When are worm castings to far gone to use?
Our chickens have been getting our kitchen scraps so my worm bin has been very, very neglected. I think I’m going to discontinue my bin just because it’s simpler for me to give everything to our birds (including animal products). Is there a way of testing the castings, though, to make sure they’re safe to put on our garden? I know we have quite a few mites.
