DeWitt Professional Weed Control™ 30 Year (formerly branded as DeWitt Weed Barrier™ 12 Yr.) is an easy-to-use, environmentally safe 3 ounce fabric that controls weeds before they start. Its unique design provides several advantages over conventional weed barrier products.
It is fabricated using a spun-bond 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 unraveling and makes the material easier to cut. In addition DeWitt Professional Weed Control™ 30 Year is hydrophilicly treated, providing improved water and nutrient flow through the fabric.
