Yup! Depending on the species some immediately fell off. I have a tulip tree that dropped all its leaves on Saturday. My silver maples are still holding crinkled green leaves.
Forget about Oaks, I expect some of them to hold green/brown leaves that died in place. Could be an issue if we have an early season wet snow storm before the winter winds eventually strip them down.
i have never seen anything like it on campus. We were progressing like a normal fall just a week late. Since the majority of the big trees are oaks it’s almost as if fall stopped. The leaves are all stuck up in the trees!
