Fall brings along an array of beautiful colors in our landscape. Have you ever wondered what these colors are, or why they happen?
As days become shorter and the temperatures become colder, this signals trees to prepare for winter by conserving energy. Chlorophyll, or the green pigment that absorbs sunlight to make food through photosynthesis, begins to break down and is no longer produced. This process is called senescence!
As chlorophyll breaks down, pigments called carotenoids become visible, giving us yellow and orange hues.
Some trees express vibrant red hues, known as anthocyanins. Anthocyanins, unlike carotenoids, are not already present as chlorophyll breaks down, but are newly produced.
As you admire the cozy colors of fall and prepare for the winter months, think about how trees are doing the same!🍂🍁
