How To Use Food Grade Hydrogen Peroxide On Houseplants. Why Using Store Hydrogen Peroxide Is BAD!

Have you ever wondered about using hydrogen peroxide on your plants? But more specifically did you know there’s a difference between hydrogen peroxide that is food grade and regular hydrogen peroxide being used on your plants. The Gardening in Canada article is going to look at exactly what you should be using on your plants to prevent any unnecessary issues. Let’s jump into Hydrogen Peroxide Food Grade Vs. Pharmacy For Plants.
The short answer to whether or not you should use food-grade hydrogen peroxide over regular hydrogen peroxide on your plants is, YES. Food-grade hydrogen peroxide is a better choice.

Ashley is a soil scientist who has had a passion for plants since she was a small child. In the long summers as a child, she would garden alongside her grandmother and it was then that she realized her love for greenery. With years of great studying, Ashley had begun her post-secondary education at the University of Saskatchewan.
At first, her second love, animals, was the career path she chose but while doing her undergrad she realized that her education would take her elsewhere. And with that, four years later she graduated from the University of Saskatchewan with a bachelor’s degree in science and a major in Soil Science.
Some of Ashley’s interests are KZbin, in which she posts informative videos about plants and gardening. The focus of Ashley’s KZbin channel is to bring science to gardening in a way that is informative but also helpful to others learning to garden. She also talks about the importance of having your own garden and the joys of gardening indoors. Ashley continues to study plants in her free time and hopes to expand her KZbin channel as well as her reach to up and coming gardeners.

Highly recommend soaking roots in hydrogen peroxide before repotting when dealing with root rot. I did a side-by-side comparison with two olive trees I was rehabbing. Night and day, the one that got the soak bounced back MUCH faster.

[@charliblake8551]

Okay….firstly….you’re friggin AWESOME, I’m super into your vibe and I deeply appreciate all of the sciencey info! I have a question I’m realllly hoping you’ll have a second to answer. I’m only a few months deep into the terrarium hobby but I’ve fallen HARD and I’m wayyyyy down in the rabbit hole. Sterilizing/sanitizing etc is a huge thing as you are dealing with a (mostly) closed system. If something gnarly starts taking off in your terrarium/vivarium etc….it’s REALLY difficult to treat. I’m doing bioactive so I also have springtails and will soon have isopods so I have to consider those lil dudes. Don’t want parasites, mold etc. SO, when introducing wild collected moss it’s difficult to decide on the best way to clean it before it goes in. Of course I do a very thorough rinse job and will quarantine the?moss for some time so I can watch and see if any mold takes over or if it becomes infest by anything which hitched a ride. I was hoping to cut down on the quarantine part of the process a bit by doing a diluted peroxide soak. After watching your videos I’m now thinking it may be more detrimental to use peroxide than to risk introduction of outside contaminants. Do you have any opinions on this? Maybe if I use food grade it will be a less shady option to use? I realize that semi closed bioactive enclosures aren’t your specialty but give your knowledge on the more scientific end of things….maybe you can throw some educated guesses at me? Either way….again, I really really appreciate all I’m learning from you and think you’re generally pretty awesome! Cheers😊

[@OzRoller]

Great video! Thoroughly and well explained. I was actually looking for information about using 3% hydrogen peroxide in a hydroponic system, and this was the 2nd video I came across. Based on the info in this video, I see no reason why I shouldn't use it 👍✌️

[@MushroomMagpie]

Most drugstore peroxide is stabilized with AgNO3, Silver nitrate, which is rather safe. Some specialty products are now using Nano silver, but this is usually advertised as a selling point, even though in my opinion nanoparticulate silver is not a safe thing for the environment and has not been adequately investigated for it's effects on life. The only time I use peroxide on my plants is when occasionally adding enzymes to the soil as it helps to active them... apparently.

[@GardeningInCanada]

Yea it would work for that application because it would disturb the cell walls of the enzyme. So definitely a catalyze for them. The one thing I was torn on putting in the video because it’s so highly contested right now is the idea of seed germination. There is a theory that H202 increases germination rates.

[@lostpony4885]

"It is H2O2 and unstable" nice summary of my entire empirical knowledge on the topic plus how it smells.

I have used 3% Hydrogen Peroxide diluted in a 10 to 1 ratio for many years, but only as a mild pesticide or anti fungal (Only to treat and no more than a couple applications 3 days apart). Not sure about house plants, but in outdoor Bonsai works very well. 🙂

[@josecarloesteban2467]

Thank you so much for your scientific explanations! I love watching your videos, as I always learn something new from them. For killing off root rot with H2O2, in the setting of taking out the roots to soak them, would you still recommend food grade or regular H2O2? Furthermore, while we are on the topic of root rot, what is your opinion of ridding of all the soil-mix content once you find out you have root rot on your hands vs. just adding more aerating substrates (i.e perlite, coco chips, orchid bark) to the current mix to increase the oxygen content?

[@GardeningInCanada]

First off I’m so glad that you’re enjoying the channel. If you do find it useful and you think it could help someone else please feel free to share. Quite honestly most of my traction comes from you guys sharing my videos

[@GardeningInCanada]

What comes to killing off the root rot you can use the food grade and that’s what I do recommend. There is a ton of much-needed microbes in the rhizosphere of our plants and the H2O two hydrogen peroxide is definitely going to kill off those beneficial microbes. So when it comes to a soil having root rot in determining whether or not you should throw the soil out or simply add aeration. That added oxygen content is going to immediately kill any root rotting bacteria.

[@josecarloesteban2467]

@@GardeningInCanada is there any particular amendment (I.e perlite, orchid bark, coco chips) that you would recommend to add into your current soil mixture to significantly oxygenate your soil mixtures to battle root rot in soil?

I guess maybe I should try seeing if my springtails and opening the lids up to air out my terrariums periodically is enough to avoid mold takeovers. I know a little bit of mold is no biggie and even feeds my springtails. I’ve just also seen mold completely take over and murder everything else in a mostly closed bioactive set up.

Thank you so much for your fact based videos which are also hilarious. I really needed that chuckly this morning. I have a cane begonia that my mom left me when she died. It has been struggling with some sort of bacterial and or fungal infection. The only thing that seems to battle that off is peroxide. But now I am not happy about using it. Can you think of any other way I could eradicate the issue please? I will spray it with a solution of peroxide and water, and it will pretty quickly send out new healthy growth, then after a couple of months the center of the leaves will start to rot (it almost looks like) again, and it spreads to the center of all the other new leaves, very sad to watch. Any help with this guy would be greatly appreciated.

Hi Ashley. I'm trying to grow cannabis plants outdoor in 30 gal pots. I was going to use a rough ratio of 4 part sterile potting mix, 4 parts compost, and 2 parts drainage/ aeration. I'm trying not to use extra perlite because it's expensive and settles on top of the soil. The alternatives I thought I had access to was grit of native rock around 2mm thick, sand, lava rock(for BBQ 2" thick), woodchips or clay pebbles. Could I use a one of the above or a mixture of some to add instead of perlite? I was looking into pumice but it seems too expensive for how much I would need.

[@GardeningInCanada]

Yea dang perlite! That’s honestly the worst thing about it! I would even try adding coco husks & wood chips(keep in mind you will have some nitrogen robbing). The lava rock will work fine, the LECA (is my personal go to… )

Hi Ashley, re the last point about overwatering. How would you solve an overwatered plant? I have a couple I didn’t repot from the nursery soil and it was fine. But not with 6 hours a day of barely any light the soil takes 2-3 weeks to dry out for another watering and that’s a bit concerning to me. But on the other hand I’m not keen on the idea of reporting in December to amend the soil and drainage

[@GardeningInCanada]

I will do a video on this concept because i think it will help an enormous amount of people. GREAT question

[@TrinaMarie_Babygirl]

I don’t know what I’m doing so I use a lot of KZbin for my indoor and outdoor potted plants. When I’ve had issues with roots I would spray them wait a few minutes and then rinse with water. Chopping off dead roots before that. But with fungus gnats which is insane I’ve put a zap light in near my plants, a mixture of soap, water, sugar, and vinegar. That caught a lot. But I did use peroxide I bought at Walmart in a pray bottle on the top of the soil. A few squirts and added a small amount of water. Idk if it did much. I also poured cinnamon on the top of the soil and lightly watered. Careful not to get the leaves. Think some plants were ok with it some maybe not so much. If I think something is going on in the soil or roots I tend to get as much soil off and rinse roots and stick in water for a few days. Then decide whether or not to keep in water or make up soil and replant. I’m new to plants. I hate gnats they’re driving me nuts

[@618grow]

So checked my run off and my ppms are high. I need to run RO water to lower it I'm aware but am I better off doing it all at once or over a 2-3 waterings? I have high porosity medium 35-40% perlite in soil. Clones 4.5 weeks from rooting.

[@DragonflyenAmber]

I had wondered about this when I kept seeing it pop up in gardening groups and vlogs. It didn't seem like a good idea to put into the soil. Is it safe to assume that the stuff sold at pharmacies is NOT the food grade? (how would I know the difference?)

[@GardeningInCanada]

Yeah so the stuff in the pharmacy is not food grade. There are several different stabilizers inside of those. Most commonly is silver nitrate or nitrate I can’t quite remember. So I didn’t include a link in the description and in the comments for a food grade option of hydrogen peroxide. Now keep in mind if it is at a grocery store it does need to state food grade on it. My understanding is that it’s not very common to see food grade hydrogen peroxide in an actual retail store. Mostly because it is not 100% shelf stable. It does have an expiry date on it which makes it less than ideal for storing in a medicine cabinet.

[@DragonflyenAmber]

@@GardeningInCanada Awesome thanks! I do have some in the house, but I'm sure it's not food grade. Stuff like that is required to list other ingredients in Canada isn't it? Mine only says sterile water under 'other ingredients'

I think the trees may have some sap suckers in them who poop on the plants below , causing sooty mold . Or , the trees are shedding a fungus themselves that’s spreading .

I agree that silver is a killer, but the free oxygen ? for me it is all about the amount of free oxygen which seems all the researchers ignored. How about 15 drops of food grade Hydrogen Peroxide per gallon of water ? just enough to make "bugs" happy but not enough to "oxidize" them to death : ) people would die from lack of some salt, but drinking two cups of salt in a gallon of water will kill us. Also, to me percolating oxygen in the soil for however short time is a very good thing in any soil.

my concern is that it gasses off. I just did a video on oxygen for plants and the uptake is via H2O not atmospheric

@@GardeningInCanada Yes, I watched that video, whether roots have no use for air is debatable in some circles ( many plants have so called air roots ), even so, "gassing off" is life giving for everything else living in the soil that needs breathing or else : smelly anaerobic mess. My favorite description of soil breathing is this : exhale - watering, filling all empty spaces with water, air out. Inhale - water out, evaporated , pumped out by roots letting air in.

[@stephanieserblowski2092]

I often hear hydrogen peroxide recommended for hydroponics to prevent root rot. Would a food grade ratio be safe for that use? It won't hurt the roots?

[@GardeningInCanada]

yup that would work in that application.

I put peroxide on soil to kill millipede, they are so nasty. Any suggestion on how to get rid of them when they live in your soil?

[@GardeningInCanada]

you should try getting a nematode product that will take them out. but keep in mind they arent all harmful some are benefical

[@mounag8518]

@@GardeningInCanada Thanks for the suggestion. I will get those nematodes

[@GardeningInCanada]

Yeah just do some research as to which ones you need. I know different companies sell different options. So for example the version I use which is called nemanights Has an ant formula, an indoor blanket formula, a slug formula that sort of thing

[@colly7963]

Millipedes don't normally harm your plants. They eat decaying plant matter.

Hey I need advice! I just used 3% hydrogen peroxide food grade 1 part water 1 part peroxide to get rid of bugs and mold in my house plant soil, have I just killed this plant or how I’ve only ever done this once will this be okay ?

[@GardeningInCanada]

It will be fine, I would not worry

[@youremamasofat4414]

I was a bit concerned about regular use on the leafs killing of beneficial bacteria , but for spider mites you usually use neem oil which is also antibacterial… Do you think food grade is essential for leaf treatment or regular would do just fine? Because I discovered that peroxide won’t kill the spider mite eggs so a weekly treatment is needed, and I’ve been wondering if it would do harm in the long run(without getting in the soil)

[@GardeningInCanada]

you could use regular. Have you tried predatory mites?

[@youremamasofat4414]

@@GardeningInCanada yes the problem is after a while they die off and the spider mites are returning , so it became a bit expensive… I think they usually return in less than two months after😞 Do you think non diluted 3% peroxide would be problematic in the long run?(only treating the leafs not the soil)

[@GardeningInCanada]

I don’t believe so no

What do you think of using colloidal silver in your garden? I always been against it. Which goes against so of favorite garden channels.

[@GardeningInCanada]

What context are they using it in. Are they using it as a soil amendment?

[@patkonelectric]

@@GardeningInCanada Don't know exactly. Not a KZbinr doing this. People in gardening chat rooms think it's a cure for all. One guy was going to water his plants with it. I talked him to do an experiment and water only haft with colloidal silver. I reach out to him latter on but he said that he abandoned his garden.

[@GardeningInCanada]

Oh that’s really interesting. It definitely would sterilize a lot of your soil.

[@cmleite]

Ashley, my plants have root rot from a Trader Joe’s plant that I reused the soil for cuttings. If I 1) remove the plant from the soil, treat with hydrogen peroxide + repotted in new soil 2) let the infected soil dry out + treat with hydrogen peroxide - can I then reuse the soil for another plant in the future? + Adding perlite and/or leca to increase aeration?

[@ruthmeow4262]

Hello. Adding perlite for aeration never hurts. My preferred sterilization method for potting soil is to dampen my soil all the way through and then bake it in the oven at 250F for a half hour. Kills most everything.

[@cmleite]

@@ruthmeow4262 thank you so much for the reply. I decided to pour hot boiling water x2 (outside) to avoid the smell of baking it inside because my apartment is not well ventilated.

Well crap I just bought 3%HP from the store because I’m having root rot issues in one of my plants due to too much rainfall last weekend outside on my deck but lucky I did not use HP yet. I’m about to take it back to the store. Seems pointless to use it and disappointment! Like how am I going to save my plants if the leaves crumble and looking frail. 😢
