How to grow pumpkins in Nebraska, step by step
- Start seeds indoors (Apr 2 – Apr 16). Sow seeds 1 inch deep in seed-starting mix under bright light. They take 5-10 days to sprout, fastest in soil around 85°F. Harden seedlings off for a week before they go outside.
- Prepare the bed. They need at least six to eight hours of direct sun a day and loose soil at least 18 inches deep, with a pH between 5.5 and 7.5. Dig in compost before planting.
- Plant out (Apr 30 – May 17). Space plants about 48 inches apart in rows 96 inches apart. It is killed by frost, so nothing goes outside until the danger has passed.
- Water and feed. Give it steady, even moisture, about an inch of water a week from rain or the hose.
- Watch for pests and problems. Pests: squash vine borer, squash bug, striped cucumber beetle. Diseases and disorders: powdery mildew, bacterial wilt.
- Harvest (from about Aug 5 – Sep 4). Pumpkin takes 90-120 days to reach harvest. For Halloween pumpkins in the north, count back 100-120 days from 31 Oct and start indoors. Mini varieties can climb a strong trellis.

Planting pumpkins in Nebraska for Halloween
Spring dates above suit a long season. If you want fruit ready for Halloween, count back from Nebraska's average first fall frost (October 5), which comes before Halloween. Pumpkin takes 90–120 days from sowing to a mature fruit, so these are the latest sowing dates. Sow earlier for a margin, but not too early: the University of Arkansas Extension warns that pumpkins planted too early may rot before Halloween.
| Days to maturity | Latest sowing for Halloween | Typical for |
|---|---|---|
| 120 days | June 7 | slowest types (giants) |
| 100 days | June 27 | jack-o'-lantern and pie types (University of Arkansas variety table) |
| 90 days | July 7 | quickest types |
See the full growing guide for pumpkin. Days to maturity vary by variety, so check the seed packet.
