About Fall / Autumn
Sept 20 : 02 days to Fall
Did you know that leaves change colors in the Fall because of decreasing amounts of a pigment called chlorophyll?
Chlorophyll, which converts air and water into food for plants, gives leaves their bright green color. The colder Fall temperatures decrease chlorophyll production.
Did you know that the pigment anthocyanin is responsible for bright red and purple leaves, while carotene brings out orange colors and xanthophylls makes the yellows?
These pigments are always present in the leaves, but only become dominant in the Fall, when the colder weather causes chlorophyll production to drop.
Do you feel that? The crisp morning air is a sure sign that the Fall season is right around the corner. As the days get shorter and the temperatures fall, Autumn heralds its coming with fiery red leaves and bright orange pumpkins.
