When to Plant Radishes in Nevada

The fastest vegetable in the garden — some varieties are ready in just 25 days. Perfect for impatient gardeners and kids.

The Short Answer

In Nevada, soil conditions are an important factor for radishes. Desert soils — alkaline, low organic matter. Extremely dry. Heavy amendment essential. Irrigation required. Direct sow 4 weeks before your last frost date. Radishes can also be planted in fall, 6 weeks before your first frost.

Growing Radishes in Nevada

Radishes in Nevada's Climate

Sow radishes from November through January only. The window is brief. The good news: they're so fast-maturing (22-30 days) that you can get 3-4 succession plantings even in the shortest cool window.

Soil Considerations for Nevada

Desert soils — alkaline, low organic matter. Extremely dry. Heavy amendment essential. Irrigation required. Loose, well-drained soil is especially important for radishes since the edible portion grows underground. If your soil is heavy clay, consider raised beds.

Nevada Climate & Growing Season

Arid climate. Extreme heat in summer (Las Vegas). Short season at altitude. Very low humidity. Water conservation critical. Radishes 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 radishes — but radishes handle frost well, so the timing difference is less critical.

Growing Tips

Don't let them stay in the ground too long — they get pithy and hot. Succession plant every 2 weeks for continuous harvest.

Companion Planting

Plant radishes alongside these companions for better growth:

Peas Lettuce Carrots Spinach

The Bottom Line

Radishes can be grown successfully across Nevada, but your exact planting dates depend on which region you're in. Northern Nevada (Reno) gardeners should plan around a May 1 - May 20 last frost, while those in Mountain Nevada can typically plant later.
