Goeffrey,
Don't try that technique for winter protection. My mother used to raise
200 Hybrid Tea roses and every year she and Dad used to bury them using a
technique that came to be called the "Minnesota tip." When she heard about
the chicken-wire with leaves in it, she tried it and lost every one of her
prized plants. By the way, those styrofoam plant covers are equally
worthless for winter protection.
