Harvest Tips
Berries ripen sequentially over 3-4 weeks in June-July (timing varies by zone). Harvest ripe berries by gently shaking branches over a cloth or picking by hand when berries are dark purple-black and soft. Ripe berries fall easily from the tree. Check tree every 2-3 days during harvest season. Eat fresh, refrigerate, or freeze immediately as berries do not store long at room temperature.
