When should I cut back my Hydrangeas? This is the first year I have had

If you don't get a better answer, I'd do it in late winter when the
frosts are over when you see the new green buds starting to swell. Cut
back to a pair of healthy-looking buds, just which ones depends on how
high you want the shrub.

Well, that's what I do. Haven't sent them extinct yet!
