mulch

Definition

Layer of material spread on the top of the soil around plants. Loose mulches, such as leaf mold and compost, retain moisture, insulate roots, and can improve soil structure and add nutrients. Sheet mulches, such as black plastic and landscape fabric, suppress weeds and also conserve moisture.
