Fertilizing

Balanced shrub feed once in 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. Trim hedges in early spring.

Propagation

Propagate by semi-ripe cuttings in late summer or early autumn or propagate by hardwood cuttings in January with bottom heat

Growing

Grow in moist but well-drained, preferably neutral to acid soil in full sun or part shade. Not suited to chalky soils
