Our house sits on a hill and the side of it is a slope. almost 45
degrees. The people who lived here before us had some mulch there and
a crappy rock wall made of just stones they found in the yard. We're
cleaning it up but the problem is, what to replace it with? We planted
some hedges and what not along the side and I built a retaining wall
at the bottom. But if we use either mulch or stone, there has to be
something dividing it from the grass. I've checked Home Depot and
places like that but all they have are edgers and those kinds of
things. Because of the grade, the angle would look funny with a
squared off rock. Any suggestions?
