Mis forMulch
Mulch is a layer of material that you put on the ground around plants. Mulch keeps the soil from drying out, and can help keep it from getting too hot or cold.
Mulches can be made from many things, but the most common kinds of mulch are decorative gravels, pebbles, bark, wood chips and leaves. Mulches made from bark or leaves will slowly break down and make the soil better.
