When to Plant Melon in Morris County, TX

Melons are warm-season vine crops that produce sweet, juicy fruits in many varieties including muskmelon and honeydew. They need a long, hot growing season.

Morris County, Texas is in USDA Zone 8a. The average last spring frost is March 12 and the first fall frost is November 11, giving you a growing season of approximately 244 days.

At an elevation of 185 feet, Morris County receives approximately 69.9 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 96ยฐF, so Melon may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring โ€” great for early planting โ€” but Melon will need more frequent watering and organic matter to retain nutrients. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Melon root diseases.

Melon 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" โ€” every day above 50ยฐF 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.

Melon needs ~1,870 GDD — county provides 5,368 GDD Excellent fit
