Lettuce is a fast-growing cool-season green available in leaf, romaine, butterhead, and crisphead types. It is the foundation of salads and one of the easiest crops to grow.
Acadia Parish, Louisiana is in USDA Zone 9a. The average last spring frost is February 12 and the first fall frost is December 6, giving you a growing season of approximately 297 days.
At an elevation of 259 feet, Acadia Parish receives approximately 61.4 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 103°F, so Lettuce may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring — great for early planting — but Lettuce will need more frequent watering and organic matter to retain nutrients. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Lettuce root diseases.

Lettuce Heat Requirements (GDD)
What are Growing Degree Days (GDD)?
Growing Degree Days measure the total warmth your plants receive during the growing season. Think of it as a "heat bank" — every day above 50°F deposits warmth that helps your plants grow.
Each plant needs a certain amount of accumulated heat to mature. If your county provides more GDD than the plant needs, it's a great fit. If it's close, you may want to choose faster-maturing varieties or start seeds indoors to get a head start.
