I've made wreaths with hydrangeas, and found it's easier to attach them to the base when they're fresh, and let them dry on the wreath.

Thanks sylky00, I found that out too...
I was wondering if theres something you could spray on them so they won't fall apart so much??
I've tried hair spray, clear paint, and these just make them more brittle, I was wanting something to make them stay pliable so they won't shed so much... linda

I really don't think such a product exists. The only alternative is glycerin-preserving, but then they have to be artificially colored, which I try to avoid. Maybe a cooler room temp. would help.
