Re-using container soil - Diseases?

tam91 · February 17, 2011

In the past, I've dumped out the soil in my containers and sterilzed them each year. But as I'm wanting to increase the number of varieties, that's starting to be a lot of soil!

So I am wondering - which diseases can overwinter in the soil? I did pull out the plants and dispose of them.

I think I had some Septoria, could have been a little blight, and the strange un-named crud that affects black tomatoes. I was able to control everything with fungicides, and all the plants survived.

But - if I were to re-use my soil, are any of those diseases likely to be in there?
