The same principle applies to shrubs that are too tall. Take the branches down to the beginning and make clean cuts. No ripping. Rhododendrons are practically indestructible so you can be very aggressive. I brought one down to about one foot off the ground that was blocking a window and it bounced back and was lush and full. Believe! When? Immediately after they bloom is the optimal time but you can prune later as well just try to avoid very hot weather and water well after pruning. If it's righ

Some might think this is too much but it’s a very small area and sometimes you have to do what you have to do. Plus, it works out. I pruned mine way back in August and they are pushing out all kinds of growth now. It actually started to create new growth within 3 weeks of pruning. These things are pract
