Deciduous trees shed their leaves as an active process that evolved to conserve resources and protect the tree from being blown over in the windier winter months. The process is controlled by the plant hormone auxin.

Trees prepare to shed leaves by growing a layer of cells between the leaf stem and the tree branch. Mar 04, Broadleaf, deciduous trees lose their leaves in the winter to reduce water loss inside the trunk and branches.
