When to Plant Rosemary in Nye County, NV

Rosemary is an aromatic evergreen shrub with needle-like leaves and a piney, citrus flavor. It is a Mediterranean herb that thrives in warm, dry conditions.

Nye County, Nevada is in USDA Zone 7a. The average last spring frost is May 6 and the first fall frost is October 14, giving you a growing season of approximately 161 days.

At an elevation of 3,654 feet, Nye County receives approximately 9.8 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 97ยฐF, so Rosemary may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring โ€” great for early planting โ€” but Rosemary will need more frequent watering and organic matter to retain nutrients. With low rainfall, drip irrigation is essential for growing Rosemary successfully. Mulch heavily to conserve soil moisture.

Rosemary 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.

Rosemary needs ~2,958 GDD — county provides 3,662 GDD Good fit
