When to Plant Kohlrabi in Georgia (2026 Guide)
Kohlrabi is a unique and flavorful vegetable that thrives particularly well in Georgia’s diverse climate. With an ability to withstand cooler temperatures and a growing season that can see frost-free periods stretching from late March to late November, it is a perfect addition to both spring and fall gardens. Knowing when to plant this intriguing brassica can help ensure a bountiful harvest, whether you're in Atlanta or coastal Savannah.
For those in Zone 7a, like Atlanta and Athens, the median last spring frost date is March 29. This timing allows for a successful planting window where kohlrabi can thrive. Conversely, in Zone 6b, which includes areas like Acworth, you will need to be mindful of an earlier last frost date of April 4, meaning timing your planting is crucial for success.
In contrast, the warmer Zone 7b–8a areas such as Albany have a median last frost date as early as March 2, leading to an extended growing season of approximately 268 days. Regardless of your specific location in Georgia, understanding these frost dates is key to cultivating lush, delicious kohlrabi that can enhance your culinary endeavors.
