The square-foot method, in which you subdivide a raised 4x4-foot garden bed into 1-foot squares using a physical grid—such as lattice strips—is a specialized version of intensive cropping.
The square-foot method, in which you subdivide a raised 4x4-foot garden bed into 1-foot squares using a physical grid—such as lattice strips—is a specialized version of intensive cropping. You'll need 8 cubic feet of top-quality garden soil to fill such a bed with 6-inch-high sides. The planting formula is simple: 1 extra-large plant per 1x1-foot square; 4 large plants per square; 9 medium plants per square; and 16 small plants per square. Mix and match at will.
