Question:
Doc,
I have a sycamore tree in my backyard. The leaves started emerging earlier this month, but several have fallen off. There is a white suede-like substance covering the ones that have fallen. Any idea what this could be?

Doc’s Answer:
This disease is known as sycamore anthracnose. It attacks most sycamore species and is considered a chronic disease. It attacks the tree especially in cool moist springs.
If your tree is vigorous it will likely re-leaf in time for summer.
Repeated defoliation over the years can cause the trees decline. There are several therapies and medicaments available to control this disease. Often a simple fertilization is all that is needed.
