Growing Instructions

Sow directly in late autumn or early spring, or start inside 10-12 weeks before last frost date. Ideal soil temperature for transplanting is 60-65 degrees F. Seedlings can be planted 6 inches deep or hilled once established to preserve the white stems. Space plants 4-8 inches apart.
Seed Saving Instructions

Leeks are biennial, so allow a few stalks to continue to mature for a second year. After flowers have faded and seeds have turned dark, cut stalks and dry in a paper bag. After 3-4 days, shake seeds free and separate from chaff. Label and store in a cool, dry place.
