How to Use a Landscape Edger | Clean Lawn Borders In 5 Steps

For the full breakdown, see our best Edging Tool guide.

The line between turf and hardscape can vanish fast without regular edging. A clean border transforms an ordinary lawn into something intentional, and doing it right takes less time than fixing the damage from rushing. The process works for most gas or electric edgers on standard US lawns: prepare the ground, set your stance, guide the blade, then clean up. Here is the order that delivers consistent results without gouging the turf or fighting the machine.

Prepping the Lawn for Edging

Mow the lawn to your normal cutting height first. A shorter, uniform grass height makes the turf line visible and prevents the edger from throwing long clippings sideways. Walk the edge line and pull out any rocks, sticks, or large debris — loose objects create kickback or chip the blade when the edger hits them. If the soil is dry and hard, a light watering an hour before helps the blade cut through rather than bounce off the surface.

Before you pull the starter cord, look at your edge. For straight sections along a driveway or sidewalk, ride the edger’s guide wheel on the hard surface and let the concrete or asphalt steer the cut. For curved beds, irregular corners, or new border lines, mark the path first. Stakes and string work well for long sweeps; a garden hose laid on the ground handles tighter curves. Echo’s guidance emphasizes keeping the guide wheel on pavement, never on the grass, to avoid uneven cutting and loss of control.

Grip, Stance, and Blade Setup

Stand with your feet shoulder-width apart, knees slightly bent, and hold the edger close to your body. A tool held at arm’s length pulls you off-balance and makes small guiding adjustments impossible. Set the cutting depth between half an inch and two inches — shallow enough to trench the edge without scalping the turf. For routine maintenance, aim for about half an inch. Overgrown edges where grass has crept over the sidewalk may need a deeper second pass after the first shallow cut.

The guide wheel rides on the hard surface, not on the grass. Position the blade so it barely touches or sits just above the soil line. When the wheel follows the pavement and the blade skims the dirt, the depth stays consistent across the whole run. Turn off the engine before any blade adjustment, per Lowe’s safety guidance.

Making the Cut: Straight Lines and Curves

Start at one end of a straight section and walk at a slow, steady pace. The blade does the work — pushing or forcing the edger through compacted soil or roots pulls the machine off line and leaves a ragged trench. Let the edger feed itself forward; if it slows down or the soil feels hard, repeat the pass at the same depth rather than muscling through.

For curves, corners, and areas near flower beds or stone pavers, slow down more. Trying to turn a power edger in one smooth arc usually digs too deep on the inside of the curve or misses the outside entirely. Home Depot’s guidance recommends multiple shallow passes on curved sections, cutting a little further into the line each time until the edge matches the guide. A string line or garden hose gives you a visual target to follow on each pass.

After the Edge: Cleanup and Touch-Ups

Rake or blow the loose soil and clippings off the hardscape before they dry and stain the surface. Inspect the edge for gaps, divots, or spots where the blade skipped. On thin or bare patches where edging exposed soil, reseed lightly and water in. The final edge should be clean enough that the lawn and hard surface meet without a muddy transition — that cut line is what makes the whole yard look finished.
