How to Edge a Lawn

Print this article

Lawn edging provides definition between landscaped areas for both practical purposes and for visual impact. It helps keep mulch or soil in flower beds and grass growing solely where it is supposed to. Follow our guide to edge your lawn like a professional landscaper.

Step 1

Define Lawn Edge

Define Lawn Edge

Determine the exact placement of the lawn edge. Tidy the lawn edge by cutting a clean line around it using a spade or lawn edger.

Step 2

Dig Trench

From the edge defined in step 1, dig a trench to the depth of your wooden lawn edging. Remove the excess soil and put it into a wheelbarrow.

Step 3

Clean Trench Sides

Clean Trench Sides

Ensure the bank of the trench is cut vertically in preparation for the wooden lawn edging which will sit against it.

Step 4

Make a Tamping Board

Make a Tamping Board

Wear protective gloves to avoid splinters. On a wooden plank about 4ft long, mark the depth that you would like the edging to be buried. Some people like to have the edging protrude above the level of the lawn by a couple of inches, while others prefer to have the top of the edging level with the lawn. The latter choice will make mowing the grass easier as the wheel of the lawnmower can be run on top of the edging.

Step 5

Tamping the Soil

Use the marked plank to tamp the soil to ensure that the bottom of the trench is flat and at the right depth for your edging.

Step 6

Fit Weed Control Fabric & Edging

Fit Weed Control Fabric & Edging

Without using weed control fabric under the lawn edging, your flower bed would soon be overrun with grass and other weeds. Lay the fabric into the trench, parallel with any paths. Place the lawn edging firmly into the trench on top of the fabric.

Step 7

Trim Weed Control Fabric

Using a scissors, trim the weed control fabric behind the edging about 3 inches from the surface of the grass.

Make slits as necessary to allow your existing plants to protrude through the weed control fabric.

Step 9

Fill Trench

Fill Trench

Fill the trench with the soil removed earlier to push the edging firmly against your bank.

Step 10

Tap Edging into Place

Tap Edging into Place

Fine tune the depth of your lawn edging by using a lump hammer. Push extra soil underneath any low points.

Step 11

Walk on Soil
