My Jean Marie Montague has lost some of its' lower leaves. They turn, yellow/brown and fall off. Easy to just lift off without tugging at the leaf. I also noticed some of the inner branches have turned yellow. It is looking somewhat leggy. I have 4 rhodies all planted around the same time (about a year or so ago) The others are fine, except they aren't growing very fast. Is this normal? Should I be doing something? They are planted on the North-West side of my home. I have attached a couple of photos for you to review. As usual, "thank you"
