A humble plank of wood in any size provides a terrific alternative to the string-and-spade method of edging a lawn. No more crawling around on your hands and knees, repeatedly adjusting a string. Lay the board flat, secure it with your foot, and drive a flat spade along one side. Move the board as you work your way down the bed.
Can You Dig It?
The classic tool for edging a bed is the half-moon edger, but any flat-bladed spade will do the job. Sharpening the blade with a metal file will make the job easier and give the cleanest cut.
