The use of H₂O₂ also prevents root rot, which usually happens when roots are stuck in moist soil. Applying fertilizer made from hydrogen peroxide makes the soil well aerated. To boost the growth of your plant, mix 1 tablespoon of 3% hydrogen peroxide with 1 gallon of water, then use this formula occasionally. 

There are more ways on how to utilize hydrogen peroxide as a gardening input. This chemical compound also promotes faster seed germination. According to, it is also the extra oxygen molecule that softens the seed wall for faster germination. For 30 mins, soak the seeds in a 3% hydrogen peroxide solution then rinse it with clean water several times before planting.

Hydrogen peroxide can also be used as a pesticide. Through the foliar application, thoroughly spray the mixture of 3% hydrogen peroxide with an equal amount of water on plant leaves, fruits, vegetables, and even flowers. This method is effective in killing larvae of insects and bacteria settling in around your plants.

It is important to note that the use of a more concentrated hydrogen peroxide may kill your plants. 10 volumes or 3% strength of hydrogen peroxide is the most familiar concentration and usually the most recommended.
