A crisp steel edge keeps lawn out of your garden beds, holds mulch in place and gives the whole yard a professional finish. CoreEdge is designed so you can do it yourself: the lengths slot together and seven stakes per metre are built into each one, so there’s no trench to dig and no pegs to buy. Watch the 30-second video, then follow the steps below.
What you’ll need
- CoreEdge steel garden edging (each 1075mm length covers 1 metre once joined)
- A rubber mallet
- A length of timber, ideally about 110cm long
- Gloves and safety glasses
- A string line or spray paint (optional)
Step 1: Mark out your edge
Decide where your edging will go and lay the lengths out on the ground in the shape you want. For straight runs or smooth curves, a string line or spray paint makes the shape easier to follow.
Step 2: Link the lengths together
Join a few lengths at a time. The ends are pre-formed and slide together, and the edging can face either direction. If a join is a little tight, give it a light tap with the mallet.
Step 3: Press it into soft ground
If your soil is soft, push the edging in by hand and adjust its position as you go.
Step 4: Tap it to the required depth
On firmer ground, lay the timber along the top of the edging and tap it with the mallet, working along the run a little at a time until the edging reaches the depth you want. The timber protects the steel from the mallet. A piece about 110cm long is ideal because it presses down on two joins at once, which helps keep the lengths aligned and connected as they go in.
Tips for a clean finish
Work in short sections. Joining a few lengths at a time and tapping them in together keeps the joins from separating.
Prepare hard ground first. If your soil is very hard or rocky, water it the day before or loosen the line with a spade so the stakes go in more easily.
Check for hidden pipes. Look out for irrigation lines before you tap the edging in.

Open ends: finish exposed ends neatly with CoreEdge End Pieces.
Slopes: where the ground changes level, a Slope Adjuster keeps the edge continuous.
