How to Treat Soil Infected With Fungi

Oven Method

• 1

  Test the consistency of the soil. To withstand sterilization, the soil should be slightly moist, slightly crumbly, and free of large chunks of organic matter. If needed, sift out any lumps, and add a small amount of water to moisten.

• 2

  Set the oven to 200 degrees Fahrenheit.

• 3

  Spread about 4 inches of soil on a metal baking pan, and cover it with aluminum foil.

• 4

  Place the baking pan in the oven, and bake for 30 minutes. Periodically remove the pan and check the temperature of the soil. When the soil reaches 180 F, turn down the oven to 180 F, and allow the soil to bake for an additional 30 minutes.

• 5

  Remove the pan, and allow the soil to cool. Use the sterile soil for planting, as desired.

Microwave Method

• 6

  Examine the soil to see that it is slightly moist, slightly crumbly, and free of large chunks. Sift out any lumps, and add a small amount of water, if necessary.

• 7

  Fill a quart-sized container with soil, and cover it with plastic wrap. Poke a few holes in the plastic wrap with a toothpick to allow steam to escape.

• 8

  Heat the container in the microwave for 20 minutes, periodically removing it to check the soil’s temperature. When the soil reaches 180 F, heat it for an additional five minutes.

• 9

  Remove the container from the microwave, and allow the soil to cool. Use the sterile soil for planting, as desired.
