When to Plant Pole Beans in Lafourche Parish, LA

Pole beans are climbing varieties of green beans that produce over a much longer season than bush types. They require trellising but yield more per square foot.

Lafourche Parish, Louisiana is in USDA Zone 9a. The average last spring frost is January 27 and the first fall frost is December 18, giving you a growing season of approximately 325 days.

At an elevation of 306 feet, Lafourche Parish receives approximately 54 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 97ยฐF, so Pole Beans may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring โ€” great for early planting โ€” but Pole Beans will need more frequent watering and organic matter to retain nutrients. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Pole Beans root diseases.
