Pruning shrubs in August or early September may encourage a late flush of growth. This new growth may not harden sufficiently before the arrival of cold weather and be susceptible to winter injury.
Spring flowering shrubs (Table 1) bloom on last season’s growth; prune them soon after they bloom to promote vigorous summer growth. Some shrubs that bloom after June (Table 2) do so from buds that are formed on the current year’s shoots; prune these shrubs in late winter to promote vigorous spring shoot growth. Table 1.
