When to Plant Kohlrabi in Mississippi (2026 Guide)
Kohlrabi is a unique and versatile vegetable that can thrive in Mississippi's varied climate. With its crunchy, bulb-like stem and mild flavor reminiscent of broccoli, this brassica is perfect for both spring and fall planting. In Mississippi, the median last spring frost date varies: in Zone 7a, it's March 26, while in Zone 7b–8a, it's even earlier at March 3. Understanding these dates is crucial for successful kohlrabi cultivation.
This cool-weather crop is easy to grow, requiring only 45–60 days from transplant to harvest. Whether you're in the bustling city of Jackson or enjoying life in coastal Biloxi, knowing when to start your kohlrabi will ensure a bountiful harvest. By planting at the right time, typically starting indoors in late winter or directly sowing outside after frost risks, you can enjoy delicious, fresh kohlrabi throughout the growing season.
For those in warmer areas of Mississippi, like Hattiesburg, fall planting is also an option. Consider the longer frost-free season of approximately 268 days in Zone 7b–8a, allowing for multiple sowings.
