When to Plant Honeydew in St. James Parish, LA

Honeydew melons have smooth, pale green rinds and sweet, light green flesh. They require a long, warm growing season and are slightly more heat-tolerant than cantaloupe.

St. James Parish, Louisiana is in USDA Zone 9a. The average last spring frost is February 13 and the first fall frost is December 6, giving you a growing season of approximately 296 days.

At an elevation of 471 feet, St. James Parish receives approximately 52 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 97ยฐF, so Honeydew may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring โ€” great for early planting โ€” but Honeydew will need more frequent watering and organic matter to retain nutrients. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Honeydew root diseases.
