Is it possible? Are there Hydrogen Peroxide Uses in the garden? Well, yes, it can be useful! Read on to find out how.
How & Why Hydrogen Peroxide is So Useful
Hydrogen peroxide (H2O2) has an extra oxygen atom than Water (H2O), this extra oxygen atom breaks down and the molecule of water releases from this separately. It is this extra oxygen atom that makes the hydrogen peroxide so useful. The Hydrogen peroxide is used in cleaning, bleaching, sterilizing, as a disinfectant etc. but it can also be used in horticulture. In simple words, Hydrogen Peroxide acts as an oxygen supplement for plants (beneficial if used in low strength). It works by releasing oxygen and also aerates the soil.

Hydrogen Peroxide Uses
1. Hydrogen Peroxide Uses Against Root Rot
Overwatering causes the shortage of Oxygen at the root zone. If you overwater the plant, the water fills the air spaces in soil and the plant’s roots suffocate due to the lack of air and they begin to die after 24 hours. To save such a plant from this problem, water it thoroughly with 3% hydrogen peroxide mixed in 1 quart of water. The extra oxygen in the hydrogen peroxide provides the roots their much-needed oxygen to survive. After this, don’t water the plant until top 1 or 2 inches of soil dries out well.

2. Using Hydrogen for Faster Seed Germination
You can use hydrogen peroxide to help seeds germinate more quickly. Hydrogen peroxide softens the coat of seeds and kills any pathogen present on seed coat thus increase the germination rate and help the seed germinate faster. Soak your seeds in a 3% hydrogen peroxide for 30 minutes. Rinse the seeds several times with water before planting and plant them as usual.
3. Hydrogen Peroxide for Mold and Mildew
Hydrogen peroxide has an oxidizing property that is fatal for mold and mildew. Mix a liter of water with 10 tablespoons of 3 to 6% hydrogen peroxide depending on the level of infection. Spray this solution on plants daily until the fungus disappears.
4. Hydrogen Peroxide as a Fertilizer
Use hydrogen peroxide to help strengthen the root system of your plants. Hydrogen peroxide has one extra oxygen molecule (than water) that helps plant’s roots to absorb nutritions from soil more effectively, you can use this formula occasionally to boost the growth– Mix about 1 teaspoon of 3% Hydrogen peroxide with 1 gallon of water.

Caveat: Make sure that you do not use more concentrated hydrogen peroxide as it can kill plants. 3% strength is the most familiar concentration and usually recommended.
5. To Keep Pests Away
The hydrogen peroxide can be used as a pesticide. Spraying the plant thoroughly with 3% hydrogen peroxide mixed in the equal amount of water kills the pests and their eggs. The hydrogen peroxide also kills the bacteria that develop on fruits and vegetables.
