 First, we prepare our soil as if we're getting ready to plant. And then we watered it in real well. After that, we take some clear plastic and lay it over the area on a very hot day. And it's got to stay there for about two weeks. So when you know that it's going to be 90 degrees or more, that's the time to solarize. After that time period, you take the plastic off and you let it cool down for a couple of days. Then you're ready to plant.
