best time to repot hydrangea that is getting too big for its pot
I have a potted hydrangea that grew considerably since last Summer. There are now six mopheads, 3 of which are in full bloom. The overall plant looks like it is too big for the planter, and I think I should pot it up sometime before next Spring. But when is the best time to do so? Should I wait until next Spring, and just after danger of frost has passed?
