ORONO – The University of Maine Cooperative Extension has updated its classic publication explaining why leaves change color in autumn.
While some people believe frost causes the color explosion, some leaves begin to turn red, orange or yellow even before the first frost.
In Bulletin 7078, Facts About Leaf Color in Maine, UMaine Extension Professor Kathryn Hopkins explains the science of fall foliage. The bulletin also includes leaf projects that can be done at home and in the classroom.
For more information, bulletin copies for 50 cents each and free downloads, visitextensionpubs.umext.maine.edu/ or contact 207-581-3792 or [email protected].
