I have an area I think is called the parking strip. I'm removing some ground cover. The soil is at the level of the adjacent sidewalk and curb, In order to put mulch in the cleared read (2-3 inches of mulch, just to have the area filed with something, not just dirt) I am removing dirt from that area, a great deal of work! Thinking that maybe a simpler method would be to remove the dirt around the edges so that the mulch doesn't spill over the sidewalk and curb? I'd love to avoid the work required to remove 2 or 3 inches of dirt. Input appreciated, thanks.
