Cultivation advice 

1. Use well-draining soil rich in organic matter. Leeks prefer a slightly acidic to neutral soil with a pH between 6.0 and 7.5.
2. Start seeds indoors 10-12 weeks before the last expected frost. Transplant seedlings outdoors when they are about 8-10 inches tall.
3. Space ‘Giant Winter’ leeks about 6 inches apart in rows with a spacing of 12-18 inches.
4. Keep the soil consistently moist, especially during dry spells. Leeks prefer regular watering to ensure proper growth.
5. Provide a balanced fertilizer at planting and when leeks are about halfway to maturity. Leeks generally benefit from regular, light feedings.
6. As leeks grow, you can gradually hill soil around the base to blanch the lower portion of the stems. This contributes to a milder flavor and more tender texture.
7. ‘Giant Winter’ leeks are known for their ability to withstand cold temperatures. They can be left in the ground well into the winter months in some regions.
8. Harvest leeks when they reach the desired size. They can be harvested young for a milder taste or left to mature for a stronger flavor. Use a fork or gently pull to harvest.
9. Store harvested leeks in a cool, dark place. Trim the roots and remove damaged outer leaves before storing. ‘Giant Winter’ leeks are known for their good storage qualities.
10. Apply a layer of mulch around leek plants to conserve moisture, suppress weeds, and provide some insulation during colder temperatures.
11. While no plant is completely immune, ‘Giant Winter’ leeks are often resistant to certain diseases. Still, practice good garden hygiene and crop rotation to minimize the risk of diseases.
12. In areas with strong winds, consider staking or supporting the leek plants to prevent bending or breakage.
13. Plant ‘Giant Winter’ leeks alongside other vegetables that complement their growth, such as carrots, celery, and onions.
14. If you wish to save seeds, allow some leeks to bolt and produce flowers. Collect the seeds once the flower heads have dried.
15. Consider planting ‘Giant Winter’ leeks in the fall for overwintering. This can result in larger and more flavorful leeks.
16. Consider providing a phosphorus-rich fertilizer in late summer to promote bulb development and overall plant health.
17. Keep the area around the leek plants free of weeds to reduce competition for nutrients and water.
18. Trim any damaged or yellowing leaves throughout the growing season to encourage the plant’s energy to focus on bulb development.
19. Ensure consistent moisture throughout the growing season, especially during dry spells. Adequate water is crucial for the development of well-formed leeks.
20. Monitor for common leek pests such as aphids and onion maggots. Use organic insecticides if necessary, and consider introducing beneficial insects like ladybugs.
21. While leeks prefer full sun, ‘Giant Winter’ leeks can tolerate partial shade. However, providing as much sunlight as possible will contribute to robust growth.
22. If you plan to store leeks for an extended period, consider harvesting them just before the first hard frost. This can enhance their storage capabilities.
23. Rotate leeks with other crops each season to minimize the risk of soil-borne diseases and pests.
24. Integrate pest-resistant companion plants like marigolds or garlic around your leek beds to help deter pests.
25. Maintain a gardening journal to record planting dates, growth patterns, and any challenges faced. This information can be valuable for future seasons.
