Remove most flowers first 2 years to encourage root establishment. Water deeply and regularly. Apply 3-4 inches of mulch.
Vegetative Growth
1-2 yearsShrub develops strong branching structure with dark green, elongated leaves; no or minimal flowering
Prune to shape and promote branching. Fertilize with blueberry-specific fertilizer in spring. Maintain consistent moisture.
Flowering
2-4 weeks (typically March-April)Small, delicate white or pale pink flowers appear in clusters along branches in spring
Protect flowers from late frosts if possible. Allow pollination by native bees. Do not fertilize during flowering to avoid promoting excessive vegetative growth.
Fruiting
6-8 weeks (June-July in zone 8)Flowers develop into small green berries that gradually enlarge, turning blue-black when ripe
Thin berries if overcrowded for larger individual fruits. Maintain consistent watering. Do not allow drought stress. Watch for bird predation.
Harvest & Post-Harvest
2-3 weeks harvest windowFully ripe berries are ready to pick; plant begins preparing for dormancy in fall with leaf color change

Harvest Tips
Pick berries when fully dark blue—they do not ripen further after picking. Gently roll berries into your palm; ripe berries detach easily. Harvest every 3-4 days during peak season (late June through July in zone 8). For best flavor, pick in early morning after dew dries. AU-Choctaw berries store well in refrigerator for 2-3 weeks or can be frozen.
Fun Facts
- 🌱 AU-Choctaw was developed by Auburn University's breeding program and is named after a Native American nation; it was released in 1991 and has become one of the most reliable rabbiteye blueberries for home gardeners.
- 🌱 Rabbiteye blueberries like AU-Choctaw are more heat and drought-tolerant than Northern highbush blueberries, making them ideal for the Deep South and warm climates.
- 🌱 Blueberries require cross-pollination with another compatible blueberry variety to produce a full crop; while AU-Choctaw can partially self-pollinate, yields improve significantly when planted with another rabbiteye variety like Premier or Brightwell.
