I have a little garden that I put a lot of work into this spring. It produced lots of cherry tomatoes, cucumbers (the taste of a fresh one straight from the garden is so different than a store bought one!), yellow squash, and black eyed peas. We got a few weeks of torrential rain, followed by blistering heat, and everything died. Now I'm just waiting to start over with a fall garden! I'd like to grow broccoli and lettuce.
For gardening related online communities, check out GardenWeb and Homesteading Today, two other forums I frequent (Homesteading Today's forum is a wealth of information on self sufficiency, not all that different from the values of the primal community!)
