Growing Blueberry in Milwaukee

Milwaukee's Zone 5b climate on Lake Michigan's western shore means a short but intense growing season of about 155 days. The lake moderates spring and fall temperatures, but last frosts can stretch into early May. Warm-season crops need to be started indoors in late March and transplanted only after the frost risk passes. The reward is productive summers with excellent tomato and squash harvests.

In Milwaukee (last frost around May 5), aim to direct sow or transplant blueberry outside around May — approximately 2 weeks after your last expected frost.

Blueberry thrives between 60°F and 85°F. It tolerates temperatures as low as 20°F, making it a candidate for early spring planting before the last frost date. Expect 365–730 days from transplant to first harvest. Needs acidic soil (pH 4.5–5.5). Plant 2+ varieties for pollination. Perennial — produces for decades.
