Both my hydrangeas have leaf spots. It is now fall, and I'm wondering if it's ok to remove all of the leaves with spots. It will leave the plant pretty bare. What should I do?

Hi ssaxe, I have noticed mine gets black spots every fall but I don't worry about it, I dont even cut them off anymore! Come spring theres new leaves that look healthy and green and stay like that until fall arrives again, I believe its called tar spot, a fungal infection that causes premiture leaf drop but does not affect the long term vigour of the plant. I live beside a forest and the sycamore trees are heavily infected with tar spot at this time of year and they will still be there this time next year so I wouldn't worry about it too much! But just incase you may actually have a problem you should post a pic!
