I have a dozen or so hydrangeas in the front of our house that collect tons of leaves late fall and winter. I have two questions: 1) they haven’t been divided in 15 years- do I even start? They are huge and the thought of trying to divide them makes me move on to other things every year: 2) any ideas how to remove the leaves in the middle of them? Aside from risking loss of an eyeball and pulling each leaf out individually? Or maybe should I just leave them there? Thank you!!!
