How to Grow Leek
Overview
Leeks are a delicious and versatile vegetable that are easy to grow in your home garden. A member of the allium family, which includes onions, garlic, and shallots, leeks have a mild flavor that adds depth to many dishes.
Growing Conditions
Leeks thrive in cool temperatures and prefer full sun but can tolerate partial shade. They are well-suited for climates with moderate winters and springs. Leeks require moist soil rich in organic matter and have a long growing season of 120-150 days from planting to harvest.
Planting & Care
Start leek seeds indoors about 10 weeks before the last expected frost date, or purchase young transplants if available. Plant seedlings outdoors when they reach 6 inches tall, spacing them 12-18 inches apart in rows spaced 12-18 inches apart. Keep soil consistently moist and mulch around plants to retain moisture. As stalks grow, hill up soil around the bases to blanch the stems for a sweeter flavor.
Common Problems
Leek pests are usually not a problem, but watch out for aphids or slugs in early spring. If needed, use organic insecticidal soap or handpick off pests. Leeks may also bolt or go to seed in hot weather, producing small, bitter stalks; harvest promptly and plant new ones as soon as possible.
Harvest or Enjoy
Leeks are ready to harvest when they reach 1 inch in diameter at soil level. Pull up the entire plant by its leaves, being careful not to damage the remaining roots. Trim roots and cut off any damaged leaves before storing unwashed leeks for a week or more in the refrigerator. Use fresh leeks within a few days to enjoy their maximum flavor and nutrients.
