SundayStills (Early signs of fall) Fall Colors
“How beautifully leaves grow old. How full of light and color are their last days”
Autumn is one of the four temperate seasons. Autumn marks the transition from summer into winter usually in September (Northern Hemisphere) or March (Southern Hemisphere) when the arrival of night becomes noticeably earlier. The nature exhibits its most amazing colors while the trees shed their leaves and hide the land with beauty of fall. Fall leaves decompose so that they can release their minerals back to the underlying soil. Composting fall leaves is an excellent way to improve yard & garden soils. Mixing green & brown materials together is the basic rule.
Maples, Oaks, Elms, Birch & Ash trees are just a few of the trees that give spectacular colors during the Autumn season. Bright red & purple colors come from anthocyanin pigments, like in maple leaves, are formed from trapped glucose. Brown colors come from a waste product called tannin, orange colors comes from carotene & the yellows from xanthophylls. The leave colors red, yellow & brown are in the leaves all year long & only become exposed when the green chlorophyll disappears in the fall.
