When attempting to save an old oak on a construction site, leave the area within the drip line totally undisturbed, as white oak is highly sensitive to disturbance. Prune in winter or early spring. Remove dead or damaged wood any time of year. Leaves are glossy. Fall leaf color is yellow.
Leaves persist late into fall and winter.
Acorns are abundant and provide food for wildlife. Water oaks are used as shade trees, in buffer strips and along highways. They are adapted to wet, swampy areas, such as along stream banks and ponds, but they tolerate most well-drained sites. They prefer slightly alkaline to acidic soils and sun or partial shade. They transplant easily.
