Hello, we moved to Kansas from the southwest about a year ago and though I have many questions this is the one I have for today. I have a failing dry-stack limestone retaining wall next to my patio. The wall is holding back a sloped garden area, and some of the stones have shifted, collapsed, and washed out. How do I maintenance this area? This is all new to us and I want to learn more so I can do what I can myself.
