I have a 15 year old ceanothus (very small leaf variety), which is about 12-15ft high, has a spread of about 12ft in diameter & is covered in blue blossom every spring. It has, however, a lot of dead wood underneath the canopy. I would like to prune it or, preferably, cut it back hard to say 7 or 8ft high. Can this be done, so that it continues to flower? And what is the best time of year to do it please?
