Mulch layering is the practice of applying multiple layers of organic or inorganic mulch materials over the soil to improve moisture retention, suppress weeds, and enhance soil fertility. Organic materials, such as straw, wood chips, or compost, are often used in the top layer, while other materials like newspaper or cardboard can be used beneath for extra weed suppression. Proper mulch layering can create a more sustainable, nutrient-rich growing environment.
