What Causes Autumn Leaves to Fall?

Many articles have been written about what causes leaves to change to those vibrant, eye-catching colors we’re accustomed to each year. It is a fascinating process to be sure. But after the appearance of those colors awe us for a time, the limbs become bare and uninviting for a period, too. So, what exactly causes autumn leaves to fall? There are several factors that play a role in this, and unlike the very scientific process that occurs when leaves change color, it may surprise you to learn that some of the causes behind the actual falling of the leaves are actually quite simple, albeit logical.

Perhaps one of the most common reasons leaves fall is wind. As the frequently blustery conditions of autumn and winter set in, leaves succumb to them. Obviously, the more powerful the wind, the more likely the leaves are to fall. If you live in a region that is naturally prone to high winds or blizzards (especially if they occur early in the season), then you are more likely to see the leaves fall earlier than other regions.

Likewise, precipitation may be responsible for causing the leaves to finally drop. This may include heavy rains, hail, snow or ice. Any form of precipitation that either falls heavily or bears significant weight as it accumulates on the tree will likely cause leaves to plunge.

Consider, too, that wildlife may also sometimes be responsible for falling leaves. Particularly, animals of flight and those that climb, such as birds and squirrels, become quite active during autumn as they make preparations for the onset of winter. They scurry about looking for food, shelter and other necessities. In doing so, they may unwittingly become the culprits responsible for finally sending trees’ leaves plummeting to the ground. Contact an Austin arborist or a wildlife specialist for ideas regarding how you can support wildlife during these increasingly sparse months without prematurely compromising the autumnal splendor of your landscaping trees.

The overall health of a landscaping tree is also a factor when it comes to dropping leaves. If a tree is unhealthy or dying, the affected parts are generally isolated from the physiological processes responsible for sustaining it. Certainly a dying branch can neither support itself nor any leaves. If you enjoy autumn’s brilliant colors and desire to prolong their presence on your landscape, contact an Austin tree trimming professional at the first indication of a problem to assist with the proper techniques necessary for dealing with dead or dying branches, thereby increasing the viability of your tree.

While some of the causes of falling leaves are unable to be prevented, some may be combated, even if only for a meager amount of additional time to take in autumn’s grandeur. Speak with an Austin tree care specialist about ways in which you may extend this annual experience in your own backyard.
