Northblue is a great landscape plant and super producer of quality fruit in very cold climates. The fruit has a “wild” taste, juicy and is excellent for baking or fresh eating. Northblue has survived winter temperatures to minus 35°F, although will thrive best when snow protection is adequate. Fall foliage is red-burgundy blooming in white during the spring. Northern highbush blueberries require 800 to 1000 chill hours to set fruit.
Plant blueberry plants in a sunny to partially shaded area, in a well-drained, very acidic soil, with a pH of 4.2-5.2. Plant at least two different varieties for cross pollination. Set blueberry plants 4-8 feet apart (3 feet apart for hedges).
As fruit ripens, cover blueberry plants with netting to deter birds. Pick fruit promptly to discourage insects.
