Blueberry ‘Sharpblue’

‘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.

Planting/Care Instructions +

Planting Instructions: Prepare the ground well before planting. Blueberries prefer an acid soil. In alkaline soil, add ammonium sulfate for best results. Dig a hole large enough to encompass the roots without bending or circling. Set the plant in place so the crown (part of the plant where the root meets the stem) is about 1-2 inches below the soil surface. When planting, add generous amounts of peat but no fertilizer. Cover with soil to the original soil surface and water thoroughly. Blueberries can also be grown in large pots and containers if compost is used. Prune in winter, cutting out dead or damaged branches. In spring, feed with sulphate of ammonia, sulphate of potash, bonemeal and top-dress with compost.

Pests or Diseases: No serious insect or disease problems. You may protect your fruit from birds with netting.
