Planting: Sow seeds ¼ inch deep, 4-6 inches apart in rows 18-36 inches apart. Thin to 12-24 inches apart after plants produce their third true leaf, maintaining the strongest plants.
Harvest: Pick the outer leaves when they are about 8-10 inches long. Avoid picking the inner leaves to prevent damaging the growing point. Refrigerate or cool quickly for storage. A light frost will bring out the sweetness.
