When Is Blueberry Picking Season?

The season, region by region

Florida opens first (mid-March, via low-chill southern highbush varieties bred at the University of Florida), Georgia follows from late April, New Jersey's famous highbush season runs June–July, Michigan — the largest cultivated highbush producer — picks early July through late August, Oregon and Washington run June–August, and Maine's wild lowbush barrens finish the national season from late July into early September.

Typical windows, not promises — real dates shift with the weather (details below), and the farm's own field report always beats any calendar, including this one.

Varieties change the calendar

Southern highbush opens the season in FL/GA; rabbiteye carries Georgia into July; northern highbush rules NJ/MI/OR; and Maine's crop is wild lowbush — a different species picked on barrens, prime in August.

How to pick ripe blueberries

Ripe berries are uniformly deep blue all the way to the stem end — red or pink at the stem means underripe. The whitish waxy 'bloom' on the skin is a freshness sign, not a defect. A ripe berry separates with a gentle pull, and here's the pro move: berries need 3–5 days AFTER turning blue to reach peak sweetness, so pick the ones that have been blue a while (per UGA Extension C1294 and UF/IFAS).

How weather moves the season

Blueberry timing swings ±2–3 weeks in extreme years. The biology is citable: bushes stop growing below 38°F, ripening runs on temperatures between 46–68°F, cool nights under 50°F stall it, and days at 84°F+ shrink the fruit (UGA Extension). Bloom and young fruit are damaged below about 30°F — and frost-surviving flowers can still abort fruit later.

Before you go: u-pick ground rules

• Call ahead — always. Picking calendars drift one to two weeks on weather, and one busy Saturday can pick a field out and close it for days while the next block ripens. Check the farm's website or Facebook (many post field updates after weekends), or call the morning you plan to go.
• Containers and weigh-in. Farms usually provide flats or buckets. Bringing your own containers is often fine — but have them tare-weighed at the stand BEFORE you pick.
• Payment. Cash is the safe bet; card acceptance varies farm to farm. Most u-pick fruit sells by weight or by container — per-pound pricing is common partly because it removes any incentive to overfill.
• Wear and bring. Closed shoes or boots (fields are muddy and uneven), a sun hat, sunscreen, bug spray, and water. If anyone in the group has a bee allergy, bring the epi-pen.
• Follow the field rules. Pick only the rows the farm has opened — row rotation protects the blocks still ripening. Keep kids supervised, park where directed, and expect a no-dogs policy at many farms (it's a food-safety requirement, not unfriendliness).
• Tasting etiquette. A sample berry is usually fine; grazing your way down the row isn't — unpaid field snacking is straight income loss for the farm. When in doubt, taste after you pay.
