Studies have shown kale to have anti-inflammatory properties, as well potential ability to aid in cancer prevention. In a side-by-side study of different kale varieties, curled kales were shown to have the highest concentration of glucosinolates, which studies have shown to have anti-cancer properties.

When to Grow

Sow seeds outdoors in early spring, 2–4 weeks before your last frost, or late summer for a fall crop. In zones with mild winters, fall-planted kale can be harvested throughout winter. If you’re not sure how to find your first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

How to Sow and Plant

Sow seeds directly into prepared garden beds or containers, planting them 1/4 to 1/2 inch deep. Thin seedlings to 12–18 inches apart once they develop true leaves. Water consistently, keeping soil evenly moist but not soggy.

How to Grow

Maintain moderate soil moisture and fertilize monthly with a nitrogen-rich organic fertilizer. Mulch to suppress weeds and retain moisture. Harvest the outer leaves first, allowing the inner crown to continue producing new growth. Frost improves flavor, making fall harvests especially delicious.

How to Save Seeds

  • Let plants overwinter (kale is biennial and will flower in its second year).
  • Allow flowers to pollinate and form seed pods.
  • Wait for pods to dry and turn brown on the plant.
  • Harvest pods and hang to dry in a well-ventilated area.
  • Crush pods and separate seeds.
  • Store seeds in a cool, dry place in airtight containers.
