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.

Washington Parish, Louisiana is in USDA Zone 8b. The average last spring frost is March 11 and the first fall frost is November 22, giving you a growing season of approximately 256 days.

At an elevation of 439 feet, Washington Parish receives approximately 56.4 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 93°F, providing good warmth for Honeydew during the growing season.

Honeydew 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.

Honeydew needs ~1,876 GDD — county provides 5,056 GDD Excellent fit
