Pacific Northwest Gardening: Rescue Rhody is blooming!, 1 by KatyMac

My bi-polar occasional "handy man" brought me this poor rhododendron he rescued from a wooded area being cleared for building. It was so bedraggled I was very dubious. But as he was in his manic state he had his shovel out and was digging a hole before I could think of a tactful way to say "thanks but no thanks". I've sprayed it with MightyPlant every couple of weeks since I got the MP and I guess it's decided to live after all. It's not the most attractive plant in the yard and I'm wondering if I could/should prune it now or would that just stress it more?
