The main reason why trees shed their leaves is part of a strategy to survive upcoming harsh weather conditions.

At the beginning of this process, the tree will absorb some of the nutrients from the leaves and store them so they can be used later.

These large leaves require a significant amount of energy to maintain.Īs the weather changes and there is less daylight, hormones in deciduous trees let it know it is time to start the process to shed its leaves for the Winter. Evergreens can do this because most live in warm or wet areas, or they have narrow, weather resistant needles rather than large leaves that are present on deciduous trees. Evergreen trees are different and keep their green foliage year-round. In addition to being present in trees, xanthophyll is also found in squash and corn! Why do trees drop their leaves?ĭeciduous trees, such as ash, beech, elm, aspen, cherry, oak, maple, willow, poplar, and birch trees, shed their leaves each Fall to prepare for the Winter.
