The Short Answer

Pumpkins are frost-sensitive and need warm soil and air temperatures to thrive. Start seeds indoors 3 weeks before your last frost date, then transplant outside 2 weeks after your last frost when soil temperatures reach at least 65°F. You can also direct sow seeds 2 weeks after your last frost. Enter your zip code on our homepage tool for exact dates.

How to Grow Pumpkins

Pumpkins are a space-hungry, long-season crop that rewards patience. Vines can spread 15-20 feet, so plan accordingly or train them along a fence. For the biggest pumpkins, allow only one fruit per vine. For Jack-o-lantern pumpkins, 2-3 fruits per vine is fine. The stem is your ripeness indicator: when it turns corky and brown, and the skin resists your thumbnail, it's ready. Cure in the sun for 7-10 days after harvest to harden the skin for storage. Never carry a pumpkin by its stem — the weight will snap it off, creating an entry point for rot.

Starting Seeds Indoors

Begin pumpkins seeds indoors 3 weeks before your average last frost date. Seeds need soil temperatures of at least 65°F to germinate, which typically takes 5-10 days. Provide 12 hours of light per day using a south-facing window or grow lights.

Transplanting

Move seedlings outside 2 weeks after your last frost date, once soil temperatures reach 65°F. Harden off seedlings for 5 days before transplanting by gradually exposing them to outdoor conditions.

Direct Sowing

Pumpkins can be direct sown 2 weeks after your last frost date. Plant seeds 1" deep, spaced 60" apart.

Growing Tips

Count backwards from when you want ripe pumpkins (usually October). They need 90-120 days, so mid-June to early July is often ideal.
