Rhododendron possibly dying
I have a small, not very well established rhododendron that I uncovered in a border last summer just after I moved into the property. It has been doing absolutely fine until recently when we've had hard frosts, snow, heavy rain and gale force winds!!! The leaves are sagging downwards and I've noticed that they are starting to turn brown all over as if they have died. At the base of the plant there is a lot of moss growing around it. There is another rhododendron in the same border which is perfectly healthy. I wondered whether moving it may help?? I would very much appreciate some advice on what I can do to help this plant as they are so beautiful when in flower.
