Answer: Frost hit alot of non-native plants hard this winter. If your gardenias are still alive, they should start sprouting new growth about now, as other frost-damaged plants are doing. Wait to trim back damaged foliage until you see the new growth, then cut back to it. Otherwise, it's easy to cut back more plant material than is necessary.Phoenix just had a good rain, so you probably don't have to water for awhile, but otherwise, water slowly and deeply so water soaks through the entire root zone to a depth of 2 feet. Don't fertilize until you actually see new growth. Good luck!
