A surface layer of rotted leaves or manure spread on the ground to keep the roots of plants moist or warm.
A blanket spread over the bare surface of soil to block the loss of moisture and to discourage the growth of weeds. Most mulches are of such organic matter as manure, compost, straw, bark chips, etc, which eventually rot and add humus to the soil, thus enhancing its fertility. Inorganic materials are also used.
