Growing Dill 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), dill can go out around April — approximately 4 weeks before the last expected frost, making it an early-season opportunity.

Dill thrives between 50°F and 75°F. It tolerates temperatures as low as 35°F, making it a candidate for early spring planting before the last frost date. Expect 40–60 days from transplant to first harvest. Direct sow preferred. Don't like root disturbance.
