Veggies wrap around a central pathway in this garden, which makes working the beds a snap. Orient it so that the keyhole faces south; the larger plants (beans, tomatoes, and sunflowers) will be on the north side, where they won't shade smaller plants.
To prepare the soil, till it 8 to 12 inches deep, picking out roots and rocks as you go. Don't till the 3- by 7-foot center-access path (the keyhole); as long as the ground there is packed, weeds will have a hard time sprouting.
After the soil is well tilled, spread 2 yards of compost evenly over the beds and till again. Level the beds, which should form a 9-inch-tall, U-shaped plateau around the path. Rake the sides of the beds steep. Finally, spread 6 cubic feet of coarse ground bark or wood chips over the path to make an all-weather surface and to help keep down weeds.
