Answer: I don't really know if the hole is evidence of disease or maybe physical injury from a garden tool or wildlife so I don't know how to guide you. If it is blooming, it must still be alive. I'd wait until it has finished blooming and then prune it back a little to promote healthy new growth. You may be surprised at how well it fills out. If it looks attractive, you may want to keep it. Hope so!
