Natural lawn edging options include stone and wood. Stone edging can give a garden a formal look when cut stone is used or a rustic appearance with fieldstone. An ecologically friendly option for a tropical-themed garden is lightweight bamboo. As is the case with any form of wooden edging, the bamboo will eventually deteriorate if it is used in areas that experience extreme weather and may need periodic replacement.
Manmade edging can be fashioned from plastic, steel, masonry, brick or aluminum. Rust-free aluminum edging is available in 1/8- or 3/16-inch widths, and is easily installed around both curved beds and long straightaways when accompanying pegs are used to keep it in place. Masonry or brick edging can be expensive and more difficult to install around tight corners but is extremely durable. Polypropylene edging, a plastic product designed to look like stone, is available in light, interlocking pieces that require no heavy lifting or digging to install. Finally, steel edging, available in 10-gauge grade, is a durable option, but is subject to rust if it is chipped by lawn mowers or trimmers.
Edging that is installed flush to the lawn becomes invisible after the installation. This product is generally used in tandem with concrete or masonry pavers to keep the stone from moving laterally and to maintain a permanent edge for your lawn.
