Learn about cold tolerance, harvesting after frost, and choosing the right growing conditions for Cold Hardy Kale.
Many kale varieties tolerate light frost, and cool conditions can improve the flavor of some varieties. However, survival during prolonged freezes depends on the cultivar, plant maturity, exposure, and growing conditions. Check the seed supplier's hardiness information before relying on a specific minimum temperature.
Kale can develop a sweeter flavor after exposure to cool temperatures. Cold conditions can cause the plant to accumulate soluble sugars, which may reduce the perception of bitterness. The effect varies by variety and growing conditions, and severe freezing can damage leaves rather than improve their quality.
Harvest the larger outer leaves first and leave the central growing point and younger leaves intact. Avoid removing too many leaves at once, as the plant needs healthy foliage to continue growing. Regularly inspect the plant for pests, damaged leaves, and signs of environmental stress.
