Mulching
Mulch is used to protect precious
topsoil and inhibit weed growth by covering the areas in landscapes
where the soil is exposed. As the organic matter in the mulch
decays, the released nutrients feed the plants and beneficial
microbes in the soil.
Mulch is typically a loose, fibrous material. The mulch must
allow rain and irrigation water to reach the plant roots.
Different Types of Mulches
- Wood chips
- Fallen leaves
- Grass clippings
- Compost
Benefits of Mulching
- Prevents erosion
- Suppresses weeds
- Retains soil moisture
- Cools the soil in the summer and warms
the soil in the winter
- Reduces fertilizer demand as the mulch
adds soil nutrients as it breaks down
- Saves diminishing landfill space
To use mulch,
apply a 3 to 6 inch layer around trees, shrubs, and within
garden beds. It is not recommended to pile the mulch up against
tree trunks.
