I live in a new subdivision where heavy clay was used as backfill, and I just can’t get a good garden started. What will really break up the clay?
A. You can dig in fifty pounds of garden gypsum per one thousand square feet in the fall and in the spring. In the fall, cover the soil with a mixture of leaves, grass clippings, ashes, wood chips, builders’ sand and peat moss to a depth of six inches and sprinkle with fifteen pounds of garden food per five hundred square feet. Let this mix sit all winter. In the spring, spade or rototill very well into the clay.
