What To Know
- You have access to a wider selection of leek varieties, from the classic ‘King Richard’ to the milder ‘Tango’.
- Leeks are a cool-season crop, so the best time to sow seeds depends on your climate.
- This technique involves covering the lower part of the leek with soil or mulch to produce a longer, whiter, and sweeter portion.
Leeks, with their mild onion flavor and versatility in the kitchen, are a delicious addition to any garden. But did you know that growing leeks from seed is easier than you might think? This guide will walk you through every step, from sowing seeds to harvesting your own delicious leeks.
The Allure of Growing Leeks from Seed
Starting leeks from seed offers several advantages over buying seedlings:
- Variety: You have access to a wider selection of leek varieties, from the classic ‘King Richard’ to the milder ‘Tango’.
- Cost-Effectiveness: Growing from seed is often cheaper than buying seedlings, especially if you plan to grow a large quantity.
- Control: You can choose the exact time to sow your seeds, ensuring your leeks are ready for harvest at the perfect moment.
Choosing the Right Leek Variety
Before you start, consider the type of leek you want to grow:
- Early Maturing: These varieties, like ‘King Richard’ and ‘Musselburgh’, are ready for harvest in around 100 days. Ideal for shorter growing seasons.
- Mid-Season: Varieties like ‘Tango’ and ‘Winter Giant’ take around 120-130 days to mature. They offer a good balance of flavor and size.
- Late Maturing: These varieties, like ‘Elephant’ and ‘Giant Musselburgh’, take 150 days or more to mature. They produce the largest leeks, perfect for winter storage.
Sowing Your Leek Seeds
Timing is Key: Leeks are a cool-season crop, so the best time to sow seeds depends on your climate:
- Spring: Sow seeds indoors 6-8 weeks before the last frost, then transplant seedlings outdoors.
- Fall: Direct sow seeds in the fall for a spring harvest.
Setting Up Your Seedlings:
1. Choose a Seed Starting Mix: Use a seed starting mix that drains well.
2. Fill Seed Trays or Pots: Fill your chosen containers with the seed starting mix and gently moisten.
3. Sow Seeds: Place one or two seeds per cell or pot. Cover seeds with a thin layer of soil (about ¼ inch).
4. Water Gently: Water the seeds lightly, ensuring the soil is consistently moist but not soggy.
5. Provide Light: Place the seed trays or pots in a bright location, but avoid direct sunlight.
6. Maintain Temperature: Keep the temperature between 65-70°F.
Transplanting Your Leek Seedlings
Once your seedlings have developed a few true leaves (usually 4-6 weeks after sowing), it’s time to transplant them outdoors.
Preparing the Garden Bed:
1. Choose a Sunny Spot: Leeks prefer full sun to partial shade.
2. Soil Preparation: Leeks thrive in rich, well-drained soil. Amend your soil with compost or aged manure for optimal growth.
3. Create Rows: Space your rows 12-18 inches apart.
4. Dig Furrows: Dig furrows 6-8 inches deep and 4-6 inches wide.
Transplanting:
1. Harden Off: Gradually acclimate your seedlings to outdoor conditions by placing them outside for increasing periods of time over a week.
2. Space Seedlings: Space seedlings 6-8 inches apart in the furrows.
3. Water Thoroughly: Immediately water the transplanted seedlings to help them settle in.
Caring for Your Leeks
Once your leeks are in the ground, regular care will ensure a bountiful harvest:
Watering: Leeks prefer consistent moisture, so water deeply and regularly, especially during dry periods.
Fertilizing: Feed your leeks with a balanced fertilizer every few weeks, especially during the early stages of growth.
Blanching: This technique involves covering the lower part of the leek with soil or mulch to produce a longer, whiter, and sweeter portion. Start blanching when the leeks are about 6 inches tall, gradually adding soil as they grow.
Weed Control: Keep weeds under control, as they compete with your leeks for nutrients and water.
Pest Control: Leeks are relatively pest-free, but watch out for aphids, onion flies, and slugs. Use organic pest control methods if necessary.
Harvesting Your Leeks
Leeks are ready for harvest when they reach the desired size, typically 1-2 inches in diameter. The best time to harvest is in the fall or early winter before the ground freezes.
Harvesting:
1. Cut the Leeks: Use a sharp knife to cut the leeks just above the soil line.
2. Store Properly: Store harvested leeks in a cool, dry place for up to several months.
Beyond the Basics: Tips for Success
- Start Early: Leeks are a cool-season crop, so starting them early in the season will give them a head start.
- Protect from Frost: Cover your leeks with row covers or frost blankets during cold weather to protect them from damage.
- Consider Companion Planting: Leeks benefit from companion plants like carrots, lettuce, and spinach.
From Garden to Plate: Enjoying Your Homegrown Leeks
Leeks are a versatile ingredient that can be added to soups, stews, stir-fries, and more. They can be roasted, sautéed, grilled, or used in savory pies and quiches.
A Bountiful Harvest: The Rewards of Growing Leeks from Seed
Growing leeks from seed is a rewarding experience. You’ll enjoy the satisfaction of nurturing your own plants from tiny seeds to towering vegetables. The fresh, flavorful leeks you harvest will add a delicious touch to your meals, reminding you of the joy of gardening.
What People Want to Know
Q: Can I grow leeks in containers?
A: Yes, you can grow leeks in containers, but they will require larger pots (at least 12 inches in diameter) to accommodate their root systems.

A: Use row covers to prevent onion flies from laying eggs on your leeks. You can also try companion planting with herbs like rosemary and thyme, which are thought to deter onion flies.
Q: When is the best time to harvest leeks?
A: The best time to harvest leeks is in the fall or early winter, before the ground freezes. You can continue to harvest leeks throughout the winter if you cover them with mulch or row covers.
Q: Can I save leek seeds from my harvest?
A: Yes, you can save leek seeds from your harvest. However, it’s important to note that leek seeds are often hybrid, meaning that the offspring may not be true to type.
Q: What are some other tips for growing leeks from seed?
A: Ensure your soil is well-drained, as leeks are susceptible to root rot. Also, consider using a starter solution to give your seedlings an extra boost during their early growth stages.
