Can I save my rhododendron?
I have had 2 identical rhododendrons side-by-side for over 7 years. They are in full sun and have large pink blooms. The one on the left has been ailing for the past year. It is shriveling up and dying. I cut off the afflicted branches, but they look sick inside and the problem is spreading. Can I do anything to save it? Is the healthier one at risk?

It is impossible to tell for sure from your photos but your rhododendron could have multiple problems, including borers or a disease.
We'd suggest pruning back the wilted branches into healthy wood.
