The weed growers have been using 4 parts water to 1 part lemon juice ("Real Lemon Juice" in the green bottle at the store) for decades with great success on mildew. The acidic lemon juice kills the mildew immediately.
I have heard that dilute apple cider vinegar also works in spray form. That's what I tried today, before stumbling upon *this* video! Best wishes!

You also need to remove any low lying leaves, any leaves that cross over to another plant, and any leaves that overlap each other. You basically just want a canopy above the ground that has the leaves well spaced. Another good way to do this is to drive a very long stake into the ground and train the vines up the stake to get the leaves as far away from the ground as possible. This allows air to flow around your plants, which prevents the fungus from growing by allowing the moisture to dry out and allowing the vine to get sunlight. Air flow is about the best way to prevent and/or stop powdery mildew.
Thanks
I was thinking the same thing, since I live in the Mid- Atlantic and battle All Kinds of Mildew/Fungus due to the Heat, but more so the Humidity that is a staple in East Coast summertimes. The only way to succeed here as a Gardener of Anything, is proper pruning for Airflow. I am a Professional Garden Designer. My specialties are Native, Cottage and Herb, but I have Designed many Modern, Traditional, Woodland and even a couple with Aquatic Features. The Humidity here is such an issue for any garden, any Gardener and so many plants! Not to mention, it's exhausting to Work in!! Lol
Countess 71 uff the East Coast humidityyyyyy!
I'm sitting here reading YT comments and sweating my buns off on Long Island.
I just bought a over wintered cucumber plant a couple of days ago, made sure to pick one that had no spots on my leaves. Today I removed (out of caution) a ton of leaves that had what looked like white shiny spots on them, almost like how after it rains you get dusty spots on your car. Although, they're not dusty? Or white.. they don't look fuzzy at all! But they're extreemly brittle where the spots are and crumble when you pinch them. I have no idea if that's mildew or not. I'm so bummed, was looking forward to finally having cucumbers this summer, as last summer when I started from seeds the mildew ruined them before they really grew.
So should I be removing all leaves that are low on the plant? It's a patio snacker plant, not sure if the same rules apply to them as the big guys. I'm also new to anything garden wise, this is only my 2nd year having flowers/veg/fruit!
Thank you for sharing your hints on powdery mildew!
I have hard time trying to grow zucchini here in Malaysia. A year of trying seeds refused to germinate. Until one day I decided to soak the seeds overnight in plant growth hormone solution (my instinct told me to do this! Haha!), and it worked, the seeds germinated 100%, my zucchini plants grew well to flowering stage.
But just as I started rejoicing for successfully growing zucchini to flowering stage, disaster struck, all plants and all leaves were attacked by powdery mildew, the plants stopped growing and flowering, now look like they are about to die.
"...like somebody dumped baby milk powder on your plant..". Exactly what my zucchini plants look like! You put it like it is!
Thanks for the tips, I am sowing anew zucchini seeds, will use milk to take care of the problem. From Kuala Lumpur, Malaysia
Wow! That zucchini is awesome!! I love how much produce you grow! We've been struggling with so much rain, humidity and excessive heat lately that I haven't been able to grow much these past few months. Luckily the heat should be slowing down soon, but we will still have rain, pretty much everyday until October sometime. Thank you for everything you do! I love stopping by to see what your growing next. There is so much beauty nature has to offer us, right at the tips of our fingers! Have an amazing weekend!
That's crazy, Stacey - rain til October? Hope you get a little dry spell so you can get some harvests! Nature is amazing, it keeps me in awe. Have a great weekend yourself!
Thanks for such a simple solution! Loved it :D
I am having powdery mildew problems now and this is my first time trying to grow food and I am using a raised flower bed. I am going to try this,..thank you
Thanks, I caught the mildew just in time. It was weird because I look at my vegetable garden and flowers every morning to see if they need to be watered, make sure I didn’t get any unwanted visitors like deer, rabbits, and chipmunks etc., before watering the garden. This is only my second year with a garden, and I only grew a variety of sweet and hot peppers, tomatoes, and green bell peppers. So I expanded to cabbage, kale greens, squash, zucchini, and strawberry ( my granddaughter wanted me to grow them, strawberries are my mom and her favorite fruit)
Yesterday there was absolutely nothing on my zucchini and squash leaves. They were was just beautiful greens healthy looking leaves. I don’t even have any yellowing leaves. I then watered them watered them as usual. ( it was unusually humid, early it was and the day before was cool outside)😋
That evening, I was showing my brother who came to visit the garden. I notice white powdery spots on 1/3 of my squash and zucchini leaves. I don’t see any signs of mole in the soil. I didn’t know what it was, but I know it wasn’t suppose to be there. I immediately went to CZcams.
I finally came across your video. I’m getting ready to prune the leaves of the ones with the mole, and later on today I’m going to buy some milk to make your concoction. I don’t keep it on hand because I’m lactose intolerant. Thanks very well explained☺️ Have a blessed day.🥰💜 You have a new subscriber here!
I gave this powdery mildew this year ! I didn’t know what the heck it was !! Thank you SO MUCH for this info 👍cucumbers and squash are hit hard 😒, going to try it !!!
Thank you for addressing this horrible nuisance in the garden!
I think I found some PM on my pea plants today. They were getting old and dried up anyway so I decided to rip them up. I'm going to resow directly.
Those large zucchini are perfect for stuffed zucchini on the bbq. Tomatoes, red onions, bacon (pre cooked) feta, all chopped, balsamic vinegar, s & p. Cut zucchini lengthwise and remove seeds. Slice a bit off the bottom so it sits flat and chop and add to your filling. Fill your zucchini and put on the bbq or even in the oven for 30-45 minutes, depending on the size of the zucchini. Can drizzle with more balsamic or even olive oil, if you like. It's what my family requests every time they see the large zucchini in the garden, lol. Yummmmmy!! Can also stuff with a rice, ground beef mixture.....whatever you like! Soon, you'll want your zucchini growing as large as possible!
I wanted to add.....I was taught to cut the zucchini leaves off where the stem meets the leaf. It isn't hollow, there, so there's less chance of insects getting into your plant. I
Thank you so much for your recipe 👍
Thank you for the useful advice 💚
Thank you so much for nice informative video from🇬🇧❤️
Good video. I would suggest keeping a plastic pail handy, and putting the contaminated material directly into.
Thanks, great tip. I have this powdery mildew for the first time ever! 😞💚
Thank you for posting this video Kim, will definitely give this a go on my spaghetti and butternut squash trellis.
I've always use buttermilk and spray the plants before they flower were the tips I
got many years ago from somewhere i no longer remember. Happy gardening.
Great tip! I will try that next year. (Do you use it 'straight' or make a solution, like she does?)
Thank you for an easy solution ❤️
I was doing this earlier today! One of my favorite treatments, the plants really respond to it.
Hello Cliff, it really does the trick - you should know with the amazing giant pumpkins you grow! Have a great weekend!
Great info. Thank you. Pulled my cucs last year, realize the mildew can be controlled now, so will have cucs next year. Will change my watering habits as well.😁
Your garden is gorgeous!
Awesome thanks. Did not know that milk would work.
Beautiful Garden
We've had so much rain in here in Maine, This is the first we've had this mold. I'll try the milk potion! tyvm CaliK
Very good. Thank you for sharing my friend. Have a good day
Such a lovely garden!
Thanks for posting! I will be using this on our pumpkin plant. The white mildew had spread, after trying a spray with vinegar. Fortunately the pumpkin is doing very well and is starting to turn orange. Have pruned the lower leaves and infected ones, good reminder on cleaning cutting tools after 👍
I grate my zucchini and freeze it to use through the winter for zucchini bread. Everyone loves it.
me too.
Just had to do surgery on my beautifully trellised cantaloupe plant that seemed to get powdery mildew overnight!!!! Praying that all the cantaloupes currently growing will not suffer.
I will be trying this method. Thank you
I was just dealing with powdery mildew on my cucumber plants last night, had to look for your old video on the subject! Nice to review great tips, thank you!
Hello Meiko, perfect timing! And good luck getting that PM under control. Thx for watching!
Thank you! It’s wet and humid this summer in Georgia way too early!
This is so helpful! Thanks!
Thank you for this video😊have followed your advice game changer for me.
G'ay CaliKim n Jerry. Awesome tips. Thanks so much for sharing. I'll keep it in mind [I hope], lol, for if I get it in my garden at my time of the year. I'm still continuing with my comedy of errors. I need to put my mini green house beside the shed instead of beside the door at the front of the shed so the southerly winds, which we refer to as our August winds, doesn't blow it around the yard again. Once I've situated it I'll need to sift more potting mix to obtain seedling mix and start planting seeds again Hey,I almost forgot to tell you, I ordered your book from Barnes n Noble. Can't wait to see it. Nice visiting with you. See you next time. Blessings.
Always love hearing your garden adventures, Helen! Thanks so much for pre-ordering my new book - can't wait for you to read it! Have a great weekend!
Thumbs up...you always do a great job with your channel. I meant to use the milk on my cucumbers this year but I didn't get around to it so I am replanting now for some late summer harvest.
I'm here in Calif also and yes my squash has powdery mildew. I'm going outside now and hopefully can save my squash!! Thank you caliKim29 for your awesome videos 🙏
It does not cure it. It is better as a prevention. Before you see it. But, can't hurt.
Thnx for the info...I'm a first time gardener n while I knew my zucchini plants had powdery mildew I wasn't sure what to do about it! Now...I am! 😊
Calikim great episode on powdery mildew. I've never tried the milk /water spray. One tip I give customers for cucumbers is to do succession planting so if you have a plant die you have another one on the way.
We had sago palms that had this. Wish I had known about this before we finally pulled them out! Good video!
Glad you enjoyed the video, Bonnie. There's always next time! Thx for watching!
Thank you for sharing this method
Thank you very much for for your gardening tips
Middle of June 2023 here in the La Tuna Canyon neighborhood of Los Angeles… unprecedented winter rains and both May Gray and June Gloom have resulted in powdery mildew on my more susceptible rose leaves.
I like your milk solution. I’ve tried both a vinegar and a baking soda wash - spray bottles, and finally hand washing with a dishwashing soap and water regimen. The sodium bicarbonate didn’t really help, and the vinegar was a little hard on the leaves, causing them a chemical burn. So I’ll be glad to try this milk product. Thanks for sharing. Daniel
Going to try it!
Thank you my roses deserve the love
Just found your videos. Love them!
enjoyed your video Kim
I wish I had known this sooner.
Cant wait to have beautiful zucchini plants like yours! Do you have a video showing all your fall pollinator flowers? I have the seeds now and was wanting to see what the flowers look like. :)
Thank you for sharing this remedy. I'm an amateur grower and even that word doesn't do me justice. I grow in containers on my deck and for the past two years I get flowers, but no fruit and yes, I do add nutrients and water carefully. But, I do not give up hope. I've started microgreens indoors and that is 100% growth every time.🥰
You could knock one out of the park with that one lol. Seriously I enjoy you're videos the info helps a lot and You I have a beautiful garden thanks for sharing😎
Wow that is very beautiful 😍 thank u for ur time n tips
My hedges look like a snow man every year love your vids thank you
So thats where it's all coming from.
I did try the milk & water, sprayed on my cucumber leaves, am very please. Thank You very much for the idea.
Thanks for explaining thoughly.
Thank you for the tips... you are awesome 😎
we will try this on our cucumbers
Wow Kim those zucchini are huge!
Perfect exactly what I need to do first thing today for my squash leaves are yellowish and mildew looking 🤣 looks like all my squash leaves in the container are mildew 😌first time gardener here and I planted three plants 🌱 in the container . They have flowers now good they will bear some squash ❤️🙏
Nice video. I didn't know aboat the milk/water blend. Thanks. Steen, DK.
Thanks for the information
Nice video. Thanks for the tips. Around 5:10 you said "anti-bacterial effect on the powdery mildew" but you should have said "anti-fungal effect on the powdery mildew."
My rosemary plant has PM and I will try your tip…thank you!
Great video. I am going to try on my fig tree... Thank you
Great tips.
Excellent information
Great! Thank you!
Great video!
Thanks a lot I'm going to spray my garden got mildew on my planting garden too
I saved and planted some seeds from a pumpkin given to me by a friend but have ended up with zucchini plants and also have got powdery mildew. These are great tips.
Pumpkins and cucumbers can be treated the same way too. Both the pruning and spray.

Are you dealing with powdery mildew in your garden? Thanks for watching!
I've read that you can just use whey, instead of the whole milk. Have you tried that?
I've never tried that, Rose, give it a go, and let me know! Thanks for watching!
thank you kim you have always helped me in my garden...i have a queston....my mint plant got these stupid green worms and they ate every leaves on it how do i get rid of them ....? thank you so much
Thanks I'm going to give this a try. It's been raining everyday here and I prune weekly it's helping but I want to be safe.
Give it a go, SoulGardener, you might have to apply more often if it's raining every day. Good job keeping up with the pruning!
Thank you , i will try it out on my tomatoes.
I use this spray on my lime trees works great
Thank you for the spray advice.
You should place the formula in your description comments for easy reference.
I always grow cucumbers and squash with built in powdery mildew resistance, it makes all the difference!
Klaus
@TL C Probably genetically modified, but better to steer away from them, as they are not healthy to consume in the long run
Thanks for sharing 👍
I have the mildew problem on my container squash and I cut them off late and I will try your method. Thanks. 👍🇨🇦
Thanks.... I have this problem right now
Most farmers/growers do not cut off the infected leaves, since doing this makes the wpm become air-born. A much better approach is hydrogen peroxide mixed with water, used as a foliar spray. It'll kill and prevent the spread of mildew. Another great solution is Trifecta Crop Control, which is organic and can be used right up until harvest. Cutting off the mildew covered leaves should only be a last resort. And each leaf should be bagged up(while still on the plant, then cut off, to prevent it from spreading as much as possible.
Cool. I regularly prune my squash. I've also noticed squashbug eggs, so I'm removing those as well. I have a lot of yellow leaves lately, but also a lot of new green growth. I have been using a hydrogen peroxide and H2O solution to clean the leaves of fungus.
Just regular hydrogen peroxide and spray?
😫😫😫 I wish I knew what it was when I seen it a few days ago. I just took out a whole gray s squash and pruned my other squash plants. I also sprayed with neem oil. I should’ve watched this video first. Super bummed, but was comforted by you stating it happens to everyone’s garden at some point. Thank you.
Hi!!! Thank you!!! My neighbor and I live in San Diego, and we both have had, and are having PM on our cucumbers and squash. I tried very mild soap on my cucumbers and it didn't work. I'll be switching to another veggie. My neighbor's squash are just starting to get the PM, so I'll pass this info to her.
I'm going to try this on a lilac that I worked into Bonsai.
Great video! I am always having issues with powdery mildew and squash vine borers in mid to late August. Milk with water works, but I get better and quicker results from either a tablespoon of baking soda and dish soap mixed with water or spraying a neem oil mixture on squash and cucumber plants. I live on the border of zones 6b and 7a and won't have time to regrow summer season plants. Therefore, I will be starting my fall garden (carrots, radishes, turnips, peas, and lettuce) once my squash have run its course in a couple of weeks.
Neem kills bees, if plant is flowering,. So use preflowering. Milk and baking soda ok
I could watch this lady ALL DAY...
I’m having a huge problem with powdery mildew on my pumpkins! Thank you for this video! Now I don’t have to go out and buy something expensive!
Get that stuff on mine every year smh luckily its usually not until later in the season so doesn't usually effect my pumpkins
Thanks, thought I was doing something wrong. This is my first year trying to grow squash.
Glad to hear it, Eva. Don't you just love when this happens and you are really doing it right? What else are you growing and where are you roughly? so GREAT to have you following along! CaliKim
Useful info...
Yes!!!!!! It got out of hand from high humidity. Took my whole garden
First it was powdery mildew then low and behold cucumber beetles. I saw them and had no clue what they were or how bad they could damage. I haven't watched her video yet,but I can say that peroxide slightly diluted but still bubbles worked wonders for me on the mildew. The beetles however idk they are viscous.
Neem oil as a beetle egg preventive
Awesome!...hopefully I never get it, Mahalo for the tip ms. Calikim
Hello Hawaiian Buds - I hope you never do too! I would think it might be a possibility in Hawaii where it rains often tho. You might want to do it as a preventative measure. Thx for watching!
I just spray water. It works. My first garden, I've learned that PM loves dry conditions rather than humid.
Thanks. I have one plant that is completely covered. I'm going to pull that plant and spray the rest as a preventative measure.
Thank you for simple solution.I have bottle gourd plant.Hopefully this will eliminate white powderly bacteria.
Of course I had power moldy problems but lost the plants for knowing no fix.
Thanks and I will try.
Just pruned off a sad amount of PM off my pumpkin plant. The plant is large so I am hoping it recovers with fresh leaves before I have to trim anything else off, I have some nice pumpkins on the plan I don't want to lose.
Very helpful 😊I have this problem with my plant 😩
Nice video, last year I had all that mildew on both my squash n cucumbers. This year no squash. Next yr. I’ll try that milk and water.
Thanks for your video. Another technique that should work is using a field horsetail brew, since it has antifungal properties.
Good to know
