Leek Seeds

Leek seeds develop into hardy, flavorful vegetables used in kitchens around the world. Known for their mild oniony flavor and long stalks, leeks grow much bigger than green onions and have a somewhat sweet aroma. The leek plant enjoys full sun and prefers well-drained, fertile soil, and can tolerate some shade as well, especially in hot climates. This is a biennial plant but is often grown as an annual. It requires consistent care to produce its long, white stems.

Leeks are valued for their delicate, sweet onion flavor, useful in a wide array of culinary dishes. Leeks are part of the Allium family and are a close relative to onions and garlic. They’ve been cultivated for their edible stems and leaves for a long time. Native to the Mediterranean and Middle East, leeks have adapted to other climates, and today they’re suitable for growing in USDA hardiness zones 5 to 9.


You can start by planting your leek seeds indoors 10-12 weeks before the last frost. They can also be sown directly in the garden in early spring or late summer to obtain a fall harvest. Plant seeds 1/2 inch deep. Leeks need consistent moisture to develop their long, white stems, so regular watering is crucial for them. Mulching is a good technique to retain the soil moisture. When seedlings reach pencil thickness, transplant them into the garden. Space them 6 inches apart, planting them deeply and mounding the soil to prevent stems from developing green color due to photosynthesis. This process is called stem blanching and allows you to have a longer white, tender stalk for cooking.


Leeks are relatively easy to care for. To get the best results, grow them in a spot with full sun during the day. Ensure the soil remains moist while growing, and add organic matter and mulch around them. Leeks are ready for harvest when their stems reach about 1 inch in diameter. They can also be picked earlier, for use as baby leeks.

With Survival Garden Seeds, you can anticipate home-grown leeks for fresh, healthy flavor year round. A supply of these tasty vegetables will inspire your cooking and save you a lot of money in the grocery store. Add these versatile plants to your home garden to reap a rewarding crop of delicious leeks.
