Harvest Tips
Berries ripen from late August through September. Pick berries when fully red and firm, gently rolling them into a hand or using a berry rake. Harvest early morning when berries are cool. For best flavor, allow berries to fully darken on the plant. Berries store well in the refrigerator for several weeks or can be frozen for long-term storage.
