Growing Cauliflower in Nevada

Cauliflower in Nevada's Climate

Cauliflower is the most challenging brassica for subtropical zones. Temperature swings during heading cause buttoning. Only attempt during your most stable cool-weather window (November-January). Consider starting with broccoli instead — it's more forgiving in inconsistent warm-zone conditions.

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 cauliflower — adjust your planting dates to match your specific region.

Growing Tips

Blanch white varieties by tying outer leaves over the head when it reaches 2 inches. Temperature swings cause buttoning.

Companion Planting

Plant cauliflower alongside these companions for better growth:

Beets Celery Onions

Keep cauliflower away from:

Strawberries Tomatoes
