Can you reuse potting soil post-blight?

choci Feb 5, 2010 07:34 AM

Last summer, like many people, we got hit by blight in our garden. We've been growing our tomatoes in pots, and I was wondering -- can the soil from last year be reused? Obviously I wouldn't use it for planting tomatoes, but I am hoping I can spread that soil in my flower beds or something? I'd really hate to just throw that soil away... what a waste that would be!

Any advice would be appreciated!

    I may be overly cautious, but I would not re-use it for anything. I would prefer to take the financial and/or feeling wasteful hit from pitching the soil rather than recycling it, working plants in it for 6-8 weeks, and finding out it was a bad idea.

      You might be able to bake the soil. An hour in a 250 degree oven. If you have a lot of the soil, might just be better to find a grassy knoll somewhere and pitch it on.

        I dump all my stuff in the compost pile and add new every year to the pots.

          Pitch it! Don't add it to your compost or mix it in with new soil. In the future, bag up any leaves and vines and pitch them too. The blight overwinters and reusing, mixing the old soil with new, or in your compost can contaminate that and continue the cycle. Active compost piles may not get hot enough to destroy the spores.

          Here's some discussions from last season:

            Boy, I sure wouldn't.
