Want to liven up your garden with attractive and hardy landscape timber edging, but not sure where to begin? We’re here to help. Landscape timber is a great choice for a garden—its natural look is more attractive than steel, and it’s much more durable than plastic. Even better, it’s relatively simple to install. We’ll walk you through creating edging on a flat surface or on a slope: read on for our comprehensive guide on how to install landscape timbers.

    Set up mason lines to mark the locations of your landscape timbers. For a simple garden edge with a rectangular design, set up stakes at all 4 corners of your garden, and pull a mason line taut between each stake. If your planned garden is large enough that it’s difficult to keep a single line taut between two stakes, add an additional stake midway along your garden’s length or width. [1]
    • If you don’t have a mason line, any other kind of string can work just as well.
    • For ease of access, try not to have your timbers set at a width of more than 4 feet (1.2) meters from each other if you’re planning on creating a garden. [2]
    • Although the length of the rectangle can be as long as you’d like, if the rectangle is too long, it’ll be difficult to reach your plants without stepping in your garden. [3]

Create trenches for your timbers.

    For tough turf, use a sharp spade . [4] These trenches will need to be wide enough to accommodate the size of your timber—usually 4 to 6 inches (10 to 15 cm) across. Remove as much organic matter, like roots or other plant residue, as you can. [5]
    • If you’re working on a shallow slope (under 10 degrees), dig approximately 8 inches (20 cm) into the ground from the higher end of the slope. For steeper slopes, dig 12 inches (30.5 cm) into the ground. [6]

Even out the bottom of the trenches.

    Run a level along the bottom of your trenches, removing or adding dirt as needed to create a level surface. With your hands or the back of your spade, tamp down the soil at the bottom of the trenches. [7]
    • To add longevity to your timbers, add a layer of sand or gravel about an inch (2.5 cm) thick to the bottom of your trenches. [8]

Add landscape fabric (optional).

    Install landscape fabric if you want to keep out weeds. To do this, roll landscape fabric over the trenches, then drive it into the ground with small stakes and a hammer. Trim any extra fabric that hangs out over the edges. [9]
    • This step is optional—if you aren’t worried about weeds in or around your trenches, it’s okay to skip this step.

Cut your timber to fit the trenches.

    Measure the length of each trench, and use this information to decide how many pieces of timber you’ll need. If you need a shorter piece of timber at the ends of each trench in order to match its length, mark the length of timber you need on a longer piece, then cut it . A circular saw works great for this, but a hand saw can also do the trick. [10]

    Use a level after placing each log so that you can be sure they’re level against the ground. If a piece isn’t flat against the ground of the trench, add or remove some soil from underneath it. [11]
    • To make sure your timber edging lasts for a long time, use rot-resistant wood. Cypress, cedar, redwood, or pressure-treated wood can last beyond 7 years, while less durable options might need to be replaced earlier. [12]

Build your second layer of timber (optional).

    Be sure that the layers of timber line up smoothly. If you’re having trouble making sure the second layer is level, place wood shims between the levels. [13]
    • This step is only necessary if you want a taller garden edging. If you’re satisfied with the height of a single layer of timber, there’s no need to install a second.

    Pre-drill your wood with a power drill. Use a drill bit that is slightly smaller than the size of the rebar stakes that you’ll eventually be placing into it. By doing so, you can prevent your wood from becoming damaged. [14]
    • If you have 2 or more layers of timber, drill through all of them at the same locations.

Secure the timber to the ground.

    Place the end of a rebar stake into the hole that you pre-drilled. Then, drive it through the wood and into the ground with a hammer. Use a hammer to push the rebar stakes through the timber, ideally using rods or rebar stakes long enough to be driven 2 feet (0.6 meters) into the ground. [15]

    For any areas near the timber that aren’t level with the ground around it, add dirt or soil. Tamp down any gaps that you’ve filled with soil. This will keep your timber even more secure and create an attractive garden edge. [16]

      Warnings

      • Even pressure-treated wood has a much shorter lifespan than other materials because of its contact with soil. If you want a more permanent solution, consider using stone or metal. Pressure-treated wood in contact with wet soil can last 5 to 15+ years (or less) depending on the site conditions and wood quality.
