Establishment
Year 1Young transplant developing root system and basic branch structure
Plant in acidic soil with peat moss amendment. Keep consistently moist. Remove flowers first year to encourage root and shoot development. Mulch with 2-3 inches of pine bark.
Vegetative Growth
Year 2-3Plant develops dense branching and increases in height; limited flowering
Allow some flowering in year 2-3. Prune out weak or crossing branches. Maintain acidic pH. Feed with acid-forming fertilizer (ammonium sulfate). Continue heavy mulching.
Flowering
3-4 weeks (spring)Abundant pink-white clusters of small bell-shaped flowers appear in spring
Flowers are self-fertile and attract pollinators. Do not apply pesticides during bloom. Ensure consistent water during flowering to prevent flower drop.
Fruiting
6-8 weeks (late spring to summer)Small green berries develop and gradually ripen to blue, becoming sweeter over 3-4 weeks
Thin fruit if extremely heavy crop to increase berry size. Maintain consistent water. Continue fertilizing with potassium-rich formula. Protect from birds with netting if desired.
Harvest & Dormancy
Summer through winterBerries ripen fully; foliage turns red in fall before leaves drop
Harvest ripe berries every 2-3 days. Allow plant to go dormant in winter. Prune in late winter to remove dead wood and maintain shape. Reduce water in fall.

Harvest Tips
Berries are ready when fully blue (3-4 days after color appears) and slightly soft. Harvest every 2-3 days at peak ripeness for sweetest flavor. Gently roll ripe berries into your palm—they should fall off easily when fully ripe. Best picked in early morning. Refrigerate immediately; berries keep 2-3 weeks in fridge.
