Establishment
Year 1-2Young plant develops root system and vegetative growth. Foliage is light green and tender.
Remove flowers in first 2 years to encourage root and branch development. Water regularly and mulch heavily. Avoid fertilizer competition.
Vegetative Growth
Year 2-3Plant grows upright branches with alternate leaves. New shoots emerge throughout the growing season.
Prune to maintain open, vase-like structure. Remove crossing or weak branches. Thin shoots to promote larger berry production.
Flowering
3-4 weeks in springDelicate, bell-shaped white to pale pink flowers appear in spring clusters along stems.
Flowers are self-fertile but benefit from cross-pollination with another highbush variety. Protect from late frosts that damage flowers. Don't fertilize during flowering.
Fruiting & Berry Development
6-8 weeksFlowers set fruit; small green berries develop and gradually enlarge. Berries transition from green to red to dark blue.
Thin fruit clusters if berries are small; remove about 20-30% of developing fruit for larger berries. Maintain consistent moisture. Monitor for pests and diseases.
Harvest & Dormancy
3-4 months harvest, then dormancyRipe dark blue berries are ready to pick. Foliage turns brilliant red and burgundy in fall. Plant goes dormant in winter.
Pick berries when fully blue (they don't ripen after harvest). Prune in late winter during dormancy. Clean up fallen leaves to reduce disease pressure.

Harvest Tips
Pick berries when fully dark blue; they develop full sweetness and will not continue to ripen after harvest. Gently twist or roll berries in your palm—ripe berries detach easily. Harvest in morning after dew dries for best flavor. A mature plant (4+ years) yields 10-15 pounds per year. Berries continue ripening over 2-3 weeks, allowing successive harvests.
