There's a great article in the April/May issue of Organic Gardening detailing how a couple managed to grow six months of fresh vegetables (about 800 lbs. worth) for around $75. In "Less Is More," author Sharon Tregaskis tells how she and her partner did it, relying on seed swaps, bartered labor, and shared tools to keep costs low and productivity high. Unfortunately, the article is not available on the web site (oddly, the In This Issue page doesn't even mention it in the list of featured articles), so you'll have to purchase the magazine to read it. But Organic Gardening is continuing to impress me since its latest makeover, so it's worth the purchase (or subscription!).
