Harvest Tips
Berries ripen over several weeks from June-July. Harvest only fully dark blue berries with waxy coating; they do not continue ripening after picking. Pick every 3-4 days when in full production. Gently roll berries into palm—ripe berries detach easily. Refrigerate promptly; will keep 3-4 weeks in fridge or freeze for long-term storage.
Fun Facts
- 🌱 Tifblue was developed at the University of Georgia in the 1970s specifically for southern growing conditions and is the most widely planted rabbiteye blueberry in the southeastern United States.
- 🌱 Tifblue is a rabbiteye blueberry variety (Vaccinium ashei), not a highbush variety; rabbiteye blueberries are more heat and disease-resistant than traditional highbush varieties and produce smaller plants that are better for small spaces.
- 🌱 A single mature Tifblue blueberry bush can produce 15-30 pounds of berries per year under optimal conditions, making it one of the most productive home garden fruits.
