Master Mark Dig-Free 20 ft. Plastic Poundable Lawn Edging creates an attractive scalloped edge for lawn and garden projects. Easy to install, with no digging required for installation. Simply slide each end of the interlocking edging together and install to the ground with a rubber mallet. Each edging piece is 6 in. tall and wide. Use the provided 90° coupler to help create the perfect border for your landscape edging, walkways or garden. The 6 in. height allows you to determine the best height for your edging to retain rock, mulch, pine straw or other bedding materials. For best results, we recommend that you install the edging 1.5 in. into the soil. For rocky or harder compacted soil, we recommend that you wet the area prior to installation. Transform your garden or lawn with ease using our durable, low-maintenance edging and enjoy a beautiful designed outdoor space with minimal effort. Color: Black.
