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.
The benefits of mulching with these organic materials discourages weeds and garden pests, conserves moisture in the soil, keeps dust from blowing around, dresses up the beds with texture and color, improves topsoil as it breaks down, and it is a layer of protection for plants against weather.
