Master Gardener 3-5/8" x 20' Black Yard & Garden Landscape Edging. This flexible, durable, and easy-to-install edging is made from 100% post-consumer recycled plastic, making it eco-friendly and long-lasting. It can be used to form straight lines or gentle curves, effectively blocking the spreading of grass and weeds while creating a neat border. Stakes are recommended to hold the lawn edging securely in place, and couplers and stakes are sold separately.
