Post Oak

Description

Post Oak is a deciduous tree that may grow 40 to 50 feet tall and is common in poorer soils but is also found in the mountains to an elevation of 2,500 feet. It is native to central and eastern USA. It has a dense rounded to irregular form with the upper branches and stems often being twisted and gnarled. The tree has alternate leaves with 5 lobes and a hairy, pale underside. The two middle lobes are distinctly square, resulting in an overall cruciform appearance. 

Post Oak is tolerant of various soil types and prefers acidic well-drained soil in full sun. It is resistant to drought, fire and diseases. Use in the lawn as a shade tree, in naturalized areas or as a street tree. Oak trees will attract a variety of birds, moths, butterflies and mammals to your yard, providing them with food and shelter.

Insects, Diseases, and Other Plant Problems: No pests or diseases of major concern but the tree occasionally succumbs to Chestnut blight and is susceptible to oak wilt.
