When to Plant Pumpkins in Louisiana
Published: April 24, 2026
Louisiana gardeners in Zone 8b enjoy an extended 45-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 Louisiana based on your local frost calendar.
Pumpkin Planting Dates for Louisiana
| Start seeds indoors | January 11–18 |
| Last frost (average) | February 1 |
| Transplant outdoors | February 8–18 |
| Direct sow outdoors | February 8–18 |
| Expect first harvest | April 24 – May 19 |
| First fall frost (average) | December 15 |
Dates above assume Zone 8b, the most common zone in Louisiana. Gardeners in cooler New Orleans (Zone 8b) plant 1–2 weeks later; warmer Shreveport (Zone 8a) 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 Louisiana's Climate
Louisiana's warm Zone 8b climate gives pumpkin more than enough heat — in fact, peak summer heat (95°F+) can shut down fruit set entirely. The solution most Louisiana 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 Louisiana-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 Louisiana 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.

Pumpkin Growing Tips for Louisiana Gardeners
- •For Halloween pumpkins, count back 75–100 days from October 31 — plant between late June and mid-July in most climates.
- •Plant on hills or mounds to warm soil and improve drainage; two plants per hill is plenty.
- •Louisiana'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.
Companion Planting for Pumpkins in Louisiana
In Louisiana's warm climate, planting pumpkin with Corn and Bush Bean helps deter pests and improve soil. Avoid planting near Potato and Summer Squash, which inhibit pumpkin growth through root chemistry or shared pest pressure. See the full pumpkin companion planting guide for the complete list.
