When to Plant Pumpkins in Mississippi
Published: April 24, 2026
Mississippi gardeners in Zone 8a enjoy an extended 41-week growing season for pumpkin. Warm-climate gardeners can grow two pumpkin crops — a spring planting and a fall planting — with summer heat as the main challenge to work around. This guide gives exact dates for Mississippi based on your local frost calendar.
Pumpkin Planting Dates for Mississippi
| Start seeds indoors | January 25–February 1 |
| Last frost (average) | February 15 |
| Transplant outdoors | February 22–March 4 |
| Direct sow outdoors | February 22–March 4 |
| Expect first harvest | May 8 – June 2 |
| First fall frost (average) | December 1 |
Dates above assume Zone 8a, the most common zone in Mississippi. Gardeners in cooler Jackson (Zone 8a) plant 1–2 weeks later; warmer Gulfport (Zone 8b) can plant 1–2 weeks earlier.
⚠ Count back 75–100 days from desired harvest date. For Halloween harvest, plant late June to mid-July. Plant 1–2 weeks after last frost.
Growing Pumpkins in Mississippi's Climate
Mississippi's warm Zone 8a climate gives pumpkin more than enough heat — in fact, peak summer heat (95°F+) can shut down fruit set entirely. The solution most Mississippi gardeners use is a two-season approach: a spring crop planted early, a harvest break during peak summer, and a fall crop planted July through August for October and November harvest.
Variety selection matters more in warm climates than most gardeners realize. Choose heat-tolerant varieties bred for Mississippi-like conditions — local extension offices and nurseries stock these specifically. Afternoon shade cloth during July and August can be the difference between a working fall crop and total flower drop.
Common pumpkin pests to watch for in Mississippi include Squash Vine Borer and Squash Bug. The first line of defense is companion planting: Corn and Bush Bean planted nearby discourage several of these pests by confusing host-plant identification or repelling adults before they can lay eggs. Weekly garden walks in the early morning catch problems when they're still manageable.

- •Plant on hills or mounds to warm soil and improve drainage; two plants per hill is plenty.
- •Mississippi's summer heat shuts down pumpkin flowering at 95°F+. Choose heat-tolerant varieties and use shade cloth from mid-June through August to preserve fruit set.
- •Rotate pumpkins away from squash, cucumber, and melon beds on a 3-year cycle to break disease cycles.
