Expert Response
Annabelle Hydrangeas bloom on new wood. That is the new growth that you see this year. You can prune them back in late winter all the way to the ground if you like.
This time of year you can prune out any dead stems and back to a shape or height that you like. You should do this before the new growth begins as you will have less chance to accidentally prune the new growth.
It will bloom on the new growth that comes this year.
