Chives autumn tube rooting is the key

The growth of leeks during the winter dormancy period mainly relies on the nutrients stored in their roots and bulbs from the previous autumn. Therefore, maintaining healthy alfalfa roots during the fall is crucial for the successful protection and growth of leeks. Two top-dressing applications are typically recommended in late August and mid-September. For each 667 square meters, you can apply 1,500 kg of well-composted manure or 150–200 kg of cooked cake fertilizer, along with 20 kg of 45% compound fertilizer. This ensures that the plants have enough nutrients to support their development through the colder months. Proper watering is essential during this time. In September, the soil should remain consistently moist but not waterlogged. Watering every seven days is usually sufficient. By October, a balance between wet and dry conditions is ideal—avoid both drought and overwatering. For leeks that need to "sleep" (enter dormancy), it's important to prevent excessive moisture, which could lead to soft, unproductive growth. A final watering should be done 15–20 days before the ground freezes. This irrigation provides the necessary moisture for long-term root health and growth. If using a greenhouse, avoid watering near the plastic cover, as it can increase humidity too much and slow down temperature rise, making it harder to manage soil compaction. For leeks not intended for deep dormancy, maintain consistent watering to keep the stems and leaves fresh, ensuring a good harvest before the plants begin to bend or weaken.
