Thank you for writing.
You do not say what kind of hydrangeas you have and that can make a difference.
In general, the plant blooms on new, not old wood. Prune now and cut off dead blooms through the season.

Here is some good information from our colleagues in Anoka. https://www.anokamastergardeners.org/blog/2016/4/6/hydrangeas

This is a newspaper article for Minnesota. https://www.startribune.com/hydrangea-helper/62585782/

One final tip. You can, within the laws of physics, choose how pink or blue the plant is. It is not complicated. https://www.bhg.com/gardening/trees-shrubs-vines/shrubs/how-to-get-blue-hydrangeas/
Have fun.
