Establishment
12 monthsFirst year after planting; plant focuses on root development with minimal fruiting
Remove flower buds first year to encourage strong root system. Water consistently. Apply 2-3 inches of mulch. Protect from strong winds.
Vegetative Growth
24 monthsYears 2-3; plant develops branching structure and leaf canopy
Prune to open up center and remove crossing branches. Begin light fertilization with acid-forming fertilizer in spring. Maintain consistent watering.
Flowering
3-4 weeksSpring (April-May); small white or pale pink bell-shaped flower clusters appear
Do not prune during flowering. Ensure adequate bee activity for pollination. Avoid frost damage by monitoring weather. Cross-pollination with other highbush varieties increases yield.
Fruiting
6-8 weeksEarly to mid-summer (June-July); berries develop from green to blue over 3-4 weeks
Maintain steady water supply; inconsistent watering causes fruit cracking. Monitor for pests. Do not pick berries until fully blue and easy to detach.
Dormancy
4-5 monthsFall-winter; leaves turn red/burgundy, plant enters cold hardiness phase
Reduce watering in fall. Do not fertilize after August. Prune in late winter while dormant. Apply winter mulch in colder zones.

Harvest Tips
Berries ripen in early to mid-summer (June-July depending on region). Pick only fully blue berries; they continue to ripen on the plant but not after harvest. Ripe berries come off with gentle rolling between fingers. Harvest every 2-3 days for peak ripeness. Cool berries immediately after picking. Can be eaten fresh, frozen, or made into preserves. Yields typically 5-10 lbs per mature plant.
