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 without dye. Most natural organic mulches will turn gray in about a year, depending on the amount of sunlight that hits them. However, if you want more color to accent the colors of your plants and flowers, buy custom-colored organic mulches (photos). They're processed with vegetable dyes in several colors.
