Is there way to protect the wire from being cut by a string trimmer or an edger?
The wire can be covered at areas you suspect you may cut it by using a few pegs closely, touching one another. The pegs heads will create a relatively good protection for a string trimmer. If you use a metal blade edger, it is recommended to bury the wire at 3 inches deep and protect is with pegs. It is also recommended to mark the sidewalk edge with paint, so you know to be careful and raise the edger blade or avoid this area altogether.
