How to Build a Garden Bed with Landscape Timber Edging
If you have decided to construct a garden bed, timber edging will enhance the beauty of your garden area and make it more beautiful. Apart from this, you can build the garden bed with landscape timber as well.
Landscape timber seems to have an advantage over other materials because it needs less work than concrete, brick and stone. You need 8 pieces (6 by 6 each) of landscape timber for this project. But half of them should be 4 feet long and the rest 8 feet long.
Step 1 – Cutting the Timber
Saw about 5½ inches from every timber piece because the actual length is 5½ inches and not 6 inches. Lay the timbers on the area where you want to build the garden bed and use a shovel to mark your garden bed’s borders.
Step 2 – Laying the Timber
Place the first 4 pieces of timber and check that each edge meets the edge of the next timber clockwise. Drill pilot holes with a ½ inch bit every 2 feet and check the pieces of landscape timber with a level. Fix a rebar piece into one of the holes that you drilled and use a hammer until the rebar is flush to the top of the timber piece. Fill the other holes with rebar pieces as well. They will go down as deep as 12 inches to provide an excellent foundation for your garden bed.
Place the next layer of timbers counterclockwise on the base of the garden bed, letting the corners of the timbers overlap in an opposite direction compared to the previous layer of timbers. Use 2 timber screws to attach the layers together in the corners. Fix 2 other screws on each edge but they should be evenly spaced between one and the other. Fill the garden bed with topsoil and compost.
Step 3 – Installing the Edging
Use stakes and a hammer to mark the corners of the garden bed. Attach a piece of string among the stakes to mark the bed’s measurements. Use a shovel to dig the edges under the string at a depth of 6 inches. Make sure that the trench has an extra width of 2 inches so that the timbers will not elevate when the soil freezes in cold weather.
Drain the trench from soil and check that it is level. Put the first timber row on the widest edge of the garden bed and stack the rows on top of each other. Move the timbers a bit to avoid lining-up of the edges.
Buy rebar pieces which are one-third the height of your timber edging. Equip a drill with a spade bit and an extension bit and drill down through the center of the top edging and along both meeting points of the edging. Put the rebar into the holes and make sure that the rebar is flush with the top of the timber edging.
