Watering

Deep spaced watering sessions, mature trees handle dry soil well

Fertilizing

Balanced hardwood tree feed applied once yearly early spring time

Pruning

Little pruning is needed. Remove diseased, damaged, crowded or crossing shoots and unwanted growth. Timing depends on the plant: generally late winter or early spring; plants prone to bleeding and deciduous magnolias need different timing, and deciduous azaleas and lilacs are pruned after flowering.

Propagation

Propagate by seed in autumn

Growing

In cool climates such as the UK, needs a warm site with well-drained soil in a sunny position. In warmer climates, grow in deep fertile soil in partial shade
