White OakQuercus alba
The white oak is a large, strong, imposing specimen. It has a short stocky trunk with massive horizontial limbs.The wide spreading branches form an upright, broad-rounded crown. The bark is light ashy gray, scaly or shallow furrowed, variable in appearance, often broken into small, narrow, rectangular blocks and scales.The leaves are dark green to slightly blue-green in summer, brown and wine-red to orange-red in the fall. The fall foliage is showy. Oaks are wind pollinated. Acorns are produced generally when the trees are between 50-100 years old. Open-grown trees may produce acorns are early as 20 years. Good acorn crops are irregular and occur only every 4-10 years. The white oak prefers full sun, but has a moderate tolerance to partial shade. It is more shade tolerant in youth, and less tolerant as the tree grows larger. It can adapt to a variety of soil textures, but prefers deep, moist, well-drained sites. High pH soil will cause chlorosis. Older trees are very sensitive to construction disturbances. The deep tap root can make transplanting difficult. Transplant when young. New transplants should receive plenty of water and mulch beneath the canopy to eliminate grass competition. Old oaks on upland sites can be troubled by sudden competition from and excessive irrigation of newly planted lawns. Their root zones must be respected for them to remain healthy. White oak is less susceptible to oak wilt than the red oak species.
