Fertilizing

Balanced shrub or tree feed once each early spring

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 soon after it drops or by semi-ripe cuttings in late summer

Growing

Suited to large gardens and parkland. Grow in any well-drained but moisture-retentive soil in good light. For more information see tree cultivation.
