The easiest way to remove fungus from potting soil is to use a homemade solution on a daily basis. As potted plants live among you and your family, it is important that the solution is safe for children and pets.

Step 1

Clean a medium-size bowl or cup with boiling water.

Step 2

Mix one part hydrogen peroxide with 9 parts water. Start with a small amount (such as teaspoons or tablespoons) to test the solution's efficiency with your plants

Step 3

Pour the solution into a clean spray bottle.

Step 4

Spray the leaves, stems and buds with the solution. Be sure to spray the underside of leaves as well.

Step 5

Apply the mixture directly onto the soil. Use your spray bottle to cover the surface with the solution.

Step 6

Repeat process 1 to 2 times daily until fungus disappears.
