After establishment, rabbiteye blueberries require little pruning until they reach about 6 feet to 8 feet in height. At this point, a cane renewal pruning program should be started. Remove one to three of the largest canes each winter at zero inches to 24 inches from ground level or a total of about 20 percent of the canopy. Over a period of five years the bush will be totally renewed. New, more productive canes will sprout from the old canes and will sprout below ground level. In addition, excessively tall canes can be pruned back to 6 to 8 feet each winter.
