Since I live in Zone 5, I have to really insulate these guys for the winter. They are only hardy to Zone 6. After the trees dropped their leaves, I used twine to tie the branches together in a conical shape. I then used metal stakes to surround the trees then wrapped chicken wire around the stakes, making a frame. I filled the frame with leaves, pine needles and other garden debris; then finally wrapping burlap (old coffee bags from my local coffee shop) around the chicken wire. I also did this to a new rose bush. Hopefully all will be well for the trees and they will produce a lovely crop of figs next summer.
