You don't have to be a homeowner with a yard to experience the joys of growing your own tomatoes. Urban community gardens are popping up everywhere, allowing city dwellers to grow their own food, and empowering low-income communities to control what goes on their plates. We dig into community gardening with Norma Anderson, who sits on the board of the Fox Point Community Garden in Providence; Steve Sheekey, volunteer coordinator at the GrowUp! Community Garden in Woonsocket, R.I., and Wendy Pires, garden coordinator at the GrowUp! Community Garden.
