Suggestions for roadside slope
I have a stone wall in my front yard which borders the road. There is about a 3' drop to the road. Of course it is sand, rocks, salt, etc. I've tried Yarrow, catmint, sedum, but nothing takes. I wasted 2 yards of mulch a couple of years ago, and I'm hesitant to add fresh soil due to the steep slope and the snow plows. Any sugestions?
