SOUTH BEND, Ind. -- Blueberry Festival is the annual sign that summer is coming to an end; but this year is one of the best, weather wise, Marshall County has seen in a while for it. The clear skies are putting the “blue” in blueberry.
The first day of the festival will welcome guests beginning at noon with temperatures starting in the 60s. Highs will struggle to break 70 degrees today, with highs only peaking in the upper 60s. Guests planning their visits in the evening, a jacket is recommended as temperatures will fall to the low 60s and upper 50s. The rest of the weekend looks just as great, with highs increasing to the 70s through Memorial Day. From pageants and parades to fireworks and drone shows—there is something for everyone—day or night.
There can't be Blueberry Fest without blueberries, and the weather plays a big part in blueberry harvest. Like all crops, blueberries rely on specific weather conditions for a successful harvest.
Highbush blueberry varieties require a period of "chilling hours". A cold, but not harsh, winter temperatures between 32°–45°F. This supports spring flower development.
Warm, humid and sunny summers are also needed in fruit development— with blueberry plants often needing 6-8 hours of sunlight. Consistent moisture is also necessary; and despite some summer drought, irrigation has helped maintain crop health.
According to the North American Blueberry Council, the Michiana region is seeing peak harvest volumes, though berry sizes are slightly smaller due to this summer’s dry spells. Still, the outlook remains positive.
Come see for yourself! The Plymouth Blueberry Fest will be in town, with all thing's blueberry, through Memorial Day Weekend.
