I am aware that re-using material grown for tomatoes is not the best idea. I would hate to throw away what's in 20 containers. can I safely reuse this in my ground growing vegetables?
"Soil" used for tomatoes in e-buckets or containers
I would. Just use it for other none tomato family plants! Be sure to add some compost of some fresh potting mix to it and mabe a handful of green sand of if you can find it rock dust.
I agree- re use for the garden or raked over the lawn are fine.
