About Kale

Kale is one of the hardiest vegetables available — it survives hard frosts and tastes sweeter after a freeze.

Sow indoors 4-6 weeks before last frost or direct sow in late summer for fall harvest. Harvest outer leaves to keep the plant producing. Cold-hardy varieties survive winter in Zone 7+.
