No bloom hydrangea

Question

I have a mophead hydrangea that is at least 10 years old. It’s very large,has healthy leaves, but hasn’t bloomed in 3 years. Before this it was full of flowers, then it started to get flowers on one side, now nothing. Is there anything I can do this fall to help encourage some blooms–I really miss them. Thank you
