How to Edge a Lawn

Neat edges transform the look of a lawn. Even a slightly scruffy lawn looks better with crisp, defined borders. Here is how to create and maintain them.

Tools for edging

• Half-moon edger: For cutting new edges or re-cutting overgrown ones. Creates a clean, vertical cut.
• Long-handled edging shears: For trimming grass that hangs over the edge. Use after mowing.
• Strimmer/line trimmer: Quick for long edges but less precise than shears.
• Powered lawn edger: For large lawns or frequent edging.

Creating a new edge

1. Mark out the line with string or a hosepipe for curves.
2. Stand on the lawn side and push the half-moon edger vertically into the turf.
3. Cut to a depth of about 8-10cm.
4. Work along the line, overlapping cuts slightly.
5. Remove the strip of turf from the border side.
6. Clear away loose soil and debris.

For straight edges, use a plank as a guide. For curves, work freehand or use a hosepipe as a template.

Maintaining edges

Once you have a good edge, regular maintenance keeps it looking sharp:

• Trim overhanging grass with edging shears after each mow.
• Re-cut edges once or twice a year with a half-moon edger.
• Keep borders slightly lower than the lawn so grass does not creep over.

Permanent edging

If you want to reduce maintenance, install permanent edging:

• Metal edging: Thin steel strips that are almost invisible. Long-lasting and effective.
• Plastic edging: Cheaper but can look less natural and may become brittle.
• Brick or stone: Attractive and durable. Set flush with the lawn for easy mowing.
• Timber: Gives a natural look but will rot eventually.

Repairing damaged edges

If an edge has crumbled or been damaged:

1. Cut out a square of turf including the damaged edge.
2. Turn it around so the damaged part is inside the lawn.
3. Re-cut the edge.
4. Fill the gap where the damage now is with soil and seed.

Tips for better edges

• Edge after mowing, not before.
• Keep tools sharp – blunt edgers tear rather than cut.
• Collect the trimmings to prevent them rooting in borders.
• Do not cut too deep or you will weaken the lawn edge.
