First, prepare a bed that is 2 meters wide, oriented east to west for optimal wind protection during winter. Raise the edges of the bed on both sides by 15 to 20 cm to improve drainage and support plant growth. Then, apply 5,000 to 7,500 kg of fully composted organic fertilizer per mu (approximately 667 square meters) and thoroughly mix it into the soil. Level the surface carefully to ensure even water distribution and proper root development.
If you are preparing to plant old calluses, start by removing the root plate at the base of each callus. Sort them based on height and thickness, and then plant them in rows with a spacing of 30 to 40 plants per ditch. Each ditch should be 15 cm wide and 28 to 32 cm deep. Make sure the planting depth does not exceed the sheath of the callus to avoid damage. For small seedlings, wait until they reach about 20 cm in height and have 3 to 5 true leaves before transplanting.
After planting leeks, water them 2 to 3 times consecutively to help them establish strong roots and increase survival rates. After each watering, apply 15 to 20 kg of compound fertilizer per acre to encourage leaf growth. This will provide essential nutrients that support the development of the pseudo-stem and strengthen the root system, ensuring healthy and vigorous plant growth in the long run.
