Abstract
The present invention relates to an improved extruded plastic elongated edging strip for use in gardening. The instant edging strip is particularly adapted for being positioned in the ground to separate growing areas in order to keep one type of plant on one side of the strip and thereby prevent an undesired comingling of plants. The subject edging strip includes a flexible thin upright wall which has a bead on one longitudinal edge. The bead is formed integral with the upper or exposed edge of the edging strip. The upright wall has a plurality of ears hingedly formed in the wall. The ears are adapted to extend away from the thin wall for engagement with the earth to hold the edging strip in place.
