Mypex is a heavy duty weed suppressant tried and tested weed control fabric preferred by professional landscapers, gardeners and the horticultural industry. It stops weeds for years lasting up to 5 times longer than other cheaper brands and is easy to cut and install. Simply cut an X shape in the membrane in the area where you wish to place your plant.
