Edging is an essential part of lawn care, as it helps to define the borders of your lawn and create a clean, finished look. While you can purchase a dedicated edger, you can also use a string trimmer to edge your lawn.
There are a few benefits to using a string trimmer as an edger. First, it is more versatile than a dedicated edger, as it can also be used to trim grass and weeds. Second, it is often less expensive than a dedicated edger. Finally, it is easier to use than a dedicated edger, as it does not require any special skills or training.
