It's easy to misidentify trees that appear to be maple trees due to similarities in leaf shapes. Sweetgum, sycamore, and yellow poplar all have leaf shapes and appearances similar to maples. The fact that around a dozen maple tree varieties exist, only about half of which are considered common, makes misidentification an often typical occurrence.  

It depends on where you live—but in most areas, leaves begin falling in September and continue falling until January or February. Warmer regions, such as Southern states, may see leaves fall a bit later in the calendar year. It also depends on the type of trees in your yard and their maturity. 

If a tree stump is removed properly, the chances of a tree growing back are low. However, if a tree has a robust root system, roots can sometimes sprout and someday grow into a tree. The chance of regrowth will depend on several factors such as the type of tree, soil quality, and strength of the root system. In general, it is not recommended to plant a tree where a stump was removed.

You will know that an oak tree needs to be removed when you see vertical cracks or dead branch stubs, which indicate internal decay. Other signs include trunk rot near the base of the tree and sprouts or small branches coming from the trunk.
