A border serves several purposes in the landscape. The border prevents grass from spreading into the planting bed; keeps plant, mulch or stone in the bed and provides an aesthetic boundary between beds and lawn areas. An edge also gives the lawn and landscape a finished, manicured appearance. Installing a landscape border requires some planning, work and expense. When done properly, however, the border saves you working to keep the landscape and lawn attractive.
Select a border material. Small boulders and cut pieces of wood work well in a natural design. Bricks, formed concrete, metal and plastic edging function as borders in formal designs. Match the material to your home and landscape.
Mark the boundary line. Use a hose, string or spray paint where you want the border. Make the edge curved for a natural bed or straight in a formal landscape.
Measure the length of the edge. Figure how much edging material you will need based on the length. For example, a 12-foot border would require about 36 small, approximately 4-inch wide stones.
Cut an edge around the bed with a spade. Remove soil, grass and weeds. Make the edge approximately 2 inches deep. It should resemble a small trench.
Install the border material. For staked borders or metal, pound the border into the ground with a mallet. Arrange rocks, concrete and bricks to fit together. Place them one at a time and tap down with a mallet.
