Growing Pumpkin in Aurora
Aurora sits at over 5,400 feet in Zone 5b, sharing Denver's challenging high-altitude gardening environment. The growing season is compact — around 150 days — with late spring frosts and early fall cold snaps. High-UV solar radiation speeds plant development but also increases water evaporation from soil. Raised beds, drip irrigation, and careful variety selection for short seasons are keys to success here.
In Aurora (last frost around May 7), 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.
