Keep your plants watered, weeds at bay, and toss out your herbicides all thanks to the DeWitt Weed-Barrier Pro. Designed specifically for professional landscapers, contractors and garden centers, the DeWitt Weed-Barrier Pro protects your garden and encourages growth. This fabric conserves water by design; it's UV and hydrophilic-treated for water permeability. It lets water, air, and nutrients through and keeps weeds out. To mask it, simply cover it with bark, mulch, or decorative stone. This garden fabric is black and is a 4 x 100-foot refill.
