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.

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.

Hey the milk works! I have had the mildew problem for years. I stopped growing the susceptible plants because of it. But now I am bringing them back. Hard to believe but it does a nice job. Thank you.

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 grate my zucchini and freeze it to use through the winter for zucchini bread. Everyone loves it.

Good video. I would suggest keeping a plastic pail handy, and putting the contaminated material directly into.

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

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

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.

Thank you for addressing this horrible nuisance in the garden!

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 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 KZfaq. 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!

Thank you for the spray advice. You should place the formula in your description comments for easy reference.

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.

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.

Yes!!!!!! It got out of hand from high humidity. Took my whole garden

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 !!!

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 was doing this earlier today! One of my favorite treatments, the plants really respond to it.

Awesome thanks. Did not know that milk would work. Beautiful Garden

Great video. I would also spay the ground under all the trimmed leaves after they go in the trash. Do not forget to put all the infected leaves into the garbage bin not compost. Cider vinegar, Hydrogen peroxide, baking soda all change the pH on the leaves and can kill the powdery mildew in 24 hours.

Thanks, thought I was doing something wrong. This is my first year trying to grow squash.

Garlic pepper tea is also fantastic for mildew as well as being a form of organic pest control

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.🥰

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.

I did try the milk & water, sprayed on my cucumber leaves, am very please. Thank You very much for the idea.

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."

In Eastern North Carolina, our humidity laughs at milk spray and diluted hydrogen peroxide spray. I have bought mildew resistent squash and pumpkin seeds from Hoss Tools and am seeing better results. Additionally, I have used copper spray and it will stop active powdery mildew in its tracks. Milk spray just won't cut it in super humid areas.

A few years ago I tried using milk in my garden to cure powdery mildew and it did nothing. I even got some raw unpasteurized milk and it still did not work . This year I have using 1 oz of 70% neem oil and 1 tablespoon of baking soda per gallon and it's working great. I did spray my tomato plants earlier in the season with copper neem oil and baking soda and no fungus issues. Been doing applications in the evening

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!

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

I've been gardening for 5 years and this is the first time to hear about using milk to treat powdery mild. I won't have to buy anything special, I always have milk on hand in the fridge. I'm going to start spraying my squash, melons and cucumber every 7-10 days in hopes that it will prevent powdery mildew from even happening.

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.

Thanks. I have one plant that is completely covered. I'm going to pull that plant and spray the rest as a preventative measure.

😫😫😫 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.

try making zucchini-brownies! they are so tasty and you cannot even taste the veggies, so kids love them :-)

There is a much more potent version of this. Try adding 1 oz of crumbled chocolate chip cookies to the milk mixture. Or maybe some Hershey's syrup. I tried this, but but my powdery mildew kept getting worse because i kept sucking all of the spray out of the nozzle. It tasted better than the squash would have anyway.

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.

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!

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.

I don't seem to have a problem with powdery mildew here in central Washington. It may be to hot and dry. The biggest problem seems to be earwigs. I use diatomaceous earth and it seems to help deter the insects. At first glance, a person might think it is powdery mildew the way the powder sits on the leaves. I harvested three cucumbers and some of the bunching onions today. I can't wait to eat them.

I love your videos give me lots of iformation ,i do have a problem with my zocciney plants and i am going to try this mathod, by the way thank you so much, also i am gonna say that i like when talk ,your voice is very nice and the way you talk .🥰🇨🇦

I have pottery mildew on my squash my cantaloupes my watermelon leaves I'm going to try what you just stated with the milk and the water wish me luck and I hope that everything goes well thank you for the advice

I always grow cucumbers and squash with built in powdery mildew resistance, it makes all the difference! Klaus

I grow my own weed in Colorado . PM Is a major problem, don't want to smoke that 😂 MILK. I use low fat or 2% and mix 1:1 with water. Spray all leaves. Works better than anything else I've tried while in flower. In veg there are way more options. Real pain in flower though. Edit:oh good she goes over milk! It really does work. You can use any milk, but low fat or 2% works better because the sprayer won't plug as easily, that's the only reason. Also I've heard the 1 part milk to 9 parts water, but I like the 1 to 1. Never smelled sour milk either. I was really worried about that first time I tried it.

Thank you for sharing your hints on powdery mildew!

Thank you! It’s wet and humid this summer in Georgia way too early!

I just spray water. It works. My first garden, I've learned that PM loves dry conditions rather than humid.

Helpful hint: Don't compost any plants/leaves that have powdery mildew or any other condition.

Thank you for simple solution.I have bottle gourd plant.Hopefully this will eliminate white powderly bacteria.

Thank you my roses deserve the love

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! 😊

I'm using milk spray and pruning, but a few zucchini plants have still been overtaken 😢. First time gardener here, I thought of pulling them out, thanks for giving me the confidence to do just that and protect the rest.

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.

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 ❤️🙏

We got powdery mildew on our squash plants that spread to our zucchini and pumpkins plants. I bought and sprayed Neem oil on my plants today and will see how effective it is in a few days.

I have struggled with powdery mildew and downy mildew on any plant related to gourds here Florida. I have never heard of this treatment, so I am excited to learn of it. But I have questions. 1) Can you use powdered milk and water? 2) Does it work as a preventative measure. 3) Does it help with downy mildew?

Good Morning, Miss, On one of your videos, you show that you spray your plants every morning to help prevent disease and bug damage. What is the spray mixture that you use and the name of that video so I can watch it again. Thanking you in advance for your loving generosity to all gardeners.

Thanks, great tip. I have this powdery mildew for the first time ever! 😞💚

I like to apply a milk-water spray to foliar feed calcium directly to the stomata of the plants. I use a much stronger mix of 1-2 parts water to 1 part milk....

Thank you so much for nice informative video from🇬🇧❤️

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.

My rosemary plant has PM and I will try your tip…thank you!

Hi Kim, I just started seeds from your late summer collection. My cucumber and zucchini have the Powdery Mildew on about half the plant. Another issue, is my son is allergic to milk and we don't have it in our home. Can I use a milk replacement, like almond milk? It has protein in it, but it is the nut protein. If that wont work, do you have another organic recipe? FYI internet people- her seeds are awesome, all seeds I purchased have become seedlings so far, and have grown bountifully! Thank you Kim for all you do on the videos and seed propagation!

Thanks a lot I'm going to spray my garden got mildew on my planting garden too

we will try this on our cucumbers

I really appreciate and admire ur way of explaining love 💕👍also wants to know from where to get that spray bottle please

I use this spray on my lime trees works great

I let my zucchini get to war club size, then we bake stuff them w/burger & taco seasoning (chopped jalapeno's) & cheese. Lots of cheese. Yum!!!

Just milk and water makes a pesticide!.... Thanks for all tips of what time to spray

Of course I had power moldy problems but lost the plants for knowing no fix. Thanks and I will try.

“Anti-bacterial effect” is a misnomer. You are trying to prevent the mildew fungus, not kill bacteria.

Thanks for such a simple solution! Loved it :D

Nice video. I didn't know aboat the milk/water blend. Thanks. Steen, DK.

In midwest that is called baby zukes. Stuff the big ones with ground beef and sun dried tomatoes. Worschester sauce

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.😁

To prevent disease, place yellow sticky traps in an upwind location early in the year. I place mine about 3 feet off the ground. It does not stop all problems, but sure helps if you tend to have a lot of problems with powdery mildew.

I found PM on my butternut squash vines yesterday and immediately cut off the grossly affected leaves which were all quite low down. I have four vines that I am growing vertically and so far the PM has not affected the upper leaves. The bed is up against the house and about 18 feet long. Although it is against a dark brick wall the bed surprisingly gets a breeze which is welcoming in our subtropical climate. I intend to use your 8:1 water to milk spray today so I will let you know how I go. I can't believe how fast these vines are growing. I do however have squash fruit that are browning, so if anyone can tell me whether I need to prune these off as well, I would be grateful. It is my first harvest and these are the first plants I check out every morning. Thanks CaliKim!

I generally use the tablespoon of baking soda mixed in a gallon of water with a couple drops of non detergent dish soap works great on my ganga plants

i use a paint sprayer for my recipe. high power and will knock off aphids at the same time. works great. look at the resell stores for a used paint sprayer.

Thanks for your video. Another technique that should work is using a field horsetail brew, since it has antifungal properties.

Thank you for this video😊have followed your advice game changer for me.

I got it bad on my peas this year. I pruned them off as it kept coming time and time again. I live on the east coast right next to plenty of water so it is constantly humid during summer. It also gets quite hot, so I wind up fighting off the mildew, the pests(which have gotten bad already thanks to a bad heat wave,) then critters(mainly deer and rabbits.) Our problem has been over the past two years where it will rain for like 2 weeks straight and then won't rain for 3 weeks. My peas still produced fine, but I didnt want it to spread to the other plants in that raised bed.

Thank you for the useful advice 💚

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.

love how you have veggies and flowers together. any tips what can i plant in shade garden? big thanks and greetings from Canada, Niagara.

Thank you for an easy solution ❤️

What about planting in that soil where you had plants with powdery mildew? Is there a prodicol for what and when to replant and are we suppost to treat the soil woth something?

Wow Kim those zucchini are huge!

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 🙏

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!

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

Thank you , i will try it out on my tomatoes.

I wish I had known this sooner.

My hedges look like a snow man every year love your vids thank you

Hi Cali Kim, can you tell me what kind of pretty yellow orangish flowers you have growing in your garden? I would love to grow them in my yard.

🎉 beautiful garden! Quick question, what kind of milk do i use? Long life milk or does it have to be another kind? Pls explain for me. Excellent video!

Great video. I am going to try on my fig tree... Thank you
