Mineral County, Nevada is in USDA Zone 7a. The average last spring frost is April 28 and the first fall frost is October 10, giving you a growing season of approximately 165 days.

Tomatoes 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.

Tomatoes needs ~1,812 GDD — county provides 4,125 GDD Excellent fit
