PLANTING COVER CROPS - this "green manure" is grown for the sole purpose of being tilled into the soil to add organic matter. It will help keep moisture from evaporating, regulate the soil temperature, keeping it cooler in summer and warmer in winter.

What are cover crops and green manures?
Cover crops are used primarily to protect fallow (unused) soil. In the North, gardeners usually plant them at the end of the season so their soil is not bare over the winter.

Planting fall cover crops such as clover or winter rye, and tilling them into the soil in spring, also will increase earthworm numbers. Leaves spaded into the soil during fall soil preparation will be eaten by earthworms and enrich the soil.

If the idea of more planting is too much for you, harvest what you have left, and consider planting a cover crop or green manure crop.

A cover crop of annual plants grown to be dug into the soil at maturity to improve or restore its fertility. Most useful are some annual legumes. Legumes absorb nitrogen from the air and convert it to plant food. Rye grass is also used extensively.

Empty areas of the garden, where the crops have finished, should be replanted with either a fall vegetable crop, or a cover crop of clover or vetch to help control weeds.

The summer before starting the garden, Marcia killed the sod and sowed a cover crop of buckwheat. She keeps a jar of buckwheat handy and sprinkles seed wherever she has a bare spot in the garden from harvesting an early-season crop, such as lettuce.
