A diluted solution of hydrogen peroxide can act as a source of oxygen for plant roots, potentially promoting growth and combating root rot caused by anaerobic bacteria. Typical concentrations range from 3% (drugstore variety) down to 0.1% for regular use. For example, to achieve a 0.1% solution, one would add approximately 3 milliliters of 3% hydrogen peroxide to one liter of water. It’s crucial to understand that higher concentrations can damage plant tissues, so precise measurement is essential.
Oxygenation of the root zone is vital for healthy plant development. Healthy roots are more efficient at absorbing nutrients, leading to stronger, more resilient plants. Historically, hydrogen peroxide has been used in horticulture for its antiseptic and oxygenating properties. This practice has evolved from large-scale agricultural applications to become a common practice among home gardeners.
