Many if not all of the sycamore trees in my town (University Park) and nearby towns seem to be really struggling (the leaves are mostly brown and much smaller than they usually are). Is there some sort of blight or is it just a result of the strange spring weather? Is there anything that can be done to help them?

This cool damp spring has been perfect for a fungal disease known as anthracnose, and sycamore have been particularly hard hit. They look like they are on death's door, but fortunately this is a native disease which has co-evolved with our native sycamores and and sycamore are able to handle it. The sycamores may lose many leaves, but they have the ability to put out a new flush of growth and be just fine.

There are many types of anthracnose. Many species of shade trees get anthracnose, such as oak, ash or elm, and they each get their own type. We've been getting many inquiries about it the past two weeks.
