When Do Leaves Start to Fall?
Fall is when the days become a little shorter, and the nights start to cool. You can anticipate jacket and sweater weather. You can also expect falling leaves you will have to remove from your yard and gutters. But when do the leaves start falling?
What Causes Leaves to Fall?
A fall leaf drop is a form of self-protection. While evergreen plants in cold climates have thick waxy needles that protect them from freezing and fracturing, deciduous species have thin leaves that are vulnerable to cold temperatures. Since water expands when frozen, the fragile leaf cells would burst during the winter, making them useless for photosynthesis. Without dropping these leaves, a tree would be stuck with thousands of useless appendages and no way to make food!
And if that weren't a good enough reason, all those leaves' surface area would also threaten the plant's physical integrity. Winter months are windier than other seasons, and the wind against the broad leaves on a cold, brittle tree could cause significant breakage. The same goes for the weight of snow collecting on all those leaves.
Finally, by the end of summer, many leaves have been eaten by insects, are diseased, or damaged. Dropping leaves give the tree a new start in the spring, and the decaying leaves provide the tree with nutrients to help grow fresh leaves in the spring.
Fall leaves are not blown off trees but are separated from the plants in a unique process. As day length shortens and temperatures cool, hormones in the tree are activated to begin the removal process. Chlorophyll production stops, and the green pigment degrades, revealing bright reds and yellows. The vessels that carry water and sugars to the leaf and the rest of the tree are closed off, and a layer of cells, known as the abscission layer, starts to grow between the leaf stalk and the branch. These cells slowly cut the leaf from the tree without leaving an open wound. As the leaves fall, the tree enters dormancy, saving energy for new spring leaf growth.
Peak Fall Foliage
Leaves can change their color from as early as late September through early November. Typically, the peak times of October are the second and third weeks of October, but it shifts depending on where you live.
- Foliage starts to change in the northern-tier states out West and in the Midwest by late September; around the first week of October, the leaves in some areas will be in their prime.
- Much of New England and the Pacific Northwest will be at or near peak fall color by the second week of October.
- A bit further south in the Blue Ridge Mountains, mid-October is the general time frame.
It also depends on the weather in the region. The leaves could change as early as August if an area has had a hot, dry summer. Some tree species, particularly oaks and beeches, keep their leaves much longer than other trees. But after the leaves reach their peak color, they fall off the tree about a week later.
