Wooden landscape edging forms an attractive barrier in the lawn, separating flower beds or a particular section from the remaining area. Although edging made from a variety of material such as plastic, metal, stone, rock and concrete is easily available in the market, wooden edging has a natural look that blends with the surrounding area while forming a subtle decorative barrier. Installing wooden landscape edging is not a challenging task that requiring prior experience or a particular set of skills.
Spread powdered chalk or a garden hose over the area you want to edge. Keep lines as straight as possible if working around angular, rectangular or square beds. Measure the length to calculate the amount of wooden edging material you need.
Dig a trench over the demarcated line with a narrow shovel or hand-held hoe. Keep it 1/2-inch wider than the wooden edging board and 1/2- to 3/4-inch shorter in length so it slightly protrudes from the top. Collect the dirt in a wheelbarrow. Tamp the base of the trench with a length of two-by-four to provide a stable footing for the edging.
Lay an edging board in the trench to ensure the base is level. Add soil to any low spots and tamp it down.
Line the wooden edging boards outside the trench, and trim the length with a circular saw if necessary. Attach 2-by-2 stakes to the ends of the boards with 2-inch galvanised nails. Position the stakes an inch below the top of the boards before attaching. Also, measure and attach stakes every 4 feet along the wooden edging board.
Lower the wooden edging board inside the trench, with the stakes positioned outside the flower bed. Drive the stakes inside the ground with a sledgehammer. Make sure the edging rests level in the trench or push the stakes even further.
Add soil around both sides of the wooden edging boards. Tamp it down and rake. Add strips of sod over the exposed soil to cover it.
Use pressure-treated and rot-resistant wood for edging so it lasts many seasons and does not decay easily. For example, 40-pressure treated lumber is specially rated for ground contact and does not rot easily. Immediately treat any cut surfaces on the wooden board with sealer-preservative to prevent rot. Edge the particular part of your lawn with landscape timbers for a bolder look.
