When Do Acorns Fall Off of Oak Trees?
More than 50 different species of oak trees grow throughout the United States. Acorns, the large seeds of these trees, consist of up to 25 percent fat and can last for months without rotting, making them ideal for consumption by many animals. Does this Spark an idea?

Season
-
Acorns fall off oak trees in the autumn. Animals such as squirrels depend on the ripe acorns of fall for food to store and eat over the long winter months ahead. Other animals, including the bear, eat acorns from the forest floor, preparing themselves for hibernation.
Masting
-
Some trees, including the oak, produce large quantities of seed in one year, followed by poor production the following year, according to the Hastings Natural History Reservation.These years of abundant production are known as mast years. Acorns may cover the area around an oak tree several inches deep in a mast year, but produce only a couple handfuls of acorns another year.

Weather
-
Storms and strong winds often knock unripened acorns to the ground before the fall season begins. According to the Texas Cooperative Extension, these green acorns contain chemicals known as tannins that prove problematic for farmers and ranchers, whose cattle tend to eat them in large quantity and become ill.
Gathering
-
The best time to gather acorns is in the early fall, when they still hang on the trees and are just starting to drop. Choose brown acorns from the tree instead of picking them up from the ground where they may have been cracked and dried out.
