Potted plants are susceptible to fungus when potting soil is kept wet for long periods of time. Wilting leaves, discoloration and rot are all signs that your potted plant is infected with some type of fungus. 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.
Clean a medium-size bowl or cup with boiling water.
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
Pour the solution into a clean spray bottle.
Spray the leaves, stems and buds with the solution. Be sure to spray the underside of leaves as well.
Apply the mixture directly onto the soil. Use your spray bottle to cover the surface with the solution.
Repeat process 1 to 2 times daily until fungus disappears.
