Weed barrier cloth is a geotextile composed of polypropylene (or on occasion, polyester) with a meshed texture similar to burlap. These are both types of weed barriers with ‘weed barrier’ being a brand name that has come into common use for any garden weed barrier.
Attaining popularity in the mid 1980’s, garden weed barriers composed of these Geosynthetics are usually covered with mulch for not only aesthetic reasons but to also hinder the degradation of the fabric weed barrier from the sun and to help maintain consistent moisture beneath the weed barrier cloth.
This fabric weed barrier is used to reduce the amount of weed infiltration while still allowing water, fertilizer and oxygen to filter through to the plant, a definite improvement over laying plastic down as garden weed barriers. Fabric weed barrier is also biodegradable and resists deterioration from sun exposure.
