I too have the same problem, but it's almost July in NJ and I have new growth but lots of dead twigs like you. How long do you wait before pruning the old dead ones. Last year,I waited all summer. Thus year I think I pruned too early. I wish they would answer about original(northern nj reblooming )hydrangias mopheads
