Not only does it stop the grass, but by leaving the bed side soil back a little, it retains the bark dust from the lawn. I purchased the 6” rolled top galvanized edging. My husband and I installed it—he is 72 and I will be 70 next month. We have ordered more for some other troublesome flower/shrub beds. I would highly recommend this product. It is also AMERICAN OWNED and MADE!!!!! YAY! Go Coyote.
