White oak is an excellent ornamental tree because of its broad round crown, dense foliage, and purplish-red to violet-purple fall color. Acorns are eaten by squirrels, blue jays, crows, deer, turkey, quail, mice, chipmunks, ducks and raccoons.
White oak flowers in the spring at about the same time leaves appear. Acorn maturity is reached approximately 120 days after pollination. Acorn drop follows 25 days later and is complete within a month. Physiological maturity, as indicated by normal germination, is reached when acorns change color from green to light brown. Acorns germinate almost immediately after falling to the ground in September or October.
White oak grows at a slow to medium rate, with height increases of anywhere from less than 12″ to 24″ per year. Full sun and partial shade are best for this tree, meaning it prefers a minimum of 4 hours of direct, unfiltered sunlight each day.
White oak acorns are one of the best sources of food for wildlife and are gathered, hoarded and eaten by birds, hoofed browsers and rodents. Leaf buds also are eaten by several bird species, and all parts of the tree are a favorite food for deer.
The white oak prefers slightly acidic to neutral, deep, moist, well-drained soil. While adaptable to other soil textures, it is intolerant of alkaline, shallow or abused urban soils. It can, however, tolerate moderate drought and occasional wet soil.
Full sun and partial shade are best for this tree. Mature Height 80′ and a spread of 50–80′.
