"Square Foot Gardening" (the book) is out in a recent edition (I picked up a copy for a relative's birthday). There's also "Cubed Foot Gardening" by another author. Both are (I believe) based on the French Intensive Method. I tried it a number of years ago, but my yard must have been a toxic waste dump or something, so I confine my gardening efforts to when I'm out in the country. :') Try it on a small scale first, with something you're going to eat for sure (three or four different crops), as you will need a lot of compost and/or compostable material. Each year you'll have more compost, and can expand your efforts.
Thanks....I've been looking at the official SFG website and getting some ideas. Beans and tomatoes are a good start for us. We're definately going to try it.
