Can you “wash” your garden dirt from viruses and fungus

Question

I have a garden that I grew tomatoes in this season. They all got a fungus, except the grape tomatoes. I removed the plants and tomatoes. I want to know is there a way to clean the soil so I can use this area for planting again next season. Thank you.

In addition to rotating your crops, you may want to solarize the soil. This involves covering the wet soil with plastic and letting the sun heat it for a period of time. You can also spray the soil with a mixture of water and hydrogen peroxide. Here are two articles that should help with your sanitizing project:
