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.
It is tough to develop cover when cattle have access to the area. Most new crops that would be used for cover, such as native warm season grasses (switchgrass, big bluestem, etc.,) are all very palatable to cattle, especially when they are just established. My favorite cover is a blend of switchgrass, big bluestem, and little bluestem.
