What to do with old container soil?
I live in a very small suburban yard and must use containers for my vegetable "garden". What can I do with the old soil in my containers (from last year)? I see they have a lot of roots in them but are pretty compacted now after winter.
Can I revitalize it somehow? Should I get rid of it? If so, what is the best way to do this? Our community's yard waste pick up program specifically says "no soil/dirt" and my own yard is so small, I don't have a spot to dump or spread the extra soil.
Thanks in advance!
