Description

Premium Sweetheart Blueberry Bush (Vaccinium corymbosum 'Sweetheart') is a remarkable variety that brings an extended harvest window to your garden. Known for its ability to produce two distinct crops in a single growing season—one in early summer and a second in late summer—it is a favorite among those who value both high productivity and exceptional fruit flavor. Establishing your berry patch with a 1-2 ft. starter bush allows you to cultivate this plant's root system in your specific soil conditions, fostering the long-term vigor and resilience needed for such an intense fruiting schedule. This foundation is key to ensuring your Sweetheart Blueberry matures into a heavy-bearing, healthy centerpiece that provides double the enjoyment throughout the summer months.

Growth Rate & Habit

Sweetheart Blueberry is a vigorous, upright grower that forms a dense, well-branched shrub. Its foliage is an attractive, deep green, providing a lush background that looks beautiful even when not in fruit. The bush is exceptionally productive and maintains a manageable shape, making it easy to incorporate into mixed ornamental borders, vegetable patches, or dedicated fruit-producing rows. Regular, light pruning in late winter helps maintain an airy canopy, which is crucial for encouraging that signature second harvest.

Harvest & Fruit Quality

The fruit of the Sweetheart Blueberry is highly prized for its firm texture, excellent size, and perfectly balanced, sweet flavor. The berries are aromatic and hold their quality exceptionally well, making them ideal for both fresh eating and a variety of culinary uses. Because it is self-fertile, a single bush will yield a bountiful harvest, though planting near another blueberry variety will often lead to even larger and more consistent production for both crop cycles.

Watering and Feeding

Like all blueberries, Sweetheart requires acidic, organic-rich, well-draining soil (pH 4.5 - 5.5). Maintain consistent soil moisture, particularly as the berries begin to size up for both harvests. A deep, focused soak once a week at the base of the plant is standard practice. Feed with an acid-loving fertilizer (formulated for blueberries) in early spring as new growth emerges, and again mid-summer to provide the energy required to support the second production cycle.

Light & Hardiness

To maximize the sweetness of its two harvests, ensure Sweetheart receives full sun—aim for at least 6 to 8 hours of direct, unobstructed sunlight daily. This light exposure is essential for building the energy reserves needed for its double-crop habit. Reliably hardy in USDA Zones 5-8, this cultivar is a resilient, cold-hardy performer that thrives in environments with a distinct winter dormancy period, returning with renewed, high-performance vigor every spring.
