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.

My advice would be to leave it for now to see if it recovers and move it- if needs be- later in the year-it could just be the conditions

But if it is a sickly plant then moving might haste its demise

I would remove the mossy bits though

Thank you so much for your advice. I will leave it and see what happens as the weather here is pretty horrendous at the moment. I'll definitely remove the moss and perhaps give it a feed. Time will tell!!!!

I wouldn't feed it just yet, maybe at the end of March?  But you could give it a mulch of well-rotted garden compost (keep it away from the stem) when you've got rid of the moss. 

We have a Rhododendron that looked like it was dying, but it later developed lots of health new growth lower down (where there were no harsh winds beating it up). Have cut the whole thing down to where the growth is healthy, and hopefully all will be well.

Thanks for the advice. I have cut back the diseased leaves and I can see new growth. I have also got rid of the moss and mulched it. Fingers crossed everyone that it will survive.
