Establishment (Year 1)
Year 1Young plant focuses on root development with minimal flowering; shoots are tender and light green
Remove all flowers first year to encourage root establishment. Water consistently 2-3 times weekly. Mulch heavily with 3-4 inches of pine bark. Avoid fertilizer or use light application of acid-forming fertilizer.
Vegetative Growth (Years 2-3)
Years 2-3Plant develops strong branching structure with increasingly vigorous shoots; leaves are medium green and healthy
Prune to develop open vase-shaped form; remove weak or crossing branches. Apply balanced or slightly higher nitrogen fertilizer in spring. Continue consistent watering and mulching.
Flowering (April-May)
3-4 weeksDense clusters of small, white bell-shaped flowers appear on branch tips and along stems
Maintain consistent moisture during flowering to support fruit set. Do not prune during flowering. Apply potassium-rich fertilizer if flower production is light. Monitor for frost damage in late freeze events.
Fruiting & Ripening (June-July)
6-8 weeksSmall green berries develop and gradually enlarge, changing from green to light blue to dark blue; berries are firm when ripe
Maintain consistent watering to prevent cracking. Berries ripen progressively over 2-3 weeks. Protect from birds with netting if desired. Reduce nitrogen fertilizer to avoid excessive vegetative growth.
Dormancy (November-February)
3-4 monthsLeaves turn yellow, red, or burgundy and drop; plant appears bare with woody stems visible
Reduce watering significantly. Prune in late winter (February-March) before new growth emerges. Remove dead, diseased, or crossing wood. Thin to maintain open center for air circulation.

Harvest Tips
Pick berries when fully dark blue and soft; they do not ripen after harvest. Berries are ready 7-10 days after turning blue. Pick every 3-4 days during peak season as berries ripen progressively. Gently roll berries in palm to harvest—ripe berries detach easily. Harvest in early morning for best flavor and shelf life. Climax typically produces 8-15 pounds per mature plant by year 4-5.
Fun Facts
- 🌱 Rabbiteye blueberries get their name from the distinctive reddish appearance of the berry scar at the end of the fruit, which resembles a rabbit's eye.
- 🌱 Climax is notably self-fertile (unlike some blueberry varieties) but produces significantly higher yields when cross-pollinated with other rabbiteye cultivars like Tifblue or Powderblue.
- 🌱 Rabbiteye blueberries require fewer chill hours than highbush varieties, making them better adapted to warm southern climates where traditional highbush blueberries struggle.
