Harvest Tips
Berries ripen over several weeks in early to mid-summer (June-July depending on location). Harvest when fully dark purple-black and soft to touch. Berries do not ripen uniformly, so multiple harvests may be needed. Shake branches gently over a cloth to collect berries, or handpick. Ripe berries are sweet with mild nutty flavor. Store in refrigerator for up to 2 weeks, or freeze for extended storage.
