Fertilizing

Balanced perennial feed every four weeks from spring through summer

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 semi-hardwood cuttings

Growing

Grow in moist but well-drained neutral to acid, moderately fertile soil, in full sun or partial shade. Suitable for woodlands or as a specimen tree. Full sun brings out the best autumn colour - see tree cultivation
