Part of the tree's natural growth process in spring and summer, is to bring chlorophyll to its leaves. This gives them a green appearance.
In autumn, weather cools and the hours of daily sunlight decreases in many areas of the U.S. That's a signal for certain plants to gradually stop production of chlorophyll—a necessary component of photosynthesis.
Photosynthesis only occurs in the presence of warmth and sunshine, which of course become increasingly scarce starting in late September.
As chlorophyll production stops, the green leaf color fades. Colorful ﬂavonoids and carotenoids in the natural pigment of various leaf species sport yellow, orange, red, and purple coloration.
