Overview
Northern red oak (Quercus rubra) is a large, vigorous deciduous tree native to eastern and central North America. It is among the faster-growing oaks and tolerates a wide range of conditions, making it a popular street and shade tree.
A member of the red oak group, it has leaves with pointed, bristle-tipped lobes and acorns that take two years to mature. Its handsome, strong wood is one of the most commercially important hardwoods in North America.
How to identify it
- Leaves: Alternate, with 7-11 pointed lobes ending in bristle tips and shallow, U-shaped sinuses; dull green turning brownish-red to red in fall
- Bark: Dark gray-brown with smooth, flat-topped ridges often described as 'ski trails' running down the trunk
- Acorns: Rounded acorns with a shallow, flat, saucer-like cap; maturing over two years
- Form: Rounded crown, 60-90 ft tall, often fast-growing
- Buds: Reddish-brown, pointed, clustered at twig tips
Care & growing
Light: Full sun.
Water: Moderate; prefers well-drained soil but adapts to a range of moisture.
Soil: Tolerant of many soils, doing best in deep, slightly acidic loam; more pollution- and urban-tolerant than many oaks.
Temperature: Hardy USDA zones 3-8.
Feeding: Rarely necessary.
Propagation: Grown from acorns sown in fall; transplants more readily than white oak. Prune in dormancy to reduce oak wilt risk.
Habitat & origin
Northern red oak ranges across eastern and central North America from Canada to the southern Appalachians. It grows in upland forests, slopes, and well-drained valleys, often in mixed hardwood stands.
Because of its fast growth and urban tolerance, it is widely planted along streets and in parks far beyond its native range.
