Growing Eggplant 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 eggplant outside around May — approximately 2 weeks after your last expected frost. Starting seeds indoors 8 weeks before the last frost date gives you a significant head start.
Eggplant thrives between 65°F and 90°F. It is frost-sensitive, meaning a single freeze at 32°F will damage or kill it — always wait until frost danger has fully passed. Expect 70–85 days from transplant to first harvest. Heat-loving. Similar to peppers.
