Vegetables in Containers
If you are new to gardening and have never grown vegetables in containers before, we recommend starting with tomatoes and lettuce. There is NOTHING in the grocery store comparable to the flavor of a homegrown tomato, and lettuce is so incredibly easy to grow, everyone should have at least one container of each at home!
