And if you work it or walk on it when it's wet, it compacts easily.
Compaction creates poor drainage.
And when that wet, sticky soil finally dries out, it can bake into clumps hard as rocks. This makes it tough for roots and seedlings to make any headway. Spread 2 to 3 inches of organic matter across your soil. Bark, rotted manure, leaf mold, peat moss and compost are good choices for organic ingredients. Next, till, fork or dig your compost and fertilizer into the top 6 to 7 inches of the soil.
