How to Grow Lowbush Blueberry 'Weymouth'

Lowbush Blueberry 'Weymouth'

Vaccinium angustifolium 'Weymouth'

shrub

Weymouth is a cold-hardy lowbush blueberry cultivar prized for its early ripening, high yields, and excellent flavor. This deciduous shrub grows 12-24 inches tall and produces abundant clusters of small blue berries in mid-summer. It's valued both for commercial production and home gardening in cold climates.

Growing Conditions

☀️

Sun: Full sun, 6-8 hours daily; tolerates partial shade

💧

Water: Consistent moisture (1-2 inches weekly); avoid waterlogging. More drought-tolerant than highbush varieties once established.

📏

Spacing: 12-24 inches

📅

Days to maturity: 180-240 (3-4 years to significant production)

🌱

Planting depth: Same depth as root ball; plant in spring or fall

Soil

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

pH: 4.5-5.5

Amendments:

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

Growth Stages

Establishment

Year 1

Young plants settling in with slow initial growth, developing root system

Water regularly; apply 2-3 inches of pine mulch; avoid fertilizer year one; prune lightly to shape

Vegetative Growth

Years 2-3

Bushy spreading growth with wiry stems and narrow, elongated leaves; no flowers yet

Maintain consistent moisture; fertilize with acid-forming fertilizer (ammonium sulfate) in spring; remove flower buds first 2 years to encourage plant vigor

Flowering

3-4 weeks in spring (April-May depending on zone)

Small, bell-shaped white to pale pink flowers appear in spring clusters before leaf emergence; very ornamental

Minimal intervention; flowers are hardy to late frosts; thin crowded flower clusters if desired for larger berries

Fruiting & Ripening

6-8 weeks (June-July depending on zone)

Berries develop from green to pink to full blue color; Weymouth ripens early to mid-summer; berries are small (0.4-0.5 inches) but numerous

Maintain steady water supply during berry development; net against birds if desired; harvest when fully blue for best flavor

Dormancy & Fall

September-April

After berry harvest, foliage turns attractive red-bronze in fall; plants go fully dormant by late fall; stems remain visible through winter

No special care needed; cold dormancy is essential for next year's flowering; optionally prune in late winter/early spring before growth resumes

Companion Planting

Plan your garden →

Plant with:

Cranberry Lingonberry Lowbush blueberry (other varieties) Bearberry Heathers Sedges Labrador tea

Avoid planting near:

Rhododendrons (different water needs) Juniper (allelopathic tendencies) Plants preferring neutral-alkaline soil

Common Pests

Yellow sticky traps; remove infested berries; clean up fallen fruit; apply spinosad if severe
Pheromone traps; hand-pick infested berries; carbaryl or spinosad spray at bud break if needed
Remove and destroy infested canes below the entry hole; maintain plant health; prune out weak growth
Spray with water to dislodge; neem oil if population is high; ensure adequate humidity
Hand-pick beetles; encourage beneficial predators; spinosad spray if defoliation is severe

Uses

🍳

Fresh eating and preserves

Culinary

Weymouth berries are sweet and flavorful, perfect for fresh consumption, jams, jellies, pies, and baked goods. Early ripening makes them valuable for extending the blueberry season. [source]

💊

Antioxidant-rich superfood

Medicinal

Blueberries are rich in anthocyanins, pterostilbene, and other polyphenols with potential benefits for cardiovascular health, cognitive function, and anti-inflammatory effects. [source]

🍳

Processing and commercial use

Culinary

Weymouth's high yield and firm berries make it popular for commercial freezing, juice production, and dried blueberry products. [source]

🦋

Wildlife food source

Wildlife

Berries attract birds, deer, and small mammals; flowers provide early-season nectar for pollinators and beneficial insects. [source]

🏠

Ornamental landscape value

Household

Attractive spring flowers, edible summer berries, and brilliant fall foliage make Weymouth a multi-season garden asset with low maintenance. [source]

Harvest Tips

Pick berries when fully blue and slightly soft to gentle pressure (typically June-July). Weymouth ripens early, making it ideal for fresh eating or processing. Berries do not all ripen simultaneously, allowing for successive harvests over 3-4 weeks. For mechanical harvesting (commercial), berries abscise readily. Refrigerate fresh berries at 35-40°F; they keep 2-3 weeks.

Fun Facts

🌱 Lowbush blueberries like 'Weymouth' are the primary wild blueberry species commercially harvested in North America, particularly in Maine, where they're harvested with mechanical rakes across vast barrens managed through controlled burning.
🌱 Weymouth was developed in Maine specifically for cold hardiness and early ripening; it can produce berries even after temperatures drop to -40°F in winter, making it one of the hardiest cultivated blueberry varieties.
🌱 Lowbush blueberries have been consumed by Indigenous peoples of North America for thousands of years and were a staple food source; early European colonists learned to cultivate and value them alongside native cranberries.
