Used Potting Soil

Question

When I have removed my tomatoes, which have been grown in pots, is there any use for the soil or should it be thrown away?

Answer 1

You can compost it or put it out in outdoor beds. Some people will sterilize it and then add new fertilizer and use it again. Here is information on how to do that: https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/sterilizing-soil.htm
