When to plant pumpkins for Halloween: soil and state dates

Pumpkins are frost-tender, and most home growers plant them with one date in mind: the end of October. Sow too early and the fruit can soften before then.

Each line names the Extension service it comes from and links to their page. Vine size changes spacing a lot, so each service's figures are listed.

When to plant

  • Illinois Extension says to wait until frost danger has passed and the soil is well warmed; for Halloween, sow from late May in the north to early July in the far south, since early fruit may rot first. Pumpkin (Home Vegetable Gardening) · checked 2026-09-27
  • Clemson Cooperative Extension says most varieties need to be planted by early July to be ripe for Halloween; pumpkins take roughly 70 to 120 days to mature. Pumpkins & Winter Squash (HGIC fact sheet) · checked 2026-09-27

Harvest

  • Clemson Cooperative Extension says only fully mature fruit stores well; cut rather than tear it from the vine and keep a generous stem. Pumpkins & Winter Squash (HGIC fact sheet) · checked 2026-09-27
