As the leek is somewhat milder in flavor, many like it as a substitute for winter green onions.
Like onions, it requires a rich, well pulverized soil.
Sow seed in beds in late winter and transplant later, or sow in rows where they are to grow and thin to one plant every 3 to 5 inches. To get long, white shanks, plant in trenches 3 or 4 inches deep and pull soil to them as they grow.
By fall, enough soil should be pulled around them to make a ridge 4 to 5 inches high. Leeks may be left in the open during winter and dug as needed.
