Landscaping Edging with Structural Recycled Plastic Lumber

Landscaping edging fulfills both functional and aesthetic purposes. It cleanly separates the boundaries between your lawn and your flowers and shrubs, providing a neat border. This means that grass won’t start encroaching into your garden, and the loose soil or mulch won’t spill onto the lawn. Learn these easy steps to installing plastic landscaping edging for your home.

Outline the Area

To start, determine the area that you want to enclose with the landscaping edging. You should measure around it to figure out how long your edging will need to be and how much you will have to buy. For thin plastic edging, measure by placing a rope where the edging will eventually go, marking the point where the rope goes fully around the area, then straightening the rope. Use measuring tape to determine the length up to that marked point.

If you are using edging that does not bend, you should make an outline without rounded edges. In this situation, you can measure directly without a rope.

Dig a Trench

With the outline done, dig a trench about three to six inches deep around the perimeter of your chosen area. How wide you make the trench will depend on how thick the edging you select is, so you should measure it and dig accordingly. You can use a shovel or digging tool to complete this step. Keep the dug-up earth near the trench for later.

Put in the Edging

Now that you have the trench, place the edging into it. If there’s some wiggle room, you push the edging against the trench side closest to that surrounded area as well. The top of the edging should be a couple of inches above the level of the adjacent ground.


Fill the trench in with the soil that you dug up earlier and smooth out the surface. Pack the soil tightly to maximize stability. You can also step on it or water it with a hose to pack it in better. With that done, your edging should be complete!

If you want to install edging in your yard, consider using recycled plastic landscape timbers. They are sturdy and impervious to moisture, insects, and rot. Additionally, because they are made of recycled HDPE plastic, they are eco-friendly. Contact Bedford Technology to learn more about plastic lumber and how to use it for landscaping.
