I have two raised garden beds that I have not really paid attention to since last October. Unfortunately, the neighborhood cats have decided to use them as their playground/litterbox. I knew I had a problem, but I didn't realize just how bad of a problem until I went to clean out my beds today. Everything I've read online makes me feel like I need to burn it all down and completely start over....which is maybe a little overkill. But maybe not? Any insights? And any insight as to what to do with a large load of contaminated dirt? #activity source
