Harvest Tips
Berries ripen progressively from early summer (June) through fall (September-October); pick when fully dark and soft, typically every few days as new berries mature. Berries do not all ripen at once—the 'everbearing' trait means continuous flowering and fruiting. Harvest in early morning or evening when cooler. Spread cloth under tree and gently shake branches for easier collection. Best flavor when fully ripe and fully dark.
