I have about 12 rhododedrons around garden, some in pots, some in ground. About 4/5 of them haven't flowered for past 2/3 years even though the keep producing loads of new shoots and getting bigger and bigger, why is this? They may produce say 1 flower but thats all - should I be pruning them? I do deadhead them once they have flowered.
Thanks for the responses. Some of the rhodys are in pots, some in the ground and I'm not feeding any of them which I suppose is a mistake. I've never pruned them either which I was wondering if I should do but when? My husband says that nobody looks after them in the wild and they all seem to flower great!!
