How old is he?
I think the biggest response you are going to get is make sure hes tied to you when you go outside with him, don't leave him alone to eat the rocks.
Followed up by exercise, exercise, exercise.
My boy used to eat mulch and threw it up. I quickly fixed that by staying with him like a general. Now he just likes digging. Even if I'm standing next to him. He runs to a new spot and digs. Even on a leash. He thinks its so fun. His tail goes crazy. A dig drive!
