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.

INTRODUCING LEEK SEEDS

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.

PLANTING LEEK SEEDS

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.

MAINTAINING LEEK PLANTS

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.

Frequently Asked Questions

What are heirloom seeds?

Heirloom seeds are the types of seeds your grandparents grew. These varieties have been passed down from generation to generation. They’re old reliable open-pollinated varieties that aren’t typically grown commercially. Instead, they have a rich history that predates modern breeding techniques. You can learn more about open-pollinated, heirloom, and non-GMO seeds in our Survival Garden Training blog.

How do I know my seeds are fresh?

Every seed packet includes a "packed for" date, and we germination test each seed lot before packaging to ensure you receive viable, high-quality seeds that are ready to grow.

Are your seeds chemically treated?

No, we do not pre-treat our seeds. All of our garden seeds are untreated, open-pollinated, non-GMO, and heirloom varieties. They are kept in temperature-controlled cooler storage until they are packed and shipped to keep them pest and disease-free.

Will your seeds grow in my USDA Hardiness zone?

The seeds in our collections are specifically chosen from varieties that can be successfully grown from Zone 3 to Zone 10 USDA Hardiness Zones. However, individual varieties have specific needs to thrive in different environments. Each seed pack has optimal temperatures for germination and instructions on seed starting. Consult local frost dates to plan your garden and get the most out of your seeds.

What is the shelf life of these garden seeds?

Most seeds remain viable for 3 to 5 years or longer when stored properly. Check your seed packet for specific varieties. For best results, keep your seeds in a cool, dry place away from direct sunlight and moisture. Store them in an airtight container in a consistent temperature environment—a refrigerator or cool basement works well. Proper storage helps maintain germination rates and extends seed life well beyond the packed date.

Where are Survival Garden Seeds sourced?

The majority of our seeds are sourced in the United States, with a few exceptions when the seed is difficult to source domestically. Whenever we do have to source outside of the US, we ensure our seeds are safe to grow, non-GMO, heirloom varieties that meet our standards for germination and reliability.
