This collection offers three northern highbush blueberries: Patriot, Spartan and Jersey. These are high-chill requirement varieties widely planted throughout the northern US and southern Canada. We have selected three that will produce continuously over a 90-day period. Northern highbush varieties need 800 chilling hours for good fruit set. "Chill requirement" refers to the accumulated hours of temperatures a plant experiences between freezing and 45 F that is required to break dormancy.
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.
