Fruit trees and gophers
Living here in gopher country, otherwise known as California, I have long been planting roses and shrubs in undergound wire cages to keep the roots safe from destruction, and my tomatoes in a raised bed with a wire barrier "floor" for the same purpose. Now I am in the planning stage of expanding my fruit trees. I am considering using the tree sized gopher cages for planting them, but I'm concerned about the tree roots growing through the holes and eventually being strangled by the wire. Is this an issue? or do the wires eventually rust underground before the roots get big enough for this to be a problem?
