Why leaves change in Autumn

Why leaves change in Autumn
Fall is a delightful mix of warm days and crisp nights: perfect for fall foliage. Leaves are green, thanks to trees producing chlorophyll. When nights grow longer and colder, chlorophyll production slows down and eventually stops. The warm weather encourages the red and purple anthocyanins and orange-yellow carotenoids in the leaves to show through, creating the palette of brilliant colours.
