I searched the hydrangea forum, but couldn't find discussion as to whether or not I should deadhead spent hydrangea blooms. I have a Nikko Blue hydrangea which I think is a fairly common variety. Since I'm new to hydrangae, I'm wanting to deadhead spent blooms, to promote a late season bloom as well as make the bush more presentable.
I don't want to prune the bush, only to deadhead the blooms. Your advice is appreciated.
