What is the proper way to prune blueberries?
Early spring is the best time to prune blueberries. In Iowa, late March or early April would be an appropriate time to prune blueberries.
Young plants require little pruning. Pruning of young plants mainly consists of pruning out broken, dead, or diseased stems.
Blueberry yields and fruit quality decline when blueberry canes (stems) reach 5 or 6 years of age. After the fifth year, prune out 1 or 2 of the oldest stems. Also, allow 1 to 2 new shoots to develop. Continue to prune mature blueberry bushes in this manner on an annual basis to keep the plants vigorous and productive.
