Landscape fabric is a permeable material placed on the ground to suppress weeds, control erosion, and promote healthy plant growth. It allows water and nutrients to penetrate while blocking sunlight from reaching weed seeds, thus reducing the chance of weed growth. Landscape fabric is commonly used under mulch, gravel, or in garden beds to help reduce the need for weeding and maintenance. It is available in a variety of weights and materials, including synthetic and biodegradable options.
