Welcome , mtemm!
Congrats on your new home!

I've often thought that it would be a wonderful gesture to leave a "garden plan" for new home owners, detailing what's planted where, the age of the plants, etc. Not that I'd ever get around to doing it for someone if I was moving, but it would be helpful!
I just planted my first 2 hydrangeas last year, so they're an experiment to me. I do have a climbing hydrangea, that I've had for several years, though.
The following link is my favourite for hydrangeas, and the pics are gorgeous, and helpful, if you've trying to figure out what kind yours are. There is a section on pruning in the Hints & Tips, and another link with diagrams on making the cuts.
Hydrangea hints & tips!
I hope that everyone's suggestions and links, help you out. Keep us posted, okay!
