‘Sharpblue’ is a proven variety in southern states, introduced from the University of Florida in 1976. This bush bears dark blue dime-size berries that are sweet and high in antioxidants. An early season variety, it is a tough and vigorous bush with low chill requirements (150-250 chill hours). It is also self-pollinating. ‘Sharpblue’ blueberry plants are more resistant to rot and more adaptable to sandy soils than most other Southern Highbush varieties. Typically, fruit ripens by late May to early June and harvest may extend over 6 weeks. Prune heavily in the second year to stimulate strong new growth on selected canes.
Blueberries are growing in popularity due to their reliability and health attributes. Blueberries are extremely nutritious with antioxidants and high vitamin contents. They are also delicious in pies and make delicious jams and preserves. Best of all, bake your own Blueberry Muffins!
For best results, set plants out as early as possible in the spring. Prune branches back about 1/2 their length at planting time with no further pruning required the next 3 years. Prune annually thereafter during the dormant period. ‘Sharpblue’ blueberries may require protection from the spring frost. They are also self-fertile; however, they are more productive when planted with other blueberry plants.
