Growing Spinach in Nevada
Spinach in Nevada's Climate
Spinach requires the narrowest window of any green in subtropical zones. Sow from November through January only. Once temperatures exceed 70°F consistently, spinach bolts within days. Vietnamese cilantro and Malabar spinach are warm-weather alternatives that fill the same role in the kitchen.
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. Spinach can handle frost well, which is an advantage in Nevada's climate. You can push planting dates earlier in spring and extend into fall.
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 spinach — adjust your planting dates to match your specific region.
Growing Tips
Direct sow as soon as soil can be worked in spring. For fall, plant 6-8 weeks before first frost.
Companion Planting
