Plastic lawn edging can be a useful tool in preventing grass from creeping into garden beds. It also keeps stone and gravel mulch from landing on your lawn and becoming a hazard in your lawn mower. Edging often lends a neat, tidy and crisp look to both lawns and garden beds. Use plastic edging to create curved lines that are pleasing to the eye, creating interest and a pleasing, natural design flow in your garden.
Use a spade to puncture a line into the soil to use as a guide for excavation and for installing the edging. Do not dig a trench; just cut in a line that can be used as a guide for setting the edging in place.
Remove grass, stones, plant material, roots and other objects that cross over your installation line. Rip up runners from grass or other plants near or heading toward the line.
Lay your first piece of edging into the soil in the cut line, and use a mallet to drive the edging into the soil until the top of the plastic edging is just above grade. Repeat this process with successive pieces of edging.
Place support spikes on alternating sides of the edging at the recommended intervals. Use your mallet to knock the spikes down into the soil and secure the edging.
Cut edging where needed to fit, using a hacksaw or sharp utility scissors. Overlap cut ends slightly for the most professional look. Secure the seam with a spike, if necessary.
