DeWitt Pro line is a 3 OZ fabric. Designed specifically for professional landscapers, contractors and garden centers, DeWitt Weed-Barrier® Pro is available in black and brown. There’s a color to fit every mulch or stone application. Specifically made as a landscape and garden fabric, DeWitt Weed-Barrier® Pro is hydrophilic treated for water permeability. Our complete line of fabrics is available in bulk sizes for larger commercial and residential projects. The 12ft is folded to 6ft then rolled on a core. When rolled out it will fold out to a 12 ft x 300 ft roll. Please cover this fabric with rock, mulch, etc to prevent biodegradation from the UV rays. Thank you
