Harden off and plant thyme

Thyme is a low-growing perennial herb with tiny, aromatic leaves and a warm, earthy flavor. It is one of the most versatile culinary and medicinal herbs.
Carson City, Nevada is in USDA Zone 7a. The average last spring frost is May 12 and the first fall frost is October 10, giving you a growing season of approximately 151 days.
At an elevation of 2,716 feet, Carson City receives approximately 8 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 98°F, so Thyme may need afternoon shade and extra watering during peak heat.

With low rainfall, drip irrigation is essential for growing Thyme successfully. Mulch heavily to conserve soil moisture.

Thyme 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.
