Durable 3.2 oz woven polypropylene fabric provides the best of both worlds; white on top to reflect heat away from the soil surface and black on the underside to suppress weed growth. Resists tearing and weed penetration while still allowing air, water, and nutrients to pass through. Great for cooling the soil and conserving water. Ideal for cool-loving cut-flowers like sweet peas, lisianthus, snapdragons, and stock. Striped every 12 inches to aid in plant alignment and UV-stabilized to hold up to sunlight for multiple seasons. Secure with fabric staples or sandbags. Note: Although we found this fabric to be effective at suppressing weeds in our trials, it has a looser weave than black woven mulch and may not be appropriate for areas with excessive weed pressure. For areas with very high weed pressure, choose Sunbelt Black Woven Ground Cover.
