How to Install Landscape Edging and Borders
Edging is the invisible backbone of a finished landscape. Without it, mulch migrates into the grass, turf creeps into flower beds, and the whole yard starts to look diffuse and neglected. The good news: installing it is straightforward work that transforms how a garden reads from the street. You're essentially laying down a physical barrier, staking it level, and backfilling. The result feels professional because it *is* professional—it's what separates a maintained property from one that's drifting.
- Mark the edge line with chalk or spray paint. Walk the perimeter of your bed or border and mark the exact line where edging will sit. Use landscape chalk or temporary spray paint. Step back and look at the line—it should follow the contour of the bed, straighten any wobbles, and account for sight lines from the house and street. Straight lines look intentional; wavy lines should flow naturally, not hesitate.
- Clear and level the trench area. Cut along your marked line with a spade, creating a shallow trench about 2–3 inches deep and 4–6 inches wide. Remove any grass, roots, and debris from the trench bottom. Use a level or your eye to ensure the trench sits at consistent depth along the entire run. Compact the soil at the base with your foot or a hand tamper so the edging won't settle unevenly.
- Lay out and position the edging material. Unroll or place your edging material into the trench. For plastic or metal strip edging, snap it into position end-to-end, allowing slight overlap. For stone or brick borders, arrange pieces dry first to confirm they fit the line without gaps. Leave edging slightly proud of the soil surface—about ½ to 1 inch above grade—so it functions as a true barrier between lawn and bed.
- Secure edging with stakes or fasteners. For flexible plastic or metal edging, drive stakes (included or purchased separately) through the pre-drilled holes every 2–3 feet. Hammer stakes at a slight angle away from the bed to lock the edging firmly in place. For stone or brick, apply construction adhesive to the base or use a sand bed to set it; no stakes needed. Check that nothing rocks or moves when you press on it.
- Backfill and compact soil behind the edging. Pack soil firmly against the inside face of the edging to lock it in place and eliminate gaps where water can seep or grass can creep. Use a hand tamper, your heel, or a small sledge to compact in layers. The soil should be flush with the top edge of the edging material, creating a clean transition between bed and border.
- Edge the lawn side with a shovel cut. Stand on the lawn side of the edging and make a clean vertical cut with a sharp spade along the outer edge of the edging material. This removes any grass roots that would otherwise creep into the bed and creates a crisp lawn line. Sweep away clippings and debris from the trench.
- Backfill the bed with mulch and water. Add mulch, topsoil, or planting material to the bed, filling to the desired level. Rake smooth and mound slightly away from the edging. Water the area lightly to settle the new material and firm the edging in its final position. The edging should now contain the bed cleanly and prevent turf encroachment.
