Soil Sterilization and Nutrients

Anonymous added on May 7, 2011 | Answered

I have some potting soil and a bit of sea soil. How can I sterilize (kill the mold, especially) it so it isn't wasted and I don't have to buy more? Will it have nutrients in it after the sterilization?

You can place about 4 inches of soil in a shallow, oven-safe pan covered with foil and bake for 30 minutes at 180 degrees F. to sterilize the soil.
