Should I remove spent flowers of 1st year ES hydrangea/
I planted a few ES this spring and they have been doing great. A few pink/blue flowers have started to fade and become not very pretty. Should I remove these faded flowers? If yes, how much should I cut?
Also some flowers started with Pink/blue but have changed into more white and light green. Did these flowers already run their course and should be removed? or they are part of the blooming cycle and should be left alone?
Thanks in advance for your help.
