Growing Cilantro in Nevada
Cilantro in Nevada's Climate
Sow cilantro from November through January — the window is very brief. Use slow-bolt varieties (Santo, Calypso) exclusively. Vietnamese cilantro is the essential warm-season companion crop — it provides cilantro flavor year-round in conditions where true cilantro cannot survive.
Soil Considerations for Nevada
Desert soils — alkaline, low organic matter. Extremely dry. Heavy amendment essential. Irrigation required.
Nevada Climate & Growing Season
Arid climate. Extreme heat in summer (Las Vegas). Short season at altitude. Very low humidity. Water conservation critical.
Growing season length varies across Nevada: Northern Nevada (Reno) (6b, 7a) has a last frost around May 1 - May 20, while Mountain Nevada (4a, 4b, 5a, 5b) sees frost end around May 25 - Jun 15. This difference matters for cilantro — adjust your planting dates to match your specific region.
