If this is a mophead hydrangea, then pruning can be tricky, because it will flower on last year's growth. I try to resist pruning at all (having made many mistakes with them in the past!) except to remove all of the withered flower heads after all chance of frost is over. Then you can see which stems are putting on growth and if necessary cut out old dead wood.
