The EasyFlex Decorative Adirondack No-Dig Landscape Edging Kit adds craftsman charm to any gardening or landscaping project. The black ornamental edging is flexible enough to use as a tree ring and the patented No-Dig L-shaped design eliminates damage from digging into tree and plant roots. An overlapping post system and interlocking anchoring tabs create seamless borders, eliminating the need for connector pieces. Unlike other decorative fence-style edging products, the 4.5 inch high edging has a built-in retaining section designed to hold back bedding materials and can be installed on top of landscape fabric to prevent weed growth. Simply clear the area of debris and align the edging to the shape of the bed. Slide edging pieces together so anchoring tabs overlap. Then use a mallet to pound the spikes (included) into the ground on each end of edging to secure. Proudly made in the USA, the edging kit includes (8) 15-inch wide x 4.5-inch high edging pieces and (9) 8 in. anchoring spikes
