How should I prune this Stewartstonian Azalea
I've had this plant for about 3 years. It has survived but barely, so about a month ago I moved it to a spot where I thought i might be happier. I planned to prune it after flowering but it just occurred to me that it may not sprout new foliage on those bare branches. As you can see (although I realize it's kind of hard on this photo), it's very sparse. I'd like to prune a bit for shape (it's lopsided at the top) but mostly for health. Any recommendations?
