Multiple-stem shrubs are rejuvenated by cutting back all the stems near ground level over a period of three years. The second year remove one half of the remaining old stems. Prune back long shoots from the previous year's growth. The third season remove the remaining old wood and head back the long new shoots. The best time for rejuvenation pruning is late winter or early spring.
Basic tools used in pruning are hand shears, loppers and hand saws.
Hand shears are used for general cleanup, loppers for branches up to 1 inches in diameter, and pruning saws for larger branches.
