. I cut the leaves off, but some lay on the adjacent empty bed though most were thrown out. 😉 Yikes, didn't know they needed to be trashed... hope that doesn't bring it back. Well, I am armed with knowledge and supplies this year and ready if it does! Thanks.
Perfect!
Found this so interesting but I would really love to learn more about how you trellis your yellow squash and zukes. This makes sense for the viny-er plants, but the method for yellow squash baffles me
Just did a video a week or 2 ago about that😀
California Garden TV gaack! How did I miss that? I watch them all
California Garden TV actually I did watch that. I’m new at this, so I crave more detail than that video provided. That one was pretty high level. Looking for more of the actual steps for growing yellow squash up (using small words and short sentences 🤪), rather than an overview of methods available
Lol. Trust me its easier than you think!
I like your hat. Good video 👍🏼TY
Does powdery mildew get on mush melon plants too
I lost all my zucchini plants today. 😓 Had mildew, didn't treat it fast enough. I've grown zucchini for 4 years. This is the first time I've had this problem. I didn't do anything special the last 3 years. This was a learning experience will grow them up a pole next time. That way they can get air and it will be easier to do preventative treatments. Oh well there's next year.
I've never had powdery mildew (yet) because it's my first year gardening! hahaha :) BUT leaf miner is driving me crazy!
Lol. Neem for leafminer!
Hello Bryant. Very good as always.
I have a diferent issue with my Squash plants, I do get flowers but no the one than produce the fruit.
Any idea what is the issue.
Thank you
He has a video about squash. He tells you why that happens. I don’t remember which one, but I think it was fairly recent.
I used neim oil but lost the battle not sure what i did wrong
MI Gardener says not to use it in the hottest part of the season.
This is such great information, THANK YOU! Also, based on your recommendation my husband and I just watched The Biggest Little Farm movie. It was incredibly inspiring and moving. Big thanks for that!!
Congratulations on 300K!!!!!!!!
Thank you! This is so helpful for a novice gardener!!
will Neem oil hurt lady bugs?
Good scientific evidence for whey
Great tips Brian!!! Awaiting the powdery mildew usually around October for me.
Lol. I just noticed powdery mildew on my cantaloupe. Good timing
My neem oil says its ready to use on the bottle
by squash you mean zuchinni?
Too bad we don't have neem oil in Canada
Omg i got to ask for help
Baking soda does NOT work
