Why aren’t all the leaves dropping?
According to Walt Nelson of Cornell Cooperative Extension of Monroe County, Jack Frost and Mother Nature were confused this fall.
Summer-like weather extended into October, then the growing season ended abruptly with freezing temperatures in November.
An abscission layer of cells usually grows between the leaf stalk and twig, and makes it easier for the leaves to separate.
That abscission layer did not form this year, so the leaves are hanging on.
If the wind doesn’t tear them away, next year’s buds will push them from the tree.
Nelson believes there won’t be a long term impact on the health of the trees.
