What's the difference between H2O (water) and H2O2 (Hydrogen Peroxide)?
Hydrogen peroxide (H2O2), occurs naturally in rainwater and acts as nature's cleanser. It oxygenates soil and bodies of water, is non-toxic and safe to use around food, people and animals.Adding itwhen watering your indoor plants, mimicswhatMother Naturedoes for outdoor plants every time it rains.
Hydrogen Peroxideis distilled water with anextra atom of oxygen. H2O means 2 hydrogens and 1 oxygen atom. The extra 2 in H2O2 means2 hydrogens and2 oxygen atoms, called hydrogen peroxide.

What is Hydrogen Peroxide used for?
In human health, hydrogen peroxide has been used at different strengths for everything from wound care to toothpaste and cleaning. For our plants, hydrogen peroxideis used by plant hobbyists and growers toprevent and treata range of nasties, while promoting better health, restoring ahealthier balancefor our indoor plants to thrive in.
In New Zealand the brand I use isOxygen Plus Hydrogen Peroxide 3%or 6% double-strength but for my international plant friends, look for 3% food grade hydrogen peroxide like Essential Oxygen 3%available on Amazon.
Howdoes Hydrogen Peroxide help plants?
The most common uses of hydrogen peroxide for plants includes:Eliminatesroot rotwhilesupporting growth ofhealthier roots.Eliminatesfungal infections. Treatsfungus gnatinfestations. Increasesoxygen, creating an environment that harmful anaerobicbacteria, mould, fungi and diseasesdislike,butroots love, supporting healthier plants and naturallyrepelling pests and insects.
How do you use Oxygen Plus Hydrogen Peroxide?
The dose depends onwhat you need to promote or prevent.Find the issue you need help with below to check the dose before use. Please note the rates below are based on usingOxygen Plus 3% for Plants. If using Oxygen Plus 6% you need to either halve the amount of hydrogen peroxide, or double the amount of water below.
*Please note some leaves are more sensitive to foliarspraysthan others, including Peace Lily and Orchids. Take the same precautions as any treatment applied to leaves. Either avoid spraying on plants withsensitive leaves, or always do a test spray on a couple of leaves 2 days before treating the rest of the plant when using Hydrogen Peroxide as a foliar spray*
Hydrogen peroxide to treat Root Rot
If caught in time, there is hope. H202kills the bacteria and fungiin the soil responsible for root rot, andrestores oxygento help remaining roots recover faster.Directions:1:1 ratioof Oxygen Plus 3% and water. Bottom water or top water sopotting mix is fully saturated.Avoid leaves(pouring at this strength on leaves can burn them).
Pests and Insect Repellent (including Fungus Gnats!)
Useduring watering for root pests:
For larvae andpests living inpotting mix: Wait until top layer of potting mix is dryand the plant needs watering. Mix1:4 ratio. 1 part Oxygen Plus 3% to 4 parts water (eg: 1 cup to 4 cups). Either spray or saturate soil by bottom or top watering as normal. Depending on the insect, adults may continue to lay eggs, sobest used in conjunction with treatment such assticky trapsto kill adultsas well(sticky trays available hereon Amazon if you're not in New Zealand). For Fungus Gnats, the larvae tend to concentrate in the top layers of the soil, so you can simply spray the top layer instead of fully watering.
For pests that live on andeat leaves: Mix1:1 ratio. Lightly spray the entire plant. Best used in a fine mistspray bottle. Spray only (do not pour on leaves). Let air dry out of direct sunlight. Always spray-test one or two leaves the first time, especially for sensitive / thinner-leafed plants, to check for a reaction.
To support healthier, faster root growth
H2O2 provides extra oxygento roots for growth and germination:
Tosanitise seeds: UseundilutedH2O2 3%. Put seeds in a container that can be sealed. Pour Oxygen Plus to just cover seeds. Seal and soak seeds for4 hours. Rinse with water.
Tospeed up germination: Mix30mlsH2O2 3% with2 cupsof water (ameasuring cupmakes it easy to get the right amount). Soak seeds overnight, then plant as usual.
Forplanted seedlings: Spray with H2O2 solution of 1 part H2O2 3% to 32 parts water (eg: around 30mls per 1 litre -measuring cuprecommended).
Forestablished plants: Mix30mls of3%per 1 litre of water. Bottom or top water as usual (water soil only, do not pour on leaves).
For Hydroponics and Aquaponics
Harmful bacteria present in hydroponic gardens thrive in water with low oxygen content. Used in hydroponics, H2O2 3% boosts oxygen and helps combat low oxygen found in warm, room temperature water. Mix 2 to 3 teaspoons to 3.7 litres of water. Pour over plants.
To treat Potting Mix before use
Disinfect organic potting mix to kill bacteria and diseases before use. Spray or sprinkle 1/2 a cup of H2O2 3% over the potting mix before use, until lightly damp, and mix in thoroughly before potting up. You can also mix 1:1in a spray bottle and mist the surface generously, so when mixed through the entire potting mix is lightly moist.
Toeliminate Fungal Infections
When the plant needs watering, flush water with a 1/4 cup of H2O2 3% with 4 cups of water. Water heavily until the mixture drips out the drainage holes and the soil is fully saturated. Make sure to tilt the pot as you go to cover all areas of potting mix.
To clean a Humidifier
Mix 1 part H2O2 3% to 4 parts water. Fill your humidifier and leave it to soak for 30 to 60 minutes. Rinse out, and leave to air dry.

Where can I buy Hydrogen Peroxide in New Zealand?
From me here at Love That Leaf :) I stock the Oxygen Plus 3% Hydrogen Peroxide which the doses and directions for use above is based on, and also the new Oxygen Plus 6% Double-Strength (for that you either halve the H2O2 dose above, or double the water).
Where can I buy Hydrogen Peroxide in the USA?
You want to look for3% food grade hydrogen peroxide likeEssential Oxygen 3%available on Amazon.
