Abstract
Abstract A landscaping edging material is described preferably made from a polymeric plastic material and formed having a planar face surface which is attached or integrally formed with a corrugated central web portion. The edging is placed on the ground surface or partially below the ground surface to delocate boundaries of lawn or garden areas or provide an effective landscape retainer to contain dirt, bark, chips, stones or the like in a confined area. The edging is retained in position by using a plurality of stakes which are inserted normally by hand into the ground through the elongated channels formed between the planar face surface and the central web portion. The stakes preferably have reverse loops that are then placed into an adjacent channel to add security and enhance the aesthetic appearance of the edging. A "hair pin" connector stake is employed to connect two sections of edging or the two ends of a section forming a circular pattern. In accordance with second and third embodiments of this invention, a corrugated material is employed having a pair of planar face surfaces separated by a corrugated central web portion. The edging of this invention is aesthetically attractive, cost effective, durable, easy to install without tools over any terrain, and can be readily formed to the desired border contour, and easily cut to size to fit any landscaping requirement. Additionally, the material provides excellent rigidity in the vertical plane and withstands impact from lawn mowers, trimmers, and the like. Additionally, the edging can be increased to width to various sizes enabling it to be placed in the ground to impede grass and plant growth, or to be used for fencing and wind breaks, etc.
