Suggestions for retaining slight slope in yard by sidewalk
My front yard is mostly level but slopes slightly towards the front of the house, and then drops off by 1-2 feet rather quickly by the sidewalk.
There's a garden along this drop-off and I need to do something to prevent erosion of dirt onto the sidewalk. There used to be an ugly chain-link fence with cinderblocks at the base holding the dirt in place, but I removed it.
I was considering building a short retaining wall but the issue is there's a maple on the street on the other side of the sidewalk, and to properly dig the retaining wall, I will have to dig too close to that maple, and I'm not willing to do that.
Any suggestions on what I could do to beautify and retain the dirt would be really helpful!
