</p><p>Woodbending is theoretically possible if there is enough moisture in it, making it simply an extent of plantbending. But like Neo said, wood is not exactly a good element to weaponize, since it can easily be cut, snapped, burnt, or otherwise destroyed by any of the elements, and its rigidity (and relative scarcity) only makes it good for certain weapons.
