Mulch
Mulch
Mulch (/mʌltʃ/) is a layer of material applied to the surface of an area of soil. Its purpose is any or all of the following: to conserve moisture, to improve the fertility and health of the soil, to reduce weed growth, and to enhance the visual appeal of the area.
Etymology
The term "mulch" comes from the Middle English word "molsh" meaning soft, beginning to decay.
Types of Mulch
Mulch can be composed of a variety of decomposed organic or inorganic materials. Organic mulches include compost, straw, grass clippings, wood chips, and shredded bark. Inorganic mulches include gravel, pebbles, and landscape fabric.
Organic Mulch
Organic mulch is made up of once living material such as chopped leaves, straw, grass clippings, compost, wood chips, shredded bark, sawdust, pine needles, and even paper. Organic mulches decompose over time and contribute to soil health. This can be a significant advantage over inorganic mulches.
Inorganic Mulch
Inorganic mulch is made up of man-made materials or materials that don’t decompose, or do so very slowly. Examples include various types of stone, lava rock, pulverized rubber, fabric, plastic, and other materials.
Uses of Mulch
Mulch is used in agriculture and gardening to protect the soil and plant roots from the elements, to provide nutrients, and to prevent weed growth. It can also be used to improve the aesthetics of a landscape.
