Choose a variety of blueberry bush that grows well in zone 3, such as blue ray, blue crop, patriot or spartan, which can survive in the colder winters of the zone.
Pick a location for planting your blueberry bushes in your yard that is in full sun and has well-drained soil.
Purchase a home soil test kit to make sure your soil has the appropriate pH level. Adjust the soil by adding peat moss or compost if necessary. Make adjustments to the soil at least three or four months before planting your new blueberry plants.
Buy 2 to 3 year old blueberry canes from a reputable grower, whether locally or from an online dealer. Look for guarantees that offer the return of your money if the plant does not last a year.
Plant the blueberries as soon as you buy them, as they are only available at the proper planting time, which is late April or early May in Zone 3.
Dig a hole 12 inches deep. Build a mound of dirt in the middle of the hole and spread out the roots out over the mound. Cover the roots with soil as well as 6 to 8 inches of the stem of the bush to hold it in the soil firmly.
Trim two-thirds of the height of the blueberry bush. Cut off any blossoms to prevent your bush from producing fruit the first year so it can take in nutrients and develop a strong root system and main stem.
Plant other blueberry bushes from 4 to 5 feet apart to allow room for them to grow.
