Creating a definitive line between the lawn and garden areas adds a finished touch to the landscape. Gardeners use lawn edging to limit grass growth on garden edges. A host of lawn edging options exist to suit any budget or preferred design. Lawn edging also provides transition between each aspect of the property. Lawn edging ideas to keep grass out include manual trenching, plastic borders, pavers, bricks, landscape timbers and preformed wooden block edging.
One of the cheapest ways to create a beautiful border involves a shovel and hard manual labor. A trench edge border slices deeply into the grass edge to shear off grass in a straight line around the garden perimeter. Cutting this trench at a 45 degree angle limits the collapse of the edge of the trench. Landscapers use manual trench borders as a common edging option around trees bases, shrubs or flower gardens. This type of lawn edging requires regular maintenance to keep the line sharp and to catch persistent grass. Gardeners often pull mulch layers into the trench to further discourage lawns from invading garden space.
Plastic Landscape Edging
Plastic borders come in lengths of up to 20 feet. These products feature 6-inch wide, heavy-gauge plastic with a rounded lip. The lower portion of the edging material is thinner to allow for easier installation in the ground. Plastic edging works blocking grass up to 5 inches underground to effectively form a barrier between garden and lawn. This edging comes with metal stakes to secure the product in place and requires the digging of a narrow trench for installation.
Pavers refer to any edging material preformed as a square or rectangular preformed concrete brick. Pavers can stand alone, be used at an angle, on edge or placed completely flat on the garden edge to create a barrier to grass infiltration. Installation of pavers requires digging and leveling of a trench to accommodate a portion of the paver. Stack pavers to create a low retaining wall or place each brick flat to form a wide barrier between grass and garden areas.
Bricks offer great versatility in the landscape with strong construction and a host of potential uses as a lawn-edging product. Like landscape pavers, gardeners can use bricks at virtually every angle to create a unique edging design. Bricks landscape edging does require digging a trench, leveling the area and careful placement of each brick. Some individuals choose to fill gaps with coarse builder's sand to limit shifting of the landscape edge.
Manufacturers produce multiple types of sectional edging for easy installation along garden edges. Material includes concrete blocks with rounded tops in 1-foot lengths as well as individual wooden blocked wired together in sections. Both require digging shallow trench to secure the barrier in place. Use of these prefabricated products along an extended length of garden requires the tight placement of each section to keep grass out of the garden plot.
