I've had branches snap off leaving only a small amount of "bark" on it and they've still grown. On big breaks in late flowering I usually make a collar out of a piece of 20mm ag pipe about 30mm long cut along the side. I just strap it on using tie wire. I feel that wire or string used directly on the branch cuts off the circulation to the area and slows down healing. I've also forgotten about wired branches and lost the wire from the branch growing around it. It's too bad you don't have any pics, she sounds phat.
