Mulch is a layer of material applied to the surface of soil in gardens and landscaping. It can be made from various organic materials, such as wood chips, straw, or leaves, as well as inorganic materials like gravel or plastic. Mulch helps retain moisture in the soil, suppress weeds, and regulate soil temperature. In addition to its practical benefits, mulch can enhance the appearance of garden beds and pathways. By breaking down over time, organic mulch also adds nutrients to the soil, promoting healthier plant growth. Proper application of mulch can improve the overall health of a garden or landscape.
