Methods and steps:

1. Soak leek seeds in warm water at about 55 ~ 60℃ 10 ~ 15 minutes? After the time is up, wash the seeds with clear water, take them out and dry them in the shade for later use.

2. Select a 50-hole seedling tray, spread a layer of coconut bran on the bottom of the tray, then put sterilized organic substrate or prepared nutrient soil, sow about 6 seeds per tray, then cover with a layer of substrate or soil with a thickness of about 0.5-1.0cm, water, and keep the temperature at 15-25℃, so that seedlings can emerge in about one week.

3. You can also dig leek roots that have grown for two or three years directly from the vegetable garden, leaving only the root system about 1.5 to 2.0 cm. After cleaning the root soil, soak it in potassium permanganate 1.500 times for disinfection, then rinse the root with clean water and plant it in a pot.

4. After emergence, put pots and other containers for potted plants into the substrate or nutrient soil, leaving a space of about 3 to 4 cm above. Then plant a clump of leek seedlings every five to six trees, with a spacing of about 4cm. Then water it, and it will take about one to two weeks to slow down the seedlings.

The leek seedlings grow to a height of about 30 cm, and can be cut off when they grow yellow leaves. This is called stubble. After two or three stubbles, leeks will enter the high-speed growth period, and then they can be cut and eaten.

6. Don't use any chemical fertilizers and pesticides during the whole growth period, just use some rice washing water or kitchen waste such as leftover milk and beer, and topdressing once every two weeks. Don't be too diligent, not too much at a time. It should be combined with watering.

Attention: Don't water too much, it will cause diseases.
