Without edging, your lawn grass will eventually grow over your sidewalks and driveways. This is caused by buildup of grass clippings and other organic material that settles along the edge of your paved surface. The grass then roots into this organic matter. Edgers allow you to quickly remove this organic material and grass to give your lawn that clean and pristine look. For best results, edge along paved surfaces twice per year--in the spring and fall.
Unroll a length of extension cord from your nearest outdoor outlet to the area you will be edging. Ensure the cord length reaches to the farthest area you need to edge. Plug the cord into the outlet.
Plug the edger into the cord and secure it to the edger with the edger's cord clip. Test the edger by squeezing the trigger to see if you have power.
Take a flat spade and push it into the grass along the edge you wish to start at. Lift it up to remove the grass that overhangs the paved surface.
Set the guide blade of the edger into place along the edge of the paved surface where you removed the section of grass.
Squeeze the trigger on the edger to engage the cutting blade. Slowly push it forward to cut into the grass. The blade should cut off all the grass that overhangs the paved surface, leaving a clean, defined edge between your lawn and your sidewalk or driveway.
Repeat steps 3 through 5 for each side of the driveway or sidewalk you need to edge. Dispose of edging cutoffs in your compost bin or local garden waste pile.
