How to Grow Highbush Blueberry 'Jersey'

Highbush Blueberry 'Jersey'

Vaccinium corymbosum 'Jersey'

shrub

'Jersey' is a highbush blueberry cultivar prized for its large, firm berries and excellent flavor. It is a mid-to-late season variety that produces abundant crops and is particularly cold-hardy among highbush types. This deciduous shrub grows 6-8 feet tall and is ideal for both commercial and home gardens.

Growing Conditions

☀️

Sun: Full sun, 6-8 hours daily minimum; 8+ hours preferred for best fruiting

💧

Water: Consistent moisture, 1-2 inches per week during growing season; keep soil evenly moist but not waterlogged. Mulch heavily to retain moisture and maintain cool root zone.

📏

Spacing: 48 inches

📅

Days to maturity: Blueberries fruit year 3-4 after planting; 'Jersey' reaches full production by year 5-6

🌱

Planting depth: Plant at same depth as root ball; crown should be at or slightly above soil surface

Soil

Type: Well-draining, acidic sandy loam or peat-based soil

pH: 4.5-5.5

Amendments:

Peat moss pine bark sulfur (to lower pH if needed) compost coffee grounds

Growth Stages

Establishment (Year 1-2)

2 years

New plant develops root system and vegetative growth. Limited or no fruit production expected.

Remove flowers first 1-2 years to encourage root and branch development. Water deeply and regularly. Mulch with 2-3 inches of pine needles or bark.

Early Fruiting (Year 3-4)

1-2 years

Plant begins producing flowers in spring and initial berry clusters form.

Allow some fruiting but continue removing some flower clusters to balance fruit set with plant vigor. Ensure consistent watering. Apply balanced fertilizer (rhododendron formula preferred).

Flowering (Spring)

3-4 weeks

Delicate pink or white bell-shaped flowers appear in clusters along branches, typically March-May depending on zone.

Protect from late spring frosts if possible. Ensure adequate bee activity for pollination. Do not fertilize during flowering.

Fruit Development & Ripening (June-August)

6-8 weeks

Green berries develop and gradually ripen to blue, becoming larger and sweeter over 6-8 weeks. 'Jersey' produces large, firm berries.

Maintain consistent watering; irregular moisture causes soft fruit and cracking. Do not pick until fully blue (berries ripen over time after turning blue).

Dormancy (Fall-Winter)

3-4 months

Leaves turn red/orange in fall before dropping. Plant becomes dormant, requiring winter chill hours (800+ hours below 45°F for 'Jersey').

No active care needed. Light pruning acceptable. 'Jersey' is cold-hardy and tolerates temperatures to -20°F or below.

Plant with:

Rhododendrons Azaleas Serviceberry Highbush blueberry 'Duke' Highbush blueberry 'Bluecrop' Lingonberry Winterberry holly Heathers

Avoid planting near:

Alkaline-loving plants (lilacs, clematis) Black walnut (produces growth-inhibiting juglone) Plants requiring neutral-to-alkaline soil

Common Pests

Monitor with sticky traps starting late June; remove and destroy infested fruit; use spinosad spray if populations high
Remove infested leaves; maintain plant vigor; prune affected branches in winter
Hand-pick early morning; use pheromone traps away from plants; apply neem oil or spinosad if severe
Remove and destroy infected fruit (mummified berries); rake up and destroy fallen leaves; thin for air circulation; fungicide spray at bud break if history of disease
Prune out dead or diseased canes; improve air circulation; avoid overhead watering; disinfect pruning tools

Uses

🍳

Fresh eating and baking

Culinary

'Jersey' berries are large, flavorful, and firm, making them excellent for eating fresh, in pies, muffins, jams, and preserves. They freeze exceptionally well for year-round use. [source]

💊

Antioxidant and anti-inflammatory benefits

Medicinal

Blueberries are rich in anthocyanins and other polyphenols with potential anti-inflammatory, antioxidant, and cognitive benefits. Often promoted for eye health and overall wellness. [source]

🏠

Natural dye

Household

Blueberry juice has been traditionally used as a natural dye for textiles and food coloring, producing blue and purple hues. [source]

🦋

Wildlife food source

Wildlife

Berries attract birds, deer, and beneficial insects; flowers support early-season pollinators like bees and native bee species. [source]

🌿

Landscape interest

Ornamental

'Jersey' provides year-round visual interest with spring flowers, summer fruit, and striking fall foliage that turns deep red and orange. [source]

Harvest Tips

Pick berries when fully blue (small berries may ripen 3-5 days after turning blue); they do not ripen further after picking. Gently roll berries in hand—ripe berries detach easily with minimal handling. Harvest June-August depending on zone. 'Jersey' typically peaks mid-to-late season (July-August in zone 5). A mature 'Jersey' plant yields 10-15 pounds of berries annually.

Fun Facts

🌱 'Jersey' was released by the USDA and Rutgers University in 1942 and remains one of the most reliable and widely planted highbush blueberry varieties almost 80 years later.
🌱 Blueberries require cross-pollination with a different highbush variety for best fruit set; planting 'Jersey' with 'Duke' or 'Bluecrop' increases yields by 25-50%.
🌱 'Jersey' berries are notably firmer than many blueberry varieties, making them ideal for long-distance shipping, commercial markets, and home storage.
