Red Oak

Red Oak

Red Oak, or Quercus rubra, is a beloved native hardwood that delivers year-round interest and environmental value. Known for its stately structure, fast growth, and classic oak leaves, it reaches 60–75 feet tall and 50–60 feet wide at maturity, forming a rounded to broadly oval crown. Its smooth, dark gray bark develops distinctive ridges with age, while its deeply lobed leaves provide dense summer shade and turn vibrant red to reddish-brown in the fall.

This oak is highly adaptable to a range of soil types from sandy loam to heavy clay, as long as drainage is adequate. It prefers acidic soils and performs best in full sun. Red Oak is often used in parks, campuses, large yards, and restoration projects thanks to its durability, beauty, and ecological importance. It supports a wide array of pollinators, birds, and mammals, especially through its acorn production in autumn.

A true keystone species, Red Oak contributes to soil stability, improves biodiversity, and offers an enduring legacy in the landscape. With minimal maintenance and a high tolerance for urban conditions, it’s an ideal tree for those seeking long-term shade, structure, and wildlife benefit.

Planting: Plant in spring or fall in a location with full sun and ample space for its mature canopy. Dig a hole 2–3 times the width of the root ball. Ensure the root flare is at soil level. Backfill with native soil, water deeply, and mulch 2–3 inches around the base—keeping mulch away from the trunk.

Watering: Water deeply and regularly for the first 2–3 years, especially in dry periods. After establishment, Red Oak tolerates drought but still benefits from supplemental watering during prolonged dry spells.

Pruning: Prune in late fall or winter to shape the tree and remove dead or crossing branches. Avoid pruning during the growing season to reduce the risk of oak wilt.

Pest & Disease Management: Generally resilient, though susceptible to oak wilt, anthracnose, or leaf blister in some regions. Promote good airflow and avoid injury to the trunk or roots. Monitor acorn drop and clean up to prevent unwanted seedlings.

Soil Tips: Performs best in acidic, well-drained soils. Avoid poorly drained, compacted, or alkaline soils to prevent chlorosis (yellowing leaves).
