Query: Crumbles in weeks, useless, and leaves a mess

"6-year" in product description is a joke, at best. The parts exposed to full sun simply rot in about 6 weeks. Not only is it a pain to replace weed cover after the plants are already medium-sized, the degraded fabric crumbles into small pieces that are impossible to remove completely from a vegetable/flower bed. It is not made from a biodegradable material.
