Kohlrabi is an unusual brassica that forms a swollen stem above ground with a mild, sweet turnip-like flavor. Both the bulb and tender leaves are edible.
Cottle County, Texas is in USDA Zone 7b. The average last spring frost is March 30 and the first fall frost is November 9, giving you a growing season of approximately 224 days.
At an elevation of 3,553 feet, Cottle County receives approximately 59.3 inches of rainfall annually with predominantly sandy loam soil.

Kohlrabi Heat Requirements (GDD)
What are Growing Degree Days (GDD)?
Growing Degree Days measure the total warmth your plants receive during the growing season. Think of it as a "heat bank" — every day above 50°F deposits warmth that helps your plants grow.
Each plant needs a certain amount of accumulated heat to mature. If your county provides more GDD than the plant needs, it's a great fit. If it's close, you may want to choose faster-maturing varieties or start seeds indoors to get a head start.
