Establishment
Year 1Young shrub focuses on root development with minimal flowering. Plant appears dormant in winter with bare branches.
Water deeply and regularly. Remove flower buds first year to encourage root establishment. Apply 2-3 inches of mulch around base.
Vegetative Growth
Years 1-2Shrub develops woody stems and foliage. Small white bell-shaped flowers appear in clusters in spring.
Prune lightly to shape; remove any weak or crossing canes. Allow some flowers to develop fruit in year 2.
Flowering
3-4 weeks in springAbundant clusters of delicate white tubular flowers appear from mid-spring, attracting pollinators. Flowers are self-fertile but cross-pollination improves yields.
Ensure good bee access. Do not use pesticides during bloom. Thin flower clusters if desired to increase berry size.
Fruiting & Development
6-8 weeks mid-summerSmall green berries develop from fertilized flowers, gradually enlarging and changing color from green to light blue to deep blue as they mature. Berries ripen unevenly over 2-3 weeks.
Maintain consistent watering during fruit development. Thin berries if extremely abundant to promote larger fruit. Protect from birds with netting if desired.
Harvest & Dormancy
3-4 weeks harvest; 5 months dormancyFully ripe berries are deep blue with a slight waxy bloom. Foliage turns red and yellow in fall. Plant enters winter dormancy with bare branches; requires adequate cold hours (800-1200 hours below 45°F).
Harvest ripe berries by hand, rolling gently into palm. Do not harvest unripe berries—they do not ripen after picking. Prune dormant canes in late winter before bud break.

Harvest Tips
Berries ripen over several weeks mid-summer (typically June-July in northern zones, July-August in southern zones). Pick only fully ripe, deep blue berries—they do not ripen after harvest. Gently roll ripe berries into your palm; they should come off easily when ready. Harvest every 2-3 days as berries mature. Refrigerate immediately to preserve quality; fresh berries keep 1-2 weeks.
Fun Facts
- 🌱 Centurion blueberry was developed to produce exceptionally large berries (up to 1 inch diameter) while maintaining the sweet flavor of smaller highbush varieties, making it popular for commercial growers and home gardeners alike.
- 🌱 Blueberries require cross-pollination with a different highbush cultivar (such as Duke, Berkeley, or Elliott) to achieve maximum fruit set and berry size, though they can set some fruit with self-pollination.
- 🌱 Blueberries have been part of North American indigenous diets for thousands of years and were valued both as food and medicine; modern horticulture has expanded their cultivation far beyond their native range in eastern North America.
