Abstract
Abstract A landscaping bed divider is disclosed for forming a boundary between adjacent landscaping areas and for preventing grass or the like from rooting between adjacent areas. The divider is formed as an elongated structure having an enlarged upper section, and a flange section extending lengthwise along the upper section and depending downwardly therefrom for insertion in the ground whereby the upper section is located above the top surface of the ground and the flange section forms a barrier between adjacent landscaping areas. Upwardly and outwardly diverging lips are formed integrally with the flange section intermediate the ends thereof for securing the flange section in the ground. The flange section is corrugated above the securing lips and is a plane section below the securing lips. The corrugations define vertical reinforcing ribs on the flange section, and the plane section below the securing ribs defines a lead-in portion to facilitate locating and inserting the divider structure in the ground. Preferably, the entire divider section is integrally extruded of plastic material.
