Summary
An exceptionally early blueberry known for delivering strong first harvests and, in warmer climates, an impressive encore crop.
Vaccinium corymbosum ‘Sweetheart’ is valued for its large, firm berries and reliable early-season production. In USDA Zones 4–8, it produces a generous early crop. In warmer regions, plants may produce a second, lighter late-season harvest under favorable growing conditions.
Beyond fruit production, this selection offers ornamental appeal with delicate white spring flowers and an attractive shrub form suitable for edible landscapes or mixed borders. Its firm texture and balanced sweetness make it well suited for fresh eating, freezing, and baking.
While self-fertile, planting more than one highbush blueberry variety nearby may improve overall yield and fruit size.
Care
Vaccinium corymbosum ‘Sweetheart’ Care
Plant in full sun for best fruit production and overall plant vigor.
Blueberries require acidic, well-draining soil rich in organic matter. Consistent moisture is important, especially during fruit development. Avoid waterlogged conditions.
Mulching around the base helps retain soil moisture, regulate temperature, and suppress weeds.
Fertilize in early spring using a
slow release fertilizer
formulated for acid-loving plants, following label directions.
Prune in late winter while dormant to remove older wood and encourage vigorous new fruiting growth.
Container Growing Notes: Blueberries can be grown successfully in large containers using acidic potting media. Containers require more frequent watering than in-ground plantings and must provide excellent drainage.
Plants hardy in the ground may require winter protection when grown in containers in colder zones.
