The flavor is notably delicate and sweet, with a subtle complexity that makes them a favorite among chefs and home cooks alike. Their refined appearance makes them ideal for presentation-worthy dishes. Planting Your Carentan Leeks Start seeds indoors 10 to 12 weeks before your last spring frost. Sow seeds in seed trays and maintain consistent moisture until seedlings emerge. When seedlings reach 4 to 6 inches tall, they're ready for transplanting. Space plants 4 to 5 inches apart in rows 10 inches apart. Carentan leeks thrive in full sun and prefer rich, well-draining soil with plenty of organic matter worked in. Care and Maintenance Keep soil consistently moist with about 1 inch of water weekly. As plants develop, gradually earth up soil around the stems to blanch the white shaft and improve tenderness. Apply mulch to conserve moisture and regulate soil temperature. Feed with a balanced fertilizer every three to four weeks to support steady growth and development. Harvesting Your Carentan Leeks These leeks typically mature in 90 to 110 days after transplanting. Harvest when they reach 8 to 12 inches long and about 1 inch in diameter—their ideal size for cooking. Gently loosen the soil and pull straight up.
