Curly kale has green to blue-green leaves that are curled, ruffled or fringed at the edges. The leaves are around 6-8 inches long and have a chewy texture.
Curly kale thrives in cool temperatures between 60-65°F (15-18°C) and can tolerate temperatures as low as 20°F (-7°C). It needs well-draining soil that is rich in nutrients and organic matter. It also requires consistent watering to prevent the leaves from becoming tough and bitter.
Curly kale seeds typically germinate within 5-7 days when the soil temperature is between 60-65°F (15-18°C).
Curly kale can be harvested when the leaves are about the size of your hand. You can either harvest the outer leaves, leaving the inner leaves to continue growing, or you can cut the entire head off at the base. It is important to harvest the leaves before they turn yellow or brown, as this indicates the plant is past its prime.
