Q.Hydrangea Type
I have hydrangeas but I don’t know what type they are. My husband has trimmed them back in the fall in the past, the following year they’ll get large but no flowers. This year I left them alone but it seems all the branches are dead (scratched them and no green). How do I get them to flower if I don’t know what type they are? These were here when we moved here.

Unfortunately, it looks like you have a H. macrophylla. In your zone, these will die back to the ground, and the flowers will only form on old growth. Unfortunately, if there isn't any old growth from the previous year, there won't be any flowers.
Mulching, heavily, in winter and removing in spring may help, some.
