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
