I have an older Gardenia bush that is about 4' tall. This winter we had a few hard freezes, which is unusual for Benson, AZ. My Gardenia has dropped all its leaves and just has a few very small green branches on a few of the old branches. Do I need to cut the bush back to a few feet to help it recover, or what? I can't tell if the old branches are still green or alive.
