Landscape edging for gravel keeps loose stone where it belongs, stops it from washing into your lawn, and gives your beds a crisp, finished line. With the right edging type, a few basic measurements and proper anchoring, you can set a border that holds for years. This guide walks through choosing the edge, preparing the trench and installing it so it stays level and tight.

Choose the Right Edging Type for Gravel

Gravel shifts more than mulch, so the edging has to resist both outward pressure and erosion. Rigid materials work best. Steel and aluminum strips, poured concrete and heavy plastic profiles all hold a line well. Stacked stone or thick timber also works if you anchor it properly. Thin flexible plastic tends to bow under gravel weight, so avoid it for borders deeper than a few inches.

Match the edging height to the gravel depth. A common rule is to keep the top of the edging about 1 inch above the finished gravel surface. That lip stops stones from spilling onto the grass without creating a tripping hazard.

Prepare the Trench and Base

Mark the border with a garden hose or spray paint first, then step back and check the curve from several angles. Once you are satisfied, cut a trench along the line.

  1. Dig the trench about 2 inches deeper than the edging is tall, so the top sits at the right height once it is set.
  2. Make the trench about 3 to 4 inches wide for strip edging, or wider for stone or timber.
  3. Spread 1 to 2 inches of compacted crushed stone or road base in the bottom. This gives drainage and a firm footing.
  4. Tamp the base flat with a hand tamper and check it with a level along the full run.

Install and Anchor the Edging

Set the edging into the trench, keeping the top edge at a consistent height. Check it with a level every few feet, especially on curves. Drive stakes through or alongside the edging at 12 to 18 inch intervals. Stakes should sit flush or slightly below the top rail so they do not catch a mower or trimmer.

Backfill the outside of the trench with soil or sand and tamp it in layers. Firm backfill is what keeps the edging from leaning inward when the gravel is pushed against it.

Add the Gravel and Finish the Border

Spread landscape fabric inside the bed if you want to slow weeds, then fill with gravel to about 1 inch below the top of the edging. Leaving that gap prevents stones from rolling over the lip during heavy rain or foot traffic. Rake the surface level and check the border one final time.

Common Mistakes to Avoid

  • Skipping the base layer, which lets the edging sink and tilt over the first season.
  • Setting the top above gravel level, which makes stones spill and wear the lip.
  • Using too few stakes on curves, where the pressure of the gravel is highest.
  • Filling the gravel right to the top edge, leaving no room for settling.
  • Choosing thin plastic for deep beds, which tends to bow outward.

FAQ

How deep should landscape edging be set for gravel?

Set most edging about 2 to 4 inches into the ground, depending on its height. The top should sit about 1 inch above the finished gravel surface.

Can I use plastic edging with gravel?

Only heavier, rigid plastic profiles work well. Thin flexible plastic tends to bow outward once gravel presses against it, so use it only for shallow borders.

How often do stakes need to be placed?

Space stakes every 12 to 18 inches, closer on curves where the gravel pushes hardest.

Conclusion

Landscape edging for gravel works best when the trench, base and anchoring are all done properly. Choose a rigid material, set the top about 1 inch above the gravel, and check it with a level as you go. A well-installed border will hold its line and keep stones in place for years.
