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.
