Gardien™ WeedWeb landscape fabric is a traditional spun and point bonded black polypropylene non-woven fabric. This cost-effective fabric is designed to reduce maintenance requirements in gardens and landscapes by controling weed growth, soil erosion, and aggregate settling. The characteristics of WeedWeb fabric vary depending on weight (thickness): lighter, lower warranty grades have high water and air permeability to promote healthier plants, but offer less durability and weed control. Meanwhile heavier, higher warranty grades are more durable and provide better weed protection, but are also less permeable to water and air.* Gardien WeedWeb landscape fabric is available in 5 grades, ranging from a 5 year to 25 year warranty, and a multitude of roll sizes, so homeowners can choose the type and size of fabric that best meets the needs of their specific project.
