Growing Pumpkin in Chicago

Chicago's Zone 6a climate means a compressed but productive growing season roughly 190 days long. Lake Michigan moderates temperatures somewhat, but late spring frosts into April and early fall frosts in October keep the window tight. Succession planting and season extension tools like row covers make a big difference here.

In Chicago (last frost around April 22), aim to direct sow or transplant pumpkin outside around May — approximately 2 weeks after your last expected frost. Starting seeds indoors 3 weeks before the last frost date gives you a significant head start.

Pumpkin thrives between 65°F and 95°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 90–120 days from transplant to first harvest. Needs long warm season and lots of space.
