Harvest Tips
Pick berries when fully black and slightly soft, typically in early morning. Arapaho ripens earlier than most blackberries (late June in zone 6). Berries do not continue ripening after picking, so harvest only fully ripe fruit. For fresh market, pick into shallow containers to avoid crushing. Peak harvest window is 4-6 weeks; freeze surplus berries for year-round use.
Fun Facts
- 🌱 Arapaho was developed by the USDA Agricultural Research Service and released in 2004; it was one of the first thornless, upright blackberries suitable for home gardeners.
- 🌱 The thornless characteristic is a recessive genetic trait, making thornless blackberries more challenging to breed but highly valued for easier picking and safer handling.
- 🌱 Arapaho ripens 2-3 weeks earlier than traditional blackberry varieties like 'Navaho,' giving it a significant commercial advantage and allowing for extended fresh market seasons.
