When to Plant Kohlrabi in West Virginia (2026 Guide)
Kohlrabi is a unique and versatile vegetable that many gardeners in West Virginia may want to consider for their planting plans. This unusual brassica develops a swollen stem just above the soil line, providing a crisp, mild flavor that is delightful in salads, slaws, and cooked dishes alike. With its easy growing conditions and tolerance for cool weather, kohlrabi is an excellent option for both spring and fall planting in your garden.
In West Virginia, especially in areas like Morgantown, gardeners need to be mindful of frost dates to make the most of their kohlrabi harvest. For those in Zone 6a, the last spring frost typically occurs around April 30, while the first fall frost can be expected by October 17. This frost-free season of approximately 170 days allows for ample time to cultivate kohlrabi and plan for staggered planting with other crops.
Kohlrabi thrives in cooler temperatures, making it ideal for early spring or late summer planting. To maximize your harvest, you can start your kohlrabi indoors in late winter before transplanting it outdoors. Proper timing is crucial, as kohlrabi can be sensitive to extreme heat and humidity that can frustrate gardeners in West Virginia over the summer months.
