Harvest Tips
Harvest when cherries are fully dark red to nearly black and slightly soft to the touch, typically mid-June to early July. Pick with stems attached for fresh eating to extend shelf life. For processing into preserves or pies, cherries can be picked without stems. Use a gentle hand to avoid bruising. Refrigerate immediately after picking; they will keep 1-2 weeks at 32°F.
