EasyFlex Heavy-Duty No-Dig Landscape Edging is 30% heavier than most No-Dig Edgings. The 1.7-inch-tall commercial-grade edging creates a clean line between landscaping and grass to contain ground cover in garden beds including river rock, lava rock, pine needles, and wood or plastic mulch. Installing No-Dig Edging is simple. Clear the area of loose dirt and debris, lay the edging along the garden shape, pull the edging tightly, and drive the anchoring spikes (included) through the tabs with a rubber mallet. If tabs bend down when spike is installed, loosen the spike slightly to avoid waves in the edging. Easily cut the edging to size with garden shears or utility scissors. Typical installations will require one spike every 3 feet. Depending upon soil type and installation shape, additional spikes may be needed to secure the edging properly. Durable yet flexible enough to create tree rings, the patented No-Dig L-shaped design eliminates damage to tree and plant roots. Kit includes (1) 40-foot coil of lawn edging, (16) 8-inch spiral spikes, and (2) connectors, which can complete a 40 linear foot installation. EasyFlex No-Dig Landscape Edging is made of recycled materials in the USA.
