What sets the timing for pumpkins

When to plant pumpkins comes down to one date: your last spring frost. Pumpkins is a tender crop, so it goes in about 2 weeks after your last spring frost. In a mid climate (zone 5) that's around Apr 29.

Give it a head start: sow seeds indoors about 2 weeks before your last spring frost (around Apr 1 in zone 5), then move seedlings out once conditions are right. From there it's roughly 110 days to harvest.

Because that anchor date moves with climate, plant-out for pumpkins ranges from about Mar 24 in warm zone 3 to May 29 in cold zone 7. Enter your ZIP in the calculator for the exact dates in your zone.
