My large Rhododendron is looking very sad and was last year, though it flowered a lot. This year, the leaves look as though they are very sad. Can you tell my why? We live in East Anglia, have acidic soil and a profusion of Rhody's. The smaller plants seem to be fine but the larger one over 6 ft looks very sad. They are all in the same location in the garden. It is a large Bright Red. We have only been here 1 year and it looked a bit sad then (March) like a dog with its ears down. It's been fed with Iron and a specific Rhody feed.
