Sweet marjoram is a tender perennial herb with a delicate, sweet oregano-like flavor. It is a cornerstone of Mediterranean cooking and pairs well with meats and vegetables.

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.

At an elevation of 5,832 feet, Mineral County receives approximately 14.8 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 100°F, so Marjoram may need afternoon shade and extra watering during peak heat.

Marjoram 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.

Marjoram needs ~1,875 GDD — county provides 4,125 GDD Excellent fit
