Harvest blueberries when the fruit are fully ripe. The best indicators of ripeness are color, flavor, and picking ease. Fully ripe blueberries are uniformly blue in color, have a good flavor, and separate easily from the plant. (Do not harvest blueberries on color alone as the berry is often blue for some time before being fully ripe.) After harvesting, immediately store blueberries in the refrigerator. Maximum storage life is 7 to 10 days.
