White Oak
Quercus alba

Description

Quercus alba, or white oak, is native to eastern and central North America, ranging from southern Maine and Quebec west to Minnesota, south to Texas, and east to Florida. It is best grown in rich, moist, acidic, well-drained loams in full sun, though it adapts well to a variety of soil conditions and is drought tolerant. This long-lived tree is commonly used as a large shade tree, street tree, or lawn tree but requires ample space for growth. They are very slow growing when young, difficult to transplant and not tolerant of alkaline and fine textured soil. Its acorns ripen in fall, which can be a litter issue near sidewalks and patios. Pruning should be done in the dormant season to avoid attracting beetles that carry oak wilt. Quercus alba drops large acorns and a substantial number of leaves, with the heaviest shedding in the fall. It is considered moderately messy due to the acorn litter and the seasonal leaf drop that requires regular cleanup.
