How to Use Hydrogen Peroxide in Your Vegetable Garden: A Full Experiment & MIx Ratios

How to Use Hydrogen Peroxide in Your Vegetable Garden: A Full Experiment & MIx Ratios

I show you how use Hydrogen Peroxide on your tomato plants and in your vegetable garden. I take you through 8 days of spraying, give you the mix ratios and show you the results. Always test spray before spraying all your vegetable plants. Use 6-8 tablespoons per gallon of water when you have a small outbreak. Use 10-12 tablespoons per gallon of water for larger outbreaks. Always start with the lower dosage in each category and work your way up. This ratio is for tomato plants.

    Thank you , it’s a big help for me as a beginner

  2. Luka Popovic on December 31, 2021 at 1:49 pm

    Is that dosage safe for all vegetable and fruit plants?
    Thank you

  3. teresa zetlein on December 31, 2021 at 1:50 pm

    I subscribed to your channel recently and am visiting your past videos. Thank you for your clear and thorough explanations and demonstrations, and for giving me extra tools to use in my veggie patch.

  4. William Latham on December 31, 2021 at 1:51 pm

    Gary great video my question is would you recommend using Hydrogen Peroxide on a lemon tree to fight diseases? if not what would you recommend? Thank You

  5. Prairie Adventures on December 31, 2021 at 1:54 pm

    Appreciate all your testing. Very helpful. I planted about 33 tomato plants, mostly all kinds of heirlooms in a row, only about18 inches apart, some even less. I’m hoping the H202 will take care of any fungal problems. If disease is taken care of, is that kind of close spacing ok? Do you still use baking soda spray, or just use H202?

  6. Takeshi Miyagi on December 31, 2021 at 1:54 pm

    is tomato a vegetable or fruit?

  7. Ed Albarico on December 31, 2021 at 1:54 pm

    What causes the tomato flower to wilt prematurely and not bloom. Also some of the leaves on other tomatoes are turning brown likely being burnout. Will that HydrogenPeroxide be the solution to my tomatoes?? I’m just a newbie into urban gardening in my backyard here in the Manila Philippines. Hope you can help me out.

  10. The Misplaced Country Girl on December 31, 2021 at 1:58 pm

    I am looking for your video about using peroxide on cucumber plants and cannot find it. Please help. Thank you.

  11. Robert Shorthill on December 31, 2021 at 2:02 pm

    Dr. Gary. The Serenade is probably used for squash powdery mildew, am I correct? I’m still not sure how it is spelled, but nursery outlets most likely will have it in stock, I again am assuming. Last year I had a good bit of PM and remedies were only temporary. I sprayed milk, soda and something else but that slips my mind at this time. I will try to find serenade for PM this year. Bob

  12. Takeshi Miyagi on December 31, 2021 at 2:02 pm

    LOL! you learned how to use hydrogen peroxide on your plants!

    I wonder if HP would work to help a tree get rid of beetles?

  17. SILVERTONGUE DAYWALKER on December 31, 2021 at 2:06 pm

    Hi my Darling hope you and your family are well. First time growing Toms this year. Some of our plants are in really big Pots
    I think we have put 2 too many in the big Pots.. Should of planted 2 plants in the big ones and not 4, we live to learn. . A few not many of the bottom leaves look slightly yellow. Some are curling up but other than that they look great. Just the yellow flowers out which we were happy to see. Growing Determinate for startets. I want to thankyou for all you do. ๐Ÿฅ•๐ŸŒผ๐ŸŒป๐Ÿž๐Ÿฆ‹ x

  18. danny s on December 31, 2021 at 2:07 pm

    Thx for your video, but i have a question, if i try to drench the soil with peroxyde for fungus gnats what is the dose for ideal ratio ? Thx again ! Oh last question does peroxide affect mycorrhizae?

  19. veronica belmontez on December 31, 2021 at 2:07 pm

    Gary, thank you for all the helpful tips and tricks for my garden. I literally stopped watching your other video on tomatoe varieties to click on this one and learned about Hydrogen peroxide. Finished spraying my squash and zucchini and hoping this helps. When should I see if it worked?

  20. Gibson Njeru on December 31, 2021 at 2:08 pm

    Thank you..and can this control pepper spots on snow peas?hydrogen peroxide

  21. Takeshi Miyagi on December 31, 2021 at 2:09 pm

    so if H202 damages the leaves and plant then why even use it???
    I used it on my pepper plant and it burned all the leaves off. I did use a diluted solution.

  22. Christian White on December 31, 2021 at 2:10 pm

    Just tested 6 tbsp in a half gallon sprayer on a small part of my ghost peppers towards the evening time. Letโ€™s see if it survives the night.

  23. Debie Gordon on December 31, 2021 at 2:11 pm

    Ur gardens are amazing Gary๐Ÿ Luv ur easy video too๐Ÿ‘๐Ÿ‘๐Ÿ‘ But what the heck do u do with so many tomatoes ?? and fruits?

  26. BLURRED GLASSES on December 31, 2021 at 2:16 pm

    Does it apply to all kinds of plants?

  27. Kay Lynn on December 31, 2021 at 2:17 pm

    will this harm my seedlings? I need to get rid of fungus gnats they are taking over my greenhouse and I think killing my seedlings

  28. diana burton on December 31, 2021 at 2:18 pm

    Love this video. Helps me understand fungus problems on my plants

  29. moddy harding on December 31, 2021 at 2:19 pm

    Help !! My squash plants looks great but the fruit is getting brown very small and then get mushy what do I do do I spray with hydrogen peroxide ?

  30. KENNETH HATHAWAY on December 31, 2021 at 2:19 pm

    Hey gary thanks for the video. I was wondering if you have heard of using milk for blight, fungus, mildews and soft bodied garden pests. I have read one University study where it increased production about 20% With 1 or 2 applications. More applications than that showed no further improvements My garden is much too small to do a definitive test. I have heard and read some very positive testimonies on its usage. Would love to see a complete work up on it, like is it the lactic acid? the milk fats? The sugars feeding the micro organisms? What works best 2%?, Whole?, Raw unpasteurized? powdered? I have used Whole milk on cannabis and roses. My results at least showed no damage and happier healthier plants at a mixture of 3 part water to 1 part whole milk I limited it to 2 sprays per year in fear of the milk fats blocking water and oxygen intake to the soil.. Does it work better for powdery mildew than hydrogen peroxide due to the fact that once the extra molecule of oxygen is released the remaining water is still there making it easier to get the mold again? Milk does give off the smell of milk gone bad the next day so for indoor use not recommended. It will also leave a whit residue which I am unsure whether that keeps the mildew from reoccurring till absorbed by the plant as food.. Also is milk even safe anymore with all the hormones and chemical additives? I would love to see results of someone I trusted like you. I am in no way affiliated with the dairy industry though I have had a fondness for milk from a very young age. Thoughts? possible future study? If it does all I have heard it is a garden wonder and usable to the day of harvest, readily accessible, hard to misuse and inexpensive

  31. Takeshi Miyagi on December 31, 2021 at 2:20 pm

    sulfur spray also burned my leaves and plants.

  32. Genghis Khan (PUREBLOOD) on December 31, 2021 at 2:21 pm

    Thats too little. I use half cup per gallon for foliar spray, 1 to 1 for watering to kill any fungus etc in soil is irraticated and oxygenate the soil

  33. Monique Hagans on December 31, 2021 at 2:22 pm

    Thank you for the info, can you use the peroxide as preventative before getting the powder mildew?

  34. Mike Davis on December 31, 2021 at 2:24 pm

    do you put hydrogen peroxide in the dirt ?

  35. Jeannette Loretta on December 31, 2021 at 2:24 pm

    Doesnโ€™t it kill the good fungi in the soil?

  36. EiDoDoos on December 31, 2021 at 2:25 pm

    Gary, please read this.
    this your video is very helpful for me to start doing experiment controlling fungi/diseases on my durian plant. i just got 50% concentration of h2o2 and i will find the exact amount of h2o2. i try 4,5 fungicide but the problem didnt go away. maybe because they are more into preventive control. . hope this h2o2 will work as curative.

    I used the 6 tablespoons of 3% H2O2 on my plants. It seems to be helping a bit on all of them except the eggplant. For some reason the eggplant alone was very intolerant to it, and the two leaves I tested on turned yellow and might be dead. Each plant seems to respond differently.

  39. Southern Patriot Council on December 31, 2021 at 2:26 pm

    Apple cider vinegar and water spray is something you can do every day without any possible burn, and Iโ€™ve found it is the best preventative, and treatment. Baking soda should be applied every week.

  40. J Baker on December 31, 2021 at 2:27 pm

    There are 16 tablespoons in one cup, in case that makes it quicker for folks to measure. 12 Tablespoons is 3/4 of a cup. Thank you so much for this video. I really appreciate benefitting from all of your knowledge and experience.

  41. Jeffrey Deutsch on December 31, 2021 at 2:27 pm

    Thanks a lot for sharing your research. I have couple of Early Girl Bush, a determinate as opposed to regular Early Girl, an indetirminate. The early blight is destroying them from the bottom up. I keep removing the dead branches and spotted leaves. The upper 2/3 look healthy and are full of fruit and flowers. If I dont stop the blight I will lose the plants. I have some Fung-onil in a pre mixed spray bottle. , which is Bonide’s version of Daconil. The manufacturer’s warnings make me very nervous about consuming the tomatoes and even damaging the plants. It says to use every 10 days but not more than 3 times. I will definitely try the Hydrogen peroxide tomorrow as a fast acting safer alternative. I read that the fungus is in the soil and gets splashed up when you water so they recommend that you mulch to act as a barrier. Besides, it is good practice anyway to keep the plants from going dry.

  42. Amous Anon on December 31, 2021 at 2:28 pm

    18% food grade is more efficient

  43. hokkanu on December 31, 2021 at 2:29 pm

    Could you please measure how much ml is 6 table spoons? The size of spoons can wary around the world and I’m afraid I can damage my plants. Thank you.

  44. Cape Flattery on December 31, 2021 at 2:32 pm

    I just found your channel and after watching two videos think you may have the best one on YouTube. I was also happy to see that you, like me, garden in Zone 7 in Maryland. I’m in Zone 7b, though it seems to have acted more like 8a in recent years. I’m fighting some tomato fungus issues and am going to test the 12 tablespoons per gallon method.

  45. munchkin5674 on December 31, 2021 at 2:38 pm

    What ratio do you suggest for cucumbers, squash, zucchini and melon foliage?

  46. Starchild11 on December 31, 2021 at 2:38 pm

    I use the peroxide a little higher strength. I spray a few days in a row as well and have started at any sight of disease. It really works amazingly…. Best tomato tip I’ve ever learned. Thank you thank you thank you. Used serenade before and it didnt work nearly as well.

    Many of the helpful bacteria work because they secrete peroxide. Full circle.

  49. Nora Reuben on December 31, 2021 at 2:42 pm

    How often i should use hydrogen peroxide for my plants and i have tiny white flies on each and every leaves …how do i treat this disease for my plants.???

  50. T D on December 31, 2021 at 2:47 pm

    Has anyone had a chance to try hydrogen peroxide treatment on rose leaves? Dealing with leaf spot currently.
