Flowering
4-6 weeks in late April through MayFloricanes (second-year canes) produce white or pale pink flowers from leaf axils in late spring

Harvest Tips
Pick berries when fully black and slightly soft to touch, typically in June-July. Harvest every 2-3 days for peak ripeness. Berries do not ripen after picking, so wait for full maturity on the plant. Chester's thornless canes make harvesting much easier. Store unwashed berries in refrigerator for up to one week.
