How to Prune engraved cotoneaster?
For free-standing plants: 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. For wall-trained specimens: On established wall-trained shrubs, shorten sideshoots to two to four buds from the framework; remove shoots growing towards the wall. Prune annually after flowering on last-year growth, or in late winter or early spring on current-year growth.
