When to Plant Kale in Nevada
Published: April 24, 2026
Nevada gardeners in Zone 9a enjoy an extended 46-week growing season for kale. Cool-season crops like kale do best in fall, winter, and early spring in Nevada — the hot summers bolt these plants before they can be harvested. This guide gives exact dates for Nevada based on your local frost calendar.
Kale Planting Dates for Nevada
| Start seeds indoors | December 26–January 2 |
| Last frost (average) | January 30 |
| Transplant outdoors | January 2–12 |
| Direct sow outdoors | January 2–12 |
| Expect first harvest | February 26 – March 18 |
| Fall crop start | October 20–30 |
| Fall harvest | December 14 |
| First fall frost (average) | December 15 |
Dates above assume Zone 9a, the most common zone in Nevada. Gardeners in cooler Reno (Zone 6a) plant 1–2 weeks later; warmer Las Vegas (Zone 9a) can plant 1–2 weeks earlier.
⚠ Plant kale 3–5 weeks before last frost for spring. Best planted in late summer (6–8 weeks before first fall frost) for fall/winter harvest. Frost sweetens the flavor.
Growing Kale in Nevada's Climate
Nevada's warm Zone 9a climate makes kale a fall, winter, and early spring crop rather than a summer one. The cool-season window runs roughly October through April in Nevada — plant outside this window and the kale will bolt (send up a flower stalk and turn bitter) before it produces a harvestable crop.
Succession planting stretches the kale harvest window. Sow small amounts every two weeks from October through February — you will have staggered harvests rather than a single wave to process all at once. Bolt-resistant varieties extend the usable window an extra three to four weeks into warming weather.
Common kale pests to watch for in Nevada include Cabbage Worm and Cabbage Looper. The first line of defense is companion planting: Onion and Garlic planted nearby discourage several of these pests by confusing host-plant identification or repelling adults before they can lay eggs. Weekly garden walks in the early morning catch problems when they're still manageable.

Kale Growing Tips for Nevada Gardeners
- •Harvest outer leaves first using the cut-and-come-again method; the central growing point will produce for months.
- •Kale leaves become sweeter after the first frost as plants convert starches to sugars — wait for cold nights for best flavor.
- •Nevada's cool-season kale plants best in October, November, and December for winter and early spring harvest. Spring plantings bolt before producing a harvestable crop.
- •Use floating row covers to block cabbage white butterflies from laying eggs on plants.
