I haven't pruned my hydrangea since last fall since I cut it right back to rejuvenate a bit. Just this past May or June it developed only 3 or 4 very huge blooms, (which I expected). Those few blooms are beginning to fade now. Well, just today, I noticed about a couple of dozen new blooms at the tops of the stems developing. Is this normal for September? I don't know what kind of hydrangea it is but it's blue. Thanks everyone for your help.
