Why do leaves fall off plants and how does it happen? First, all plants shed their leaves. The most obvious are the so-called deciduous trees like pecans, sycamores, cypress, tupelo, and elm, all of which shed all their leaves at once in the late fall. Others, such as magnolia, live oak, and wax myrtle, are non-deciduous and shed their leaves as each leaf reaches old age, though many oaks have two times during the year when they drop a lot of leaves during a short period of time.
