Keep your plants watered and unwanted plant growth at bay all thanks to the DeWitt Barrier Pro. Designed specifically for professional landscapers, contractors and garden centers, the DeWitt Barrier Pro protects your garden and encourages growth. This fabric conserves water by design; it's treated for water permeability. It lets water, air, and nutrients through and keeps unwanted plant growth out. To mask it, simply cover it with bark, mulch, or decorative stone. This garden fabric is brown and is a 4 x 300-foot refill.
