Leeks

Leeks are a flavorful, mild-tasting vegetable belonging to the Allium genus, closely related to onions, garlic, and shallots. They are known for their long, white, and tender stalks that are used in various culinary applications.

Starting Leek Plants

Leeks are typically started from seeds, either indoors or directly in the garden.

Indoor Seed Starting

Start seeds indoors 8-12 weeks before the last frost date in your area.

1. Sow seeds 1/4 inch deep in seed-starting trays filled with a well-draining potting mix.
2. Keep the soil moist and maintain a temperature between 60-70°F (15-21°C) for optimal germination.
3. Seedlings will emerge in 10-14 days.
4. Transplant seedlings to the garden after the risk of frost has passed and they have developed several true leaves.

Direct Sowing

• Sow seeds directly in the garden 4-6 weeks before the last frost date.
• Plant seeds 1/4 inch deep and 1 inch apart in rows 12-18 inches apart.
• Thin seedlings to 4-6 inches apart when they are 2-3 inches tall.

Harvesting Leeks

• Leeks are typically ready for harvest 70-120 days after planting, depending on the variety and growing conditions.
• Harvest leeks when the stalks are 1-2 inches in diameter and the leaves are dark green.
• Gently loosen the soil around the base of the leek with a garden fork and pull the plant from the ground.
• Trim the roots and remove any damaged or discolored leaves.
• Leeks can be harvested as needed throughout the growing season.

Harvesting Leek Seeds

Leeks are biennial plants, meaning they will produce seeds in their second year of growth.

1. In the second year, allow a few leek plants to flower and develop seed heads.
2. When the seed heads turn brown and dry, cut them off and place them in a paper bag.
3. Hang the bag in a dry, well-ventilated area for 1-2 weeks to allow the seeds to fully mature.
4. Crush the dried seed heads and sift out the seeds.
5. Store the seeds in an airtight container in a cool, dry place for future planting.
