Quercus robur
common oak ( syn. Quercus pedunculata )
A majestic tree with dark green, irregular, rounded-lobed leaves and clusters of neat acorns sitting in nobbly cups. Oaks are steeped in history, hiding legendary figures, such as Robin Hood and King Charles II in their sizeable trunks. Known for their large size and longevity, Quercus robur should be planted for prosperity. They tolerate most soils, except shallow soil, and in large gardens and parks are ideal as specimen trees.
How to care for Quercus robur:
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.
