I wonder if anybody has success with growing Nova Zembla rhododendrons. I bought 2 of these beautiful rhododendrons 6 years ago in New York, and they almost never grew or bloomed properly, even after I transplanted them to a new place (in Connecticut). They both just looked miserable, with very few leaves on top, and almost no flowers. There were no signs of pests or diseases. This year I bought another one in the spring which looked gorgeous and was blooming profusely. It was growing nicely and looking good all summer, but in September I noticed that the leaves turned pale and dull, drooped and curled a little bit. Again, no signs of pests or diseases (and I spray it with Neem oil from time to time). The soil has good drainage, never soggy (just moist), and I checked the roots today - they are not diseased or rotten. Some of the leaves browned a little bit, and dropped, but the rest are OK, just dull and pale color, and curled, - like on my old 2 rhododendrons. I once saw Nova Zembla rhododendrons in one garden center for sale which were the same color and a little curled. Maybe it is common for this variety to have this kind of leaves? But why are the old 2 rhododendrons losing their leaves (almost bold!) and not blooming? They are in partial shade. The new one gets about 6 hours of sun in the summer. I fertilize them once a year in the spring with Holly Tone.
