As summer ends and autumn comes, the days get shorter and shorter. This is how the trees "know" to begin getting ready for winter.
As the bright green fades away, we begin to see yellow and orange colors. Small amounts of these colors have been in the leaves all along. We just
can't see them in the summer, because they are covered up by the green chlorophyll.
The bright reds and purples we see in leaves are made mostly in the fall. In some trees, like maples, glucose is trapped in the leaves after
photosynthesis stops. Sunlight and the cool nights of autumn cause the leaves turn this glucose into a red color.
The brown color of trees like oaks is made from wastes left in the leaves.
It is the combination of all these things that make the beautiful fall foliage colors we enjoy each year.
And with fall comes the start of the hunting season!
God I love Colorado in the fall.
