Harvest Tips
Harvest berries when fully blue and slightly soft to touch, typically in early to mid-summer (May-June in warm regions). Pick every 3-4 days during peak season. Berries do not ripen after picking, so only harvest fully colored fruit. Store at 32-40°F for up to 2 weeks; for best flavor, eat fresh within days of harvest.
Fun Facts
- 🌱 Stella Blue was specifically bred for low-chill environments, requiring only 150-300 chill hours compared to 600+ for traditional highbush varieties, making it perfect for USDA zones 8-10.
- 🌱 Blueberries can live and produce for 40+ years with proper care, making them a long-term investment that actually improves with age.
- 🌱 The white waxy coating on ripe blueberries, called 'bloom,' is a natural protective layer that helps preserve freshness and indicates peak ripeness—berries without this coating were picked too early.
