Watering

Moderate regular watering, avoid prolonged drought and stagnant waterlogging

Fertilizing

Balanced perennial feed every four weeks spring through summer growth

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 softwood cuttings in late spring, by semi-ripe cuttings in summer, or by layering in spring or autumn

Growing

Grow in neutral, well-drained soil, in full sun, in a warm position such as a south-facing or west-facing wall to encourage flowering, and protect roots in winter with an organic mulch
