I have a hydrangea, it flowered the first year we moved here, 4 years ago (it had been left for the previous 8 years, untouched) I pruned it back that fall and it didn't flower the following year. I thought I may have pruned it too much, so I left it, still no flowers. It is growing beautifully, but doesn't flower......any suggestions?
Thanks for any help
I am in zone 5b, southern Ontario. The plant is in sun/shade, beside a deck, in a garden facing south east

I have had luck keeping my mophead blooming by letting everything stand over winter, then in early spring I cut last year's blooming branches to the ground, then the rest to about 2-3 feet. That said, some years are heavier bloomers than others. Good luck.

Do you know if your hydrangea blooms on old wood or new wood? I would advise not to prune in the fall as you might be cutting off flower buds on old wood. If you really need to prune it, do it right after it blooms or wait until leaf break in spring and trim out dead wood. The last two winters have been hard on hydrangeas and even those that bloom on new wood have been killed above ground in certain regions but will usually resprout from the base of the shrub.
