Organic mulch is material that is applied to the surface of garden soil to protect plantings and improve soil structure. Mulch is considered organic if it is made of material that was previously living plant matter. Examples of organic mulch include shredded leaves, compost, and crushed corn cobs.

Mulch is simply a protective layer of a material that is spread on top of the soil.
