Hi, I live in Ma. My house is down below street level. There is a hill as most of my front yard that leads to a stone wall at the bottom. The front of my house is about 15 feet from the stone wall. It has grass but needless to say is difficult to cut. I wanted to replace the grass with something else but don't know what would work, I have 1 small tree out there but its just very blah & boring looking. I'm hoping it could be a DIY or something reasonably inexpensive to do.
