What is Killing Native Rosebay Rhododendrons?
About five years ago I noticed a spot on my property where a group of several large rhododendrons had died, and ever since I'm noticing that more and more rhododendrons are dying. They used to be so beautiful on the banks of the creek but now they are mostly dead. I live near the Blue Ridge Parkway and I see so many dead ones by the Parkway that it is becoming an eyesore. I've asked a few people and nobody seems to know what's killing them. Does anyone here know what is killing the native rosebay rhododendrons in SW Virginia?
