Fall Leaves Turn Color in the Fall

Vermont's fall foliage is one of the most famous in the U.S. The trees are triggered by the shortening day length to say, we got to get ready for winter because we're going to drop our leaves. When the chlorophyll stops being made, the green color dissipates and that kind of unmasks the yellow and orange colors. As the reds begin to develop during the fall season, another process is happening where the leaf is actually forming a boundary between where the leaf attaches,. And that's signaling kind of the last roll for the leaf before the wind or rain might blow it or push it off the twig.
