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.
Other fall and winter delights are the fast maturing radish and the many colorful beets, rutabagas, and turnips. Protected by the soil in zones 5 and above and with the protection of 1â2 feet of straw down to zone 4, root crops are a great addition to the winter garden. CULTURE: For best performance, all root crops require a light, rock-free soil that has been dug to a depth of 10â18 inches.
