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.
Moss Varieties for the Garden. There are a few moss varieties that are especially popular for home cultivation. Sheet moss is very easy to grow and can withstand foot traffic, making it an excellent choice for a lawn alternative or breakup between paving stones. Ceratodon moss is also good between stones. Cushion moss grows up to form a ball-like structure that changes color from dry to wet, making it a good choice for a more moss-centric garden. Rock cap moss clings to stones. Itâs good for mossy gardens or accents on stones in flower gardens. Haircap moss grows relatively tall and looks like a tiny forest.
