I can vouch for dense rock deterring gophers. My native soil is dense rock and clay. I don't think there is a gopher in his right mind who would try to tunnel into that stuff. Why did I even think I could garden in it ???
Mrs. J had soil imported for the front yard and that's where I have had my gopher problems this year. They used to be happy living in my neighbor's yard until he stopped all gardening activity including watering. Then they moved to my front yard ... especially to Mrs. J's roses.
Smiles,
Lyn
