Woven black polypropylene fabrics have excellent permeability to let air, water and nutrients through while blocking the light required for weed growth. Its the ideal choice for safe weed control and water conservation. UV-treated. Striped every 12 to aid in planting spacing. Sunbelt Weed Fabric is 3.2 oz/yard, and this high-grade fabric blocks 99.7% of light, and resists tearing, puncturing and weed penetration. It is approved for most government weed control applications. It typically lasts 8-12 years, according to the manufacturer who guarantees the product for 5 years against UV breakdown. The 6' x 6' size is perfect solution for controlling weeds around the bases of trees.
We used this weed fabric under a garden path with wood chips on top. It was contained between raised beds, so no problem slipping and we didn't have to stake it down. Works very well to stop weeds from going through the mulch. Light weight and thick enough so that it is easy to lay down. We will be using this again in our yard under pathways.Review by Debbie (on 10/31/13)
