Photo by Jeremy Baucom (Flickr Creative Commons) In the fall, trees put on a pretty impressive fashion show. It all starts inside the leaf. Chlorophyll (greens) Xanthophylls (yellows) Carotenoids (oranges) Anthocyanins (reds) Leaves are green in the spring and summer because that’s when they are making lots of chlorophyll. The summer sunlight triggers the leaves to keep making more chlorophyll. As summer fades into fall, the days start getting shorter and there is less sunlight. Shorter days in the fall are a signal for trees to start preparing for winter. Weather is also an important part of the color change. Extreme weather changes can also have an effect on the leaves. So if you want to know how long the colors will last this fall, be sure to keep an eye on the weather!
