How to Pick the Correct Edging for Your Rocks
The simplest and most subtle landscape edging borders that effectively separate your lawn from a garden are 4-in.deep strips of steel, aluminum or plastic.
The metal lawn bends easily into smooth, graceful curves and stops the spread of grassroots. However, painted aluminum and steel offer sleek and refined garden edging. This is because they almost disappear against the grass and garden bed. The plastic types of garden edging have a prominent black bulge along the top edge.
All work best on fairly even terrain. If you have a lot of dips and rises, it’s easier to install a paver border.
Additionally, if there are pests you need to keep out, you may want to consider flower bed fencing.


Although both aluminum and steel landscape edging cost about the same, we chose aluminum because it was much lighter. It weighs about 41 lbs. per 100 feet, while steel weighs about 225 lbs. With aluminum landscape edging, you’ll get a professional look without the heavy lifting.
Plan to set the garden border with the top edge about 1/2 inch above the soil level to maintain the lawn/garden separation. Even more so, this will keep roots from crossing over the top. This makes the garden border almost invisible and allows you to mow right over the top. However, be aware that the top of the thin lawn edging can hurt bare feet. After cutting it, make sure you round off any sharp edges with a file.

How to Install Landscape Edging
1. The key to setting this garden border is to cut a clean vertical edge along the grass with a square spade.
2. Then you can lay the garden border tightly against the edge when you stake and backfill it.
3. There’s no rule for shaping the edge. Simply follow the edges of your lawn, making smooth, gradual curves. To make smooth, sharp curves, bend the metal lawn edging around a circular form.
