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 seed at 13-18°C in spring and summer
Growing
Grow in fertile, well-drained, neutral to acid soil in full sun with shelter from cold winds. Grow tender species outdoors in mild or frost-free counties only. See eucalyptus cultivation
