When shaping a Hydrangea as you want it to be, do it
over a couple of years, successively, taking out a stem here and there
each year so you still get flowers. Trim it all back and you'll get
no flowers at all.


Mine flowers whatever you do to it, including pruning back to ground level
(yes, I have tried!).

(But it's a very well-established one, and a tough as nails mophead - I'm
sure you are right that the pruning of the young plants is causing Colin's
problems)
