You would be mistaken to believe that plants are harmed by hydrogen peroxide with a strong odor. Because this solution adds more oxygen to the air, it can actually benefit your plants. Hydrogen peroxide is, after all, H202. Extra oxygen is added to the roots of plants when hydrogen peroxide is applied.

This treats fungal development on the roots and speeds up the plants’ healing process. The fungal cell walls are breached by hydrogen peroxide, which kills the fungus and prevents more from developing. To ensure the solution is adequately diluted, mix one tablespoon of 3% H202 with one gallon of water. Should you be utilizing this mixture as a prophylactic measure, you should spray your plants once a week.
