Mulch is a generic term for a ground cover that protects the soil. Organic and natural mulch helps with moisture retention, weed prevention and water loss due to surface evaporation. Covering your landscape with at least 1" of mulch helps provide the soil with the much needed protection from the natural weathering elements. The mulch will decompose over time, providing carbon matter and feeding your soil. Choose from a variety of mulch to match your garden aesthetics.
