My rhododendron bush, however, is not doing well. I have no luck with them. Over the years I have planted three bushes. They look fine for a few seasons, and then start to go into decline. I plant them in a sheltered, moist, semi-shady location, and feed them acidic fertilizer, but they never thrive. It's odd, because I have no problems with azaleas which belong to the same family. This year the rhododendron is mostly bare branches with some sickly looking leaves, and a half dozen clusters of flowers.
I've decided that after it blooms, I will put it out of its misery and dig it up. I will plant an azalea in its place.
