According to the Minnesota Department of Natural Resources, growers across the state have reported fields full of blossoms and are expecting to be open for pick-your-own and pre-picked blueberries and raspberries the first two weeks of July.

Blueberry and raspberry season starts towards the end of strawberry season. As with strawberries, seasonal availability begins in southern Minnesota and moves northward. Blueberry season usually lasts at least three full weeks depending on the variety and weather conditions. Mild temperatures in the 70s and 80s extend the season and allow berries to ripen at a steady pace, while excessive heat can cause berries to ripen more quickly and shorten the season.

Bill Hein of Straight River Farm in Faribault recommends using color to gauge ripeness.

“Color change typically signals that it is time to harvest, so look for a deep color,” said Hein. “Mature berries will detach easily. If you have to tug, the berry’s not ripe yet.”
