Where can I buy heritage seeds?
Do you mean heirloom seeds? These are non-hybrid seeds that have usually been passed down from generation to generation. Check out heirlooms.com, or just search for heirloom tomatoes, and several types of vegetables will show up. Tomatoes are great to grow in pots, as long as they get plenty of sun. They are water hogs, though, so be sure to water them often. Also, I always use Miracle Gro for Tomatoes on them or on peppers or eggplant (all in the nightshade family). Any of these will grow well in pots, as well as herbs. Just about anything can grow in pots as long as the pots are big enough.
