When to Plant Kohlrabi in Nevada (2026 Guide)
Kohlrabi is an exceptional vegetable for gardeners in Nevada, known for its unique bulb-like stem that is crisp and has a refreshing flavor. Its adaptability to cooler climates, similar to that of broccoli and cabbage, makes it an ideal choice for both spring and fall planting. In Nevada, knowing your local frost dates is crucial, especially since areas like Las Vegas see their last frost as early as February 16, allowing early sowing of this delightful vegetable.
For those in the warmer southern parts of the state, such as Henderson, the median last spring frost occurs even earlier on February 2. This extended frost-free season of approximately 314 days allows for multiple plantings of kohlrabi. Conversely, cooler areas like Reno have a last spring frost date of May 22, requiring careful timing to ensure successful harvests.
Regardless of your location in Nevada, kohlrabi offers a flavorful addition to your garden and kitchen. With just 45-60 days required from transplant to harvest, it's a fast-growing option that thrives during the productive spring and fall months. Whether you're making slaws, roasting, or braising, kohlrabi is versatile and easy to grow.

Common Mistakes Growing Kohlrabi in Nevada
- One common mistake Nevada gardeners make is waiting too long to harvest kohlrabi. If left too long in the ground, the bulbs can become woody, significantly diminishing their flavor. Harvest when they are about 3 inches in diameter for the best taste.
- Many gardeners in the hotter regions of Nevada, such as Las Vegas, forget that kohlrabi still needs cooler growing conditions, especially early in the season. Starting seeds too late can lead to heat stress on the plants, limiting growth and flavor.
- In Nevada, some gardeners mistakenly direct sow in heavy clay soil without proper amendment, which can impact kohlrabi's growth negatively. It's essential to improve soil drainage and fertility with compost or other organic materials to promote healthy plants.
- A frequent issue in Nevada's varying climates is planting too late in the spring in cooler areas, like Reno. Given the last frost date of May 22, gardeners must start early indoors or risk missing the right growing window for kohlrabi.
- Some gardeners disregard the edible leaves of kohlrabi, thinking they are merely by-products. In reality, the leaves are nutritious and can be used in various dishes, such as stir-fries and soups, maximizing the value of your garden.
