Q: Is it too late for blueberry pruning?
A: You can prune blueberries anytime between late fall and late winter. Actually, they require little pruning until they reach four to six feet in height. At this point, start a cane renewal pruning program. Remove one to three of the largest canes each winter, cutting at six to twenty-four inches from ground level or a total of about twenty 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 more will sprout below ground level. In addition, very tall canes can be pruned back to six feet each winter.
