Blueberry ‘Duke’

Blueberries are extremely nutritious, as they are naturally high in antioxidants and vitamin content. They have a delicious, mildly tart flavor that makes them excellent in pies, jams, and preserves. Best of all, bake your own Blueberry Muffins! Blueberries are rapidly increasing in interest due to their reliability and health benefits. The ‘Duke’ berry is very firm and retains its fresh quality longer than most other varieties. It blooms late but ripens early, protecting blossoms from late frosts. ‘Duke’ is a heavy, consistent producer. It has upright growth but its branches will droop to the ground when laden with fruit. Medium to large light blue berries.

Blueberries are considered a beautiful productive hedge with spring flowering on dark green foliage, delicious fruit in summer and fiery red foliage for autumn color. The ‘Duke’ variety is vigorous and has dense foliage. 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.

Planting/Care Instructions +

Planting Instructions: Prepare the ground well before planting. Blueberries prefers 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. Add generous amounts of peat but no fertilizer when planting. 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 can protect fruit from birds with netting.
