Everything To Know About Fall Foliage
Category : Tree Care
Trees are some of the biggest mysteries to the average person. One of the most defining moments of changing seasons from Summer to Fall is leaf color change in New England. Why does New England get to experience foliage, and how do these leaves end up changing from green to many different other colors each year? Why do some trees not change colors?
How Does The Color Change Happen?
During the spring and summer months, chlorophyll hides any other pigment that is on the leaves. So, the colors are there but are covered by the green. When fall comes around, trees will break down the green pigment, as well as the nutrients. The nutrients are stored back into the trunk of the tree for when spring comes around again. After these nutrients leave the leaves, their fall colors will show! Some leaves end up turning completely brown, which means all of the nutrients are gone.
Hardwood trees are the ones famous for their color-changing leaves. These trees are primarily found in New England and the Midwest. Many scientists believe that the colors the leaves take serve as a “sunscreen” to the tree, filtering out light. Although situated outdoors, trees can only take so much sun without any consequences. Like humans, leaves can be sunburnt and become damaged.
Rain Affects Leaf Color
The amount of rain that falls during the year will determine how well leaf colors appear to change during autumn. When it’s a warm and wet fall, there will be a lower intensity of lead colors. A harsh frost will kill the leaves and turn them brown, causing them to fall off the trees early. The best leaf colors appear when it’s a warm and wet spring or when the summer isn’t too dry.
Why Do Leaves Fall Off Their Trees?
The roots, branches, and trunks of trees can withhold the freezing fall and winter weather but leaves as lucky. As the sun sets early and rises later, the veins that hold the leaves to the branches begin to close, and the separation layer forms at the base of the stem. This causes the leaf to fall.
Why Don’t Evergreen Trees Change Colors?
Evergreen trees are forever-green, meaning they don’t change during the fall. Evergreen trees have needles that are coated in wax, and the fluids inside don’t allow them to freeze. These trees can go years without having fallen needles and leaves, and when that happens, they grow new ones.
