Red Oak Characteristics
Red Oak are common ornamental trees in Pennsylvania. They can be found in the wild or in highly landscapes yards. They are identifiable by the sharply multi-pointed leaves, acorns, and red fall color. Acorns may not become abundant until the trees are over 40 years old.
Red Oak are fast growing and can be long lived. They can be susceptible to a few diseases that can be serious, such as oak wilt and chlorosis. Unfortunately, oak wilt has no cure, but chlorosis occurs in soils that are too basic and require some acidity.
