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 from hardwood cuttings in winter
Growing
Cultivated for their very rapid growth as specimen trees and useful for windbreaks. Tolerant of any soil other than constantly waterlogged soils. Avoid growing within 40m of buildings as the vigorous root systems may damage drains and foundations, particularly on clay soils. It has the potential to become a nuisance
