DeWitt Weed-Barrier® 12 Year is an easy-to-use, environmentally safe fabric that controls weeds before they start. Its unique design provides several advantages over conventional weed barrier products. It is fabricated using a spunbond method, which sandwiches melt-blown material between two layers of spun material, forming a powerful 3-ply layer of weed protection. Plus, the fabric’s higher carbon black content provides superior light-blocking capabilities to protect against the toughest perennial weeds. The design also prevents unravelling and makes the material easier to cut.
