Abstract
Abstract An improved landscape edging is provided that comprises an elongated anchoring panel that has a plurality of hollow, molded projections extending from one or both faces. The interior of each projection is open on the opposite face of the anchoring panel, forming a concave soil socket that becomes filled with soil when the edging is installed in the soil. A trim member is provided along the top of the anchoring panel. Also provided are an extrusion method for manufacturing the edging, in which the projections and sockets are formed by molding the initial extruded form, and a method for using the edging of this invention, comprising excavating a trench, placing the edging therein, and connecting multiple segments of edging to one another.
