Quercus rubra
red oak
One of the faster-growing oaks with dark green, sharply lobed leaves which turn attractive shades of red, yellow and brown before falling in autumn. An attractive tree that is capable of adapting to most conditions, including industrial areas, though it does require lime-free soil. Reaching an impressive height and spread, Quercus rubra delivers an autumn colour masterclass for larger gardens and parklands.
How to care for Quercus rubra:
Plant in deep, fertile, well-drained soil in a sunny position, avoiding areas prone to waterlogging. When planting, incorporate organic matter into the backfill and firm the soil gently around the roots. Water well after planting and throughout dry periods until well established, typically within the first two to three years.
Young trees benefit from staking to prevent wind rock; use a sturdy stake and soft tie, positioning it low to allow natural trunk movement and remove once the tree is stable. Prune in late winter or midsummer to avoid sap bleeding, removing any dead, diseased, or poorly placed branches to create a strong framework.
As the tree matures, minimal pruning is needed beyond occasional maintenance. Each spring, mulch around the base with compost or leaf mould to retain moisture and improve soil structure.
