When to Plant Corn in Eureka County, NV

Corn is a warm-season grass grown for its sweet ears, which are best eaten soon after harvest. It is wind-pollinated and must be planted in blocks for good kernel fill.

Eureka County, Nevada is in USDA Zone 5b. The average last spring frost is May 30 and the first fall frost is September 20, giving you a growing season of approximately 113 days.

At an elevation of 8,408 feet, Eureka County receives approximately 14.7 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 92ยฐF, providing good warmth for Corn during the growing season. Sandy soil warms quickly in spring โ€” great for early planting โ€” but Corn will need more frequent watering and organic matter to retain nutrients. With low rainfall, drip irrigation is essential for growing Corn successfully. Mulch heavily to conserve soil moisture.

Corn 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.

Corn needs ~1,520 GDD — county provides 2,147 GDD Excellent fit
