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.

This is a newspaper article for Minnesota.

One final tip. You can, within the laws of physics, choose how pink or blue the plant is. It is not complicated.
Have fun.
