How to Kill and Keep Grass From Growing Outside Border

Question

We have grass in our backyard with a mower edge. On the other side of the edge is a rock garden. We have had a really hard time keeping the grass from going over the border and growing in the rocks. Last year we even dug down 6 inches on the back side of the border and sprinkled grass killer and covered it back up. We still have grass growing on the other side. I see other people’s yards and they don’t seem to have that problem. What are we doing to keep this up? And what is the best way to kill the grass that we have and clean it out of the rock? It is a mess. Any suggestions would be greatly appreciated.
