How to Install Plastic Edging
Time Required: Under 2 hours
Because it is so flexible, plastic edging is the edging of choice for curving beds and borders. It is the most economical of the commercial edgings and the easiest to work with, too. But if you are looking for sharp, crisp corners, look elsewhere. Plastic edging can‘t handle it. And be sure to anchor the edging securely with stakes to keep it from popping out of the ground.
Dig a trench along the edges of the bed With a spade, dig a trench along the edges of the bed to a uniform depth of 3 to 4 inches -- enough to let the edging stand at least 1/2 inch above ground level. Dig straight down to create a vertical "wall" that will support the edging.
Trim strips of edging to length if necessary, with tin snips Trim strips of edging to length, if necessary, with tin snips. Or, cut strips to size with pruning shears, scissors or a utility knife. To make joints less noticeable, place them away from corners, sharp bends, and angles.
Join strips of edging To join strips of edging, slide a coupler halfway into one of the top channels. Pinch the first strip to hold the coupler in place and fit it into the second strip.
