compost in containers?
Background: Tomorrow is the plant sale a my local community college, and they will have student grown native/drought tolerant plants - and they will also have lots of heirloom tomatoes, among other veggies and herbs.
Now, I won't be able to have an extensive garden this year, just a few things in containers. They are giving away free mulch/compost.
Will it be okay to use this in the containers as the sole or at least primary growing medium? or should I be using mostly potting soil with a touch of the composty mulchiness ?
