When are blueberries ready to pick?

Blueberries are typically ready to pick when they have turned a deep blue color, are plump, and easily come off the stem with a gentle tug. This usually occurs in mid to late summer, depending on the variety and local climate conditions. It's important to harvest them when they are fully ripe, as unripe berries will not continue to ripen after being picked. Checking the bushes regularly during the harvest season will help determine the best time to gather them.
