Whether its made from pre-set bricks or poured from scratch, concrete garden edging provides a division between beds and grass. Edging also makes mowing easier; the wheels can travel on the edging, which eliminates the need for additional edgework. When laying your concrete edging, choose the location in advance to avoid adding a semi-permanent mistake to your yard.
Cut 8-by-6 foot plywood boards to a width of 1 1/2 feet using a table saw. Each plywood board purchased will make four boards for the project.
Press one stake every 2 or 3 feet where you want edging. Press them into the ground and tie a string to each stake to mark off the desired pathway of the edging. Make sure each stake is level with the previous one. Step back after you place the edging and verify that it is completely straight and matches your desired specifications.
Dig a trench that is at least 5 inches wide by 1 foot deep into the ground following the string guide.
Set up the plywood boards inside the trench to ensure a straight working space. With the boards in the trench, the edging will come out as 3 inches.
Mix the concrete in the wheelbarrow using the manufacturer's recommended amount of water.
Place the concrete into the trench, filling it so that the concrete is 2 inches higher than the ground. This will ensure that the edge will be flush with any grass.
Smooth the top of the concrete with a concrete spade and add any desired patterns or designs by hand or with concrete stamps. Let the concrete set overnight.
Remove the plywood and fill in the space with dirt.
