I have a mini-grove of old rhododenron (about eight of them, from 6 to 10 feet tall, close together) that were completely chomped (presumably by deer) when I moved in 4 years ago (in the Berkshires). Now that I have fenced the garden property, they have recovered nicely, with the bottoms filling in all the way up to the higher branches where the critters didn’t reach. I haven’t pruned except to remove dead wood and shape slightly. But I can’t figure out the flowering habit. They flower VERY late—late June or early July–and only seem to flower at the top, and then on alternate years! Can’t imagine why it is so inconsistant. This has been an off year. How should I prune them for better flower display? I don’t know the variety—flowers open very light pink and turn white. Any ideas?
