Faux stone edging comes in a variety of materials. Vinyl and plastic faux stone edging provides the least expensive option, but quality varies. The edging typically consists of narrow panels molded to resemble stacked stones. The edging panels may break easily, depending on the quality of the plastic. The edging may not have the look of real stone, and it won't age in the same manner as stone. Concrete stone edging provides a more durable and realistic faux stone option. The concrete is cast and stained to resemble stone, but the edging is lighter and less expensive than real stone. This edging weathers and supports moss growth, like real stone, which may make it a more attractive option than many of the plastic stone choices.
Use faux stones anywhere in the garden where you would use real stone edging. The lightness and cost effectiveness of the faux stones allows you to edge a greater area than you could with real stones. Faux stones give garden beds a neat, finished edge while preventing nearby lawn grasses and weeds from encroaching on ornamental plants. Edging also allows you to elevate the bed around the surrounding lawn, creating a focal point. Faux stones lend a natural look to the edged bed so they blend attractively into the rest of the landscape design.
The installation method depends on the type of faux edging. Outline the edged area with twine or a garden hose before beginning the process so you can correct any mistakes in the shape of the bed before digging. Plastic and vinyl stone edging typically comes in panels. The panels have built-in stakes or holes to insert stakes to hold the edging in place, along with an undecorated skirt to be inserted beneath the soil line. Dig a trench as deep as the skirt on the edging, which is usually about 2 to 3 inches. Insert the edging into the trench and drive stakes through the holes, if applicable, before refilling the trench. For concrete faux stones, line the edge of the bed with them as you would real stones. Use mortar if desired.
Concrete faux stones require minimal care. They withstand the elements well and require only an occasional water rinse to remove mud or dirt buildup. Trim the grass near the edging carefully, especially if you use plastic faux stones. Mowing over the edging can break or damage the plastic. Cutting a narrow trench in front of the edging prevents grass and weeds from growing against it, so you don't need to mow too close to the edged area. The trench also provides an additional barrier so weeds and grass don't cross over or under the faux stone and into the garden bed.
