White Oak is a large, stately tree with a round to wide spreading crown, growing 50-70 ft. in height, and 40-80 ft in width. It is hardy to zone 3b. White Oak is is tolerant of a wide range of soils, best grown in well-drained soil, and because of its deep root system, is fairly drought tolerant once established. It has no serious disease or insect problems. The strong tap root makes this tree difficult to transplant, and existing trees are very sensitive to disturbances in their root zone.
