Small Outdoor Space? Consider "Square Foot Gardening"

There's nothing quite so satisfying as growing your own food--and nothing quite so frustrating as being a would-be gardener with a too-small outdoor space. I have known this pain myself, so I was particularly intrigued when Dabney, our Projects Editor, told me about Square Foot Gardening, a very efficient technique for growing things you can eat. Could this be the perfect way to grow a lot of veggies in just a little bit of space?
