A frenulum (or frenum) is a small fold of tissue that prevents an organ in the body from moving too far.
Cover crops usually are grown to prevent soil loss from wind and water erosion. Use fast-growing cover crops, such as winter wheat or annual rye, on fall-spaded gardens. A second, and probably more important reason home gardeners should use cover crops is to improve soil structure and increase organic matter.
Crops you can grow in clay soil include beans, chard, cabbage, rice and the root vegetables carrots and beets. Crops you can grow in clay soil include beans, chard, cabbage, rice and the root vegetables carrots and beets.
