Red Oak (quercus rubra)

• North American deciduous tree, widely planted since 1724; fast-growing (faster than native oaks) reaching 25–35m tall with broad, rounded crown.
• Spectacular autumn colour: deeply lobed leaves turn brilliant scarlet-red in The Fall, often persisting late into the season.
• Highly tolerant of urban pollution, poor/dry soils, and some exposure; more adaptable than English oak on acidic or compacted sites.
• Produces acorns for wildlife (jays, squirrels, deer); supports insects and birds; excellent specimen for parks, avenues, or large gardens.
• Attractive fissured bark with age; wind-resistant once established; RHS Award of Garden Merit winner.
• Note: Can suffer chlorosis on very chalky soils; acorns less palatable to UK wildlife than native species.

Planting Guide

• Best time: Bare-root November–March (dormant season); container-grown autumn or spring.
• Location: Full sun to partial shade; deep, moist but well-drained, preferably acidic to neutral soil (tolerates clay/loam but dislikes shallow chalk); requires vast space – unsuitable for small gardens (mature spread 15–25m+).
• Preparation: Dig large hole twice root width; incorporate organic matter in poor soils.
• Planting: Set at original depth (check trunk soil mark); stake young trees; firm in, water well, mulch base (keep clear of trunk) to reduce weed growth and conserve soil moisture.
• Aftercare: Water regularly first few years in dry spells; minimal pruning (remove dead/damaged in winter); protect young trees from rabbitsand deer.
