Kill Powdery Mildew With This Natural Garden Remedy: Hydrogen Peroxide

In today's video, I teach you how to kill powdery mildew with this natural garden remedy: hydrogen peroxide. This is a completely natural remedy that can kill garden diseases and fungal infections and is great for disease prevention, too.
Hydrogen peroxide can be used as a garden disease control agent to treat squash, cucumbers, tomatoes, peppers, and other disease prone plants. I use hydrogen peroxide for plants to control diseases on my tomatoes all summer long, too! It's a key ingredient in my natural remedies as a garden fungicide.
If you have questions about how to use hydrogen peroxide in your garden for garden disease control, are interested in other garden remedies, want to know about the things I grow in my garden, are looking for more gardening tips and tricks and "garden hacks" like this, have questions about vegetable gardening and organic gardening in general, or want to share some DIY and "how to" garden tips and gardening hacks of your own, please ask in the Comments below!

40% Milk + 60% Water also does wonders for killing Mildew at least for me.

[@2MinuteGardenTips]

There are a lot of remedies out there to kill fungi. If it works for you, keep using it I say.

[@Wolf-xu1fj]

@@2MinuteGardenTipswhat about baking soda in water ?

[@centscents]

@@Wolf-xu1fj This one does not work for me.

[@centscents]

It is another solution. Will try it. Thanks.

[@autumnkim4521]

Trying this on some plants I planted recently! Crossing my fingers this works! 😭

[@DebrasBeautifulMusic]

Hey neighbor! Thanks for sharing this. I found this out just by testing different things and want to share this: non-diluted 3% Hydrogen Peroxide is an excellent weed killer. I sprayed the top of our septic tank and all the grass and weeds died on it by the next day. I did not overly saturate it either. It is a better alternative to poisonous Roundup or other poisonous herbicides. A few months later the grass has already covered it again.

[@2MinuteGardenTips]

There are many uses for peroxide beyond medical uses. It's a great anti-fungal. Yes, it will kill weeds, too (so will white vinegar - another natural weed killer). It's also an excellent vomit-inducer. We had an incident where Dale ate an old onion in the compost pile. If you take a turkey baster, you can shoot a little hydrogen peroxide into the throat and they'll vomit within 60 seconds. It can be a lifesaver for pets if they get into something. The good thing about peroxide is it quickly disassociates into water and oxygen gas, so it leaves no residues. It's a great color-safe stain-fighter, too. I have used baking soda and peroxide to get stains out of clothes.

[@joeldavis2154]

Thank you so much! My squash had this exact same powdery fungus when it was late in the season and I had many squash close to harvest. I was devastated because it came outta nowhere and suddenly. I always have a bottle of peroxide in my house and it is and easy solution.

[@kathyash1000]

Thank you so much, struggling with powedery mildew on my tomatoes and butternuts and pumpkins. I am in South Africa. Going to do this tomorrow evening! I have 10 volume H202 which I have worked out to be 3%. Very informative video, I have subscribed!

Great information and a cheap remedy for mildew. A most for 2022 spring and summer gardening. Need to put it in my notes. Thanks for the info. As always very well presented.

[@2MinuteGardenTips]

Thank you! It is also very effective at preventing, controlling, and outright killing blight and leaf spot on tomatoes.

[@matytj5738]

I'm going to try this. Most of my roses in the back have powdery mildew for months and I've tried other home remedies and it works for a few days and it keeps coming back even though I treat them every day. It has stopped my roses from blooming.

[@Katiescorner15]

Hello, does this work on downy mildew too? I have some coleus indoor plants that got it and trying to combat it. I'm also worried it may have spread to my other indoor or outdoor plants. Would the ratio be the same for a preventative measure? Thanks.

[@2MinuteGardenTips]

Thank you! Let us know how it works. It usually takes a few treatments. Always apply at sunset so it can sit and kill the fungus without the sun drying it up.

[@kino7539]

For a small indoor spearmint plant how often should I spray it?

[@RetroBerner]

Good stuff, I was getting worried about my weed plants. Thanks!

[@drew-shourd]

Works great on cannabis, zero residue after also...

[@DiamondTrailRanch]

IS this safe to use around Yellow Squash that's flowering already? Thanks!

[@madetv1647]

I've been using 16 Tablespoons to a Gallon, and it seems to work a little better for me... I might actually try working it up even further, as my current results at 16 are not quite satisfactory either... Just wonder what will happen once I hit that Max Peak the plants can tolerate?? I think I'm going to use a few plants as experiments and try hitting them with Strait 3% Peroxide and see what that does as well... 🥰🥰

[@thenaturalhuman9568]

Wow this actually worked..

[@2MinuteGardenTips]

I wouldn't lie to you 😀 The best part is, it works even better as a preventative. You can spray this 1-2 times a week to ensure the plants never get a significant infection, and since it's basically just water in the end, you can spray it without having to worry about bad stuff accumulating in your soil overtime.

[@kennethlatimer4607]

Trying again my friend. Thankfully it is cooling a little in southwest Florida. I get 10 % of my seedlings to maturity due to mold fungus and pests. My chickens dont help either. I am on the h2o2 wagon. Hug Dale!

[@2MinuteGardenTips]

Hydrogen peroxide is an *excellent* preventative. When our rainy season starts, I spray 1-2 times a week at this concentration with my ULV fogger. It definitely helps extend their lives about another month or so. Eventually, the rains can get so bad that they succumb, but this year, my two original cherry tomatoes are still alive and producing that were planted in March! Now's probably the time for your garden to come alive with your much more pleasant and drier weather.

[@gwenbush6184]

Question - I saw a video about this working great but it noted a down side and said that it will also kill all the good microbes in your soil. Do you know anything about that?

[@serendipitymoments4684]

Very timely tip...I have zucchini and cucumber plants with mildew I noticed few days ago. I will use the hydrogen solution you've shared. Thanks! New friend here from Texas, USA 🇺🇸.

[@2MinuteGardenTips]

The cool nights of the fall spread the mildew. This should help cure it after a few applications. Let us know if it works!

[@serendipitymoments4684]

P Mildew has my Canada Crookneck Winter Squash under attack.Even though its end of season here in MN.I'm going to spray the leaves a few days prior to vines removal prior to destruction since the P Mildew lives in the soil..I'll use the spray much sooner in the growing season next year..Thanks for tip..Dale's such a good boy Peace from MN

[@2MinuteGardenTips]

Powdery mildew becomes more of a problem in cool, damp nights in fall, so I’m not surprised. It wasn’t an issue for me in the summer when it was hot, but I guess the UV index has fallen enough that it is no longer sterilizing the leaves. Let us know if you have success with the spray! Dale says hi.

[@Mark4WorldPeace]

[@carmellayates2503]

Thank you , I really appreciate this tip , I tried growing cukes first time this year and I only got 5 cukes out of 2 plants the mildew killed them really fast . Gardening here in Florida is so different , I never had these problems up north. At least now I know what killed them . I'll be ready if this ever happens again .

[@kennethlatimer4607]

Welcome to combat gardening! Southwest Florida here. Always have plants for backup because so many die due to disease and pests. It is not for the faint of heart.

[@2MinuteGardenTips]

I can relate. While my conditions aren't exactly like yours, the summers here are just too hot and wet, so we have to garden mostly in the shoulder seasons. July and August simply kills all the annuals except for the sweet potatoes and peppers...but even the peppers get stressed out. Hydrogen peroxide makes the spring plantings last longer, for sure.

[@2MinuteGardenTips]

I've learned that as well. I didn't realize how much easier gardening is in PA and NJ 😂 The biggest reason why I moved down here was the longer growing season, but it came with so many more challenges to get those extra 2 months of growing.

[@living9377]

Thanks for posting this! Great video and cheap solution 😄👍💯✌️

[@PrettyIndependent1]

Does it work as a natural pesticide too?

[@2MinuteGardenTips]

I doubt it. It won't be strong enough to harm most insects, especially hard-bodied insects.

[@luiginafacci401]

Wath about grape

[@pryan2168]

What is the solution as a percentage mix?

[@ChefNutter]

12.5 Tablespoons of HYDROGEN PEROXIDE to 4 Liters of water.

[@oftin_wong]

Sulphur dust is also completely natural ...and elemental And relatively cheap

Where can I read about that fogged? Thanks

[@2MinuteGardenTips]

It is linked in my Amazon Storefront in the video description. I have a video on my fogger here: kzbin.info/www/bejne/j4fKdJmNgbdsl6M

[@Wolf-xu1fj]

what about baking soda in water ?

[@2MinuteGardenTips]

I haven't tried it. Baking soda is very alkaline and salty, and I don't like the idea of so much salt and high pH running off into my soil. Hydrogen peroxide breaks down into water rapidly, so it's a very clean product.

[@EDDIEGARAGE]

once, pound, gallon, quarters no good in a country like Australia, metrics

[@linnealanderdahl4310]

Im a beginner plant mom, i thought it was pollen!! Then i realized, no flower no pollent (its a mint plant)

[@2MinuteGardenTips]

Cucurbits are very susceptible to powdery mildew. Any squash, melon, cucumber, etc. can get it, along with other species prone to fungal diseases.

[@CptApplestrudl]

Desease? Mildew is a funghi, isn't it?

[@Sassy_Chihuahua]

I’m watching from Australia. Your measurement is so confusing!!

[@enufots4621]

Ok, I see the powdery mildew spots on the leaves. I sprayed with the hydrogen peroxide solution in the ratio as recommended. Now, why is it NOBODY ever show what it looks like when you spray the powdery mildew AND NOBODY ever show what we expect to see the next day or 2 or 3, etc.? Why? because a picture is worth a thousand word and because I like to know what it looks like when it's working! As far as I can tell, the next day i still see the white spots!

[@JohnJalas]

lol harsh fungicide then pulls out peroxide.
