A mulch is a layer of material applied to the surface of soil. Mulch is added to soil for many reasons including conservation of soil moisture, improving fertility and health of the soil, reducing weed growth and enhancing the visual appeal of the area. A mulch is generally organic in nature.
A good soil structure helps the excess moisture drain away. Most soil has some level of naturally occurring humus. Adequate soil humus holds moisture like a sponge, where your plants need it most. Humus is the completely decomposed rich black soil and provides a buffer to plants under stress. However, If you have a sandy soil, it may drain well but not hold moisture or nutrients. Whereas a clay soil holds moisture but has poor drainage so roots can rot if it becomes waterlogged. In dry weather, it can even crack! If you have soil with poor structure, it’s even more important to add organic matter “Mulch”.
There are two basic kinds of mulch: organic and inorganic. Organic mulches include formerly living material such as chopped leaves, straw, grass clippings, compost, wood chips, shredded bark, sawdust, pine needles, and even paper. Inorganic mulches include black plastic and geotextiles. Both types of mulch discourage weeds, but organic mulches also improve the soil as they decompose.
