River Birch Tree Has Pink Colored Spots On Some Leaves

Question From: S. Heilman - West Bloomfield Township, Michigan, United States
Q: My River Birch tree has pink colored spots on some of the leaves. Could this be fungal?

A: I recommend you take a sample to English Gardens and talk to Daryl Younguest. If it were my tree I would have an onsite inspection from a certified arborist. Best And Happy Yardening, Nancy.
