Our Ground Cover is woven from 100% black polypropylene slit film (also available in white). The yarns contain 2% carbon black, used as an UV inhibitor and light lock. This product allows water to flow through the fabric, but prevents weed growth from penetrating through the yarns. The black ground cover has green marker lines spaced on 12" centers to aid in container alignment.
