Can I reuse container soil?
Every year I grow most of my tomatoes in the ground, but I've recently started growing some in containers. I had great success with my containers last year but the organic potting mix I used was a little expensive. Can I reuse the soil for a second year if I amend it? And if it's not good to use the container mix for a second year in the containers, can I incorporate it into my ground soil? I just would hate to get rid of it if I can still use it successfully. Also, what should I amend it with if I want to reuse it?
