Northblue Blueberry (Mid Harvest)

Northblue is a cold-hardy half-high blueberry developed by the University of Minnesota for northern gardens. The productive, compact plant bears midseason fruit with large size, dark-blue color, firm texture, and a tart blueberry flavor.

Pollination

Plant more than one compatible blueberry cultivar for more effective pollination and improved berry size and yield. Polaris is another cold-hardy half-high cultivar that matures earlier than Northblue.

Planting and Care

Choose full sun and acidic, well-drained soil, ideally around pH 4.5–5.5. Keep the shallow root system evenly moist and mulched. Northblue’s compact habit suits smaller gardens and containers, provided the roots receive winter protection and the potting mix stays acidic.
