Description

Northern Red Oak is a deciduous tree that may grow 60 to 90 feet tall. The tree has alternate leaves with 7 to 11 bristle-tipped lobes. The bark is smooth on young stems. As the tree ages, wide, flat-topped ridges and shallow furrows develop. The shallow furrows form a pattern resembling ski tracts. In spring, yellow-green, cylindrical, male flowers and small, green, female spikes mature. The tree produces a 3/4- to 1-inch acorn with a flat, thick cap which covers about 1/4 the nut. The acorn requires two growing seasons to reach maturity.

Northern red oak generally first bear fruits at 20-25 years but don’t produce acorns in abundance until 40-50 years. Acorns maturing in the second year.

This plant is tolerant of urban conditions including dry and acidic soil and air pollution. Commonly grows on mesic slopes and well-drained uplands, on lower and middle slopes, in coves, ravines or valley floors. Most commonly on N- and E- facing slopes, and on clay, loam, and sandy or gravelly soils. It sustains best growth in full sunlight with well drained, slightly acidic, sandy loam.

Fire Risk: This plant has a low flammability rating.

Insects, Diseases, or Other Plant Problems:  Susceptible to oak wilt and chlorosis (yellowing of the leaves while the veins remain green) which can occur when soil is not sufficiently acidic.
