- Description
-
Southern Red Oak is a native deciduous tree and is found in all areas of NC up to 2,000 ft. of elevation. It may grow 60 to 100 feet tall and spread 50-60 feet with a broad open rounded form. It is naturally found on poor upland mesic soils in much of eastern and central USA but also occasionally found along streams. It should be grown in full sun to part shade on well-drained, acidic, sandy loam, gravelly or clay loam soils. It is drought tolerant but will tolerate occasional flooding.
Acorns need 2 years to mature as is the norm for red oaks. There are 2 different types of leaves and they are tan and downy on the undersides which contrast nicely with the dark lustrous green on top, especially in the wind.
Use this tree for shade in parks and residential areas. Its drought tolerance makes it especially useful as a street tree. The acorns attract a variety of birds and mammals and like other native oaks, it is a high-value wildlife plant. It is a host plant for the larvae of the Imperial moth (Eacles imperialis), as well as numerous butterflies, including Banded hairstreak (Satyrium calanus), Edward's hairstreak (Satyrium edwardsii), Gray hairstreak (Strymon melinus), White-m hairstreak (Parrhasius malbum), Horace's duskywing (Erynnis horatius), and Juvenalis duskywing (Erynnis juvenalis).
Insects, Diseases, or Other Plant Problems: There is a large number of potential problems. Except for oak wilt, no pests or diseases are of major concern. Caterpillars can defoliate trees. Fall cankerworm has been a problem in some years. Banding the trees will help. This tree is susceptible to wind damage.

White-M Hairstreak (Parrhasius m-album) has three broods in the north from February-October. Horace’s Duskywing (Erynnis horatius) has three broods in Texas and the deep south from January-November, and two broods in the north from April-September. Juvenal’s Duskywing (Erynnis juvenalis) has one brood from April-June, appearing as early as January in Florida. The acorns are eaten by woodpeckers, blue jays, white-breasted nuthatches, American crows, small mammals, wild turkey, white-tailed deer and black bear.
