Harvest Tips
Pick berries only when completely black and slightly soft to the touch; they will not ripen further after harvest. Gently twist and pull or use scissors to avoid damaging branches. Wear gloves if concerned about staining. Harvest every 2-3 days during peak season to encourage continued flowering. Taste before consuming—fully ripe berries are sweet-tart; underripe berries taste slightly bitter.
