Nowadays, the safety of leek has become an important topic of public concern. The emergence of phenomena such as "poisonous leek" and "shedding root of leek" makes people feel frightened about leek. So in order to ensure that we can eat leeks at ease, we can build a private vegetable garden. Growing vegetables invisibly plays a role in physical exercise and can stimulate enthusiasm for life.

To grow safe leeks, you need to master the following points:

1. Sowing seeds

Dry seeds are mainly used for direct seeding in spring, and the seeds can also be soaked in warm water of about 40 ℃ for 12 hours before sowing. It is appropriate to promote germination in summer and autumn. Generally soak the seeds in 25 ℃ warm water for 12 hours one week in advance. After washing, wrap them in a wrung-dry wet cloth, place them in a 15-20 ℃ environment, rinse them with clean water twice a day, and sow more than half of the seeds 3 days later when they are exposed to white. Strip sowing, hole sowing and sowing are all suitable. The soil is covered with about 2cm, slightly compacted, placed in a cool and ventilated place, and germinated for 1-3 weeks.

Before the seedling height 20cm, generally once a week watering, pay attention to no stagnant water, there are weeds should be pulled out immediately.

3. Colonization

When the plant has 7-9 leaves, it can be planted. Cloudy days are the most suitable for planting.

After the beginning of harvest, add once in about 20 days, and topdressing each time after harvest.

5. Ramet propagation

Ramet propagation is usually carried out in April, carefully dig up the whole cluster of leek roots that have been more than 2 years old, remove the dried leaves and fibrous roots, 1 part is about 10-15 plants, the leaves are cut to 10~15cm and planted, the interval is about 15cm, and water is watered after planting.

6. Harvest

When the leek grows to about 25cm, it can be harvested basically, and it can be harvested again after 1 month. Do not harvest immediately after watering or spraying, and it is not suitable to harvest in summer. A sunny day is the best time to harvest. Use clean scissors to cut off the leek at the sheath about 3cm from the soil. The soil was loosened once after harvest and watered when the incision healed 2-3 days later. At this time, it is best to apply once mature organic fertilizer. Leek is perennial, and the harvest period is as long as 2-3 times. when the plant is aging and its growth becomes weak, it should be renewed or re-sown.
