I have a rhododendron that is looking VERY sickly this year. Early in the year we had to cut off part that had died and it hasn't got to looking any better. I want to try and save it but I if it has something I don't want it to spread to the other plants. I think it bloomed but barely this year. These have been here since we moved in about 5 years ago and this is the first year any of them have acted sickly. I hope the pics may be able to help. Please help me save it!!
