The gist of square foot gardening is this: You build an open bottomed box and fill it with a good planting mixture of soil and compost. Mark it off in one foot squares. In each square foot section, plant one herb or vegetable – a different herb or vegetable in each square. The smaller the plant, the more of them you can put in one square.
Since this is above ground, with new soil, there’s no need to “plow”. Just plant, plant lot of trees, flowers, fruits trees, herbal trees Etc. And because it’s above ground somewhat, it’s easier to get to everything without bending so much. When any given plant stops producing, you just pull it out and plant something new – while the surrounding plants continue on around it. For plants that usually take a lot of space by running along the ground, you go vertical with stakes or cages,check this out.
This method is especially good for areas of poor soil. Since you built the soil from scratch, it doesn’t matter if the underlying soil is clay or sandy or whatever (although you should probably put a weed barrier underneath it). And as you pull out a finished plant, you can add new soil or compost before you add another plant. And you continue to add new plants as older ones finish, all through the growing season.
So you can see that you’ll get a lot more vegetables out of this very small space than you would from a much larger “regular” garden. By the way, it will probably use less water as well.
Make the bed box small enough so that you can reach everything from outside the box. That way you don’t compact the soil or damage plants by walking through them. If you’re handy at building things, you might even put a “seating platform” around the top edge so that you can sit and work rather than kneel and work. This is a good method for people who have mobility problems as well.go straight to http://www.melbartholomew.com/what-is-square-foot-gardening/ for more info.
Sherry has two square foot boxes. The smaller one will have: three different kinds of tomatos, marigolds (companion planting) and …. to be decided. The bigger box is to have: peas, green beans, summer squash, onions, carrots, cauliflower, eggplant, a couple kinds of lettuce, spinach, sweet peppers, brussel sprouts, parsley, basil, bok choi, swiss chard, cucumbers, and a few companion flowers. And maybe a couple other things, too. That’s a lot of stuff.
