The easiest way to edge a flower bed is by using a simple half moon edger. This tool is used to cut the sod along any shaped flower bed. You simply work your way along any line you want and use the tool to cut the sod. By cutting the sod along a nice clean line you are cutting the roots.
As you can see in the photo, you want that cut edge of the sod to remain exposed. This prevents the grass from working its way into the flower bed. When you put your mulch in the flower bed make sure you taper the thickness down as you approach the sod edge. If you keep the roots exposed of the sod then they won’t invade the flower bed.
The half moon edger is very easy to use. When you’re creating a flower bed you can use a rope or garden hose to lay out a nice curved design. Then all you have to do is follow that curved design around and cut the sod with the edger. This is a really easy home improvement project that will spice up your flower beds. To maintain that nice edge just use your string trimmer, turn it 90 degrees and cut the edge nice and clean. You’ll have a great edge all summer long.
