The Vevor weed barrier fabric is a heavy-duty ground cover designed to help block weed growth while allowing water, air, and nutrients to pass through the soil. Made from tightly woven polypropylene, it is suited for gardens, flower beds, patios, gravel paths, farms, and greenhouses. This 2-pack includes two 4' x 50' rolls for a total coverage area of about 400 sq ft. The fabric is easy to cut to fit different layouts and features green guide lines to help keep planting rows aligned. Its durable woven construction is built for long-term outdoor use in changing weather conditions.
