Local Knowledge About Mulches And Coverings

Use a deep layer of mulch in planting beds to help retain moisture, slow weed growth, and prevent erosion. Mulch also recycles plant materials that might otherwise end up in the landfill. Organic mulches improve soil structure as they decompose and moderate the soil temperature, two factors that also help plants use water efficiently. The use of mulches on sloped areas along with terracing and plantings can help prevent runoff and erosion problems. Examples of organic mulch material include shredded bark, wood chips, pine needles, straw, pecan hulls, cotton seed hull, composted leaves, and shredded cedar. Use mulches from locally or regionally derived materials. Use inorganic coverings such as pea gravel, crushed granite or pebbles in unplanted areas.
