Why Do The Leaves Change Each Autumn?
Ever wonder why the leaves turn color in the fall?
The Autumnal Equinox occurs at 10:49 a.m. on Saturday, September 22.
It’s the cooler temperatures each fall that trigger leaves to stop producing food for the tree. Our resident weather expert at the station, Rich, told me that at 43 degrees Fahrenheit, photosynthesis stops and decay begins.
The chlorophyll in the leaves that had been turning sunlight into energy goes dormant during the winter months, so the green color fades away and sometimes the amount of glucose that was left in the leaf, determines what color it turns.
Enough of a science lesson, let the fall begin. If you have any great pictures of nature’s Autumn splendor, post them here for all of us to enjoy.
