Rhododendron Issue

Question

Part of my rhododendron plant which we planted this spring looks wilted and unhealthy. The other branches seem ok. I am not sure if sun or water is to blame. The plant gets full sun but the healthier side gets less sun. Thanks for any help!

Go ahead and trim away and discard any leaves and stems that look bad, remove all the old remains of flower heads and give it a couple treatments with neem oil. Then, later in the year, you may want to give it a severe pruning and a new start. Here's an article that will help:
