How to Sterilize Potting Soil With Hydrogen Peroxide
Adding a sterilizing agent to potting soil can help to reduce soil-borne diseases and control pest infestations. Hydrogen peroxide is a natural, non-toxic sterilizing, disinfecting and oxygenating agent which is readily available. Here are step-by-step instructions on how to use it for sterilizing potting soil:
Steps for Sterilizing Potting Soil with Hydrogen Peroxide
- Gather the supplies. You will need a container or bucket in which to mix the soil with the hydrogen peroxide solution, hydrogen peroxide, a measuring jug and a stirring stick.
- Mix the solution. To make the hydrogen peroxide solution, mix one quart of 3% hydrogen peroxide with each gallon of water. Measure out the ingredients using a measuring jug.
- Soak the soil. To the solution, add three gallons of moist potting soil. Stir the mixture until the soil is evenly saturated. Allow the soil to soak for at least an hour or more.
- Strain the soil. Strain the potting soil to remove any excess solution. Let the soil dry completely before use.
Tips for using hydrogen peroxide to sterilize potting soil
- Discard the solution once it has been used to sterilize the soil. Do not pour it down the drain.
- Avoid using hydrogen peroxide on soil that has been recently fertilized as it can kill beneficial microbes in the soil.
- Do not use hydrogen peroxide at concentrations higher than 3%. Higher concentrations can be harmful to plants.
- Do not use hydrogen peroxide on soil that is intended for planting directly into as it can be toxic to plants.
Using hydrogen peroxide to sterilize potting soil is an easy and effective way to reduce soil-borne diseases and control pest infestations. Follow the steps outlined above and use the tips to ensure your potting soil is safe and healthy for your plants.
