What causes the leaves on trees to change color?
You may recall from science class that chlorophyll in leaves gives them their green color. When trees stop making cholorphyll, the green color is replaced with the brilliant, colorful leaves of fall. Nature’s signal to the trees to stop producing chlorophyll is warm, sunny days, and increasingly longer, cool nights. The brilliance of colors is influenced by weather from spring to fall, with temperatures and amount of rainfall playing a key role. Gardener’s: don’t discard those leaves in the trash. They contain lots of nutrients to replenish your garden soil.
