Hi,
As the title says really - have very tall 15ft-20ft high rhododendron which are flowering, but now blocking some light so need reducing in height.
The issue is conflicting advice on when and how much to prune. As they have just flowered, some advice is to prune now, other advice is after Christmas.
The question is which is the best time and how far can I reduce the height in one go plus do I just take the height off and/or shape the whole plant? Just for info we are in an area where hard frosts occur if that is important.
Thanks in advance if anyone can provide help.
