I have (2) Rhododendron bushes on the side of my house, that were here when I purchased the home in 2013. I don't know how old the bushes are or when they were planted. I did, however, notice that
one day they were in spectacular bloom this Summer, and the next, the leaves had begun to turn brown and fall off, and the trunk of the bushes both were loaded with green/blue Fungus. I don't know if this is treatable, or whether I have to uproot both shrubs and replace them.
