Minnesota summer raspberry and blueberry growers report fields full of blossoms and expect to open for pick-your-own and pre-picked berries the first two weeks of July.

Raspberry and blueberry seasons start towards the end of strawberry season and usually last at least three weeks, depending on the variety and weather conditions.

As with strawberries, seasonal availability begins in southern Minnesota and travels northward. Mild temperatures in the 70s and 80s extend the seasons and allow berries to ripen at a steady pace, while excessive heat can cause berries to ripen more quickly and shorten the seasons.
