High bush blueberries, the most frequently grown commercial plants, can produce for 40 to 50 years. They rely on generous amounts of water and well-drained soil. Started as cuttings in greenhouses, the young slips are planted in rows. Covered with mulch to maintain moisture levels, the plants can produce all summer. New Jersey raises the most cultivated fresh blueberries in the United States.
Maine produces only wild blueberries, much of the crop processed by freezing.
The U.S. produces over 110 tons of blueberries, Canada close to 40. Poland, Lithuania and the Netherlands are also significant blueberry growing countries.
