So how to grow leeks to grow strong? Let's take a look together next!
Leek planting tips
One is the choice of planting materials. Leek can be planted not only by planting, but also by transplanting leek roots. If it is planted by seeding, it will take at least two years from seeding to growth, which is relatively long, so it is generally not recommended to plant this way. The use of leek roots is very simple and effective. Just transplant the leek seedlings on the soil block. In this way, the transplanted leek roots very quickly and the ramification is very strong. It can be harvested in two to three months. It should be noted that such leeks must be divided in time to avoid mutual shade and competition for nutrients. So plant it now and you can harvest it during the New Year.

Second, fertilizer and water management. Leeks are generally suitable for growing in fertile soil, and the soil can be dug directly from the planting site. It is necessary to avoid the previous crops being onions and garlic, so as not to carry bacteria and affect growth. Before planting, you can apply some organic fertilizers, such as diammonium phosphate, or use plant ash, organic fertilizer can be released slowly, and the number of top dressing can be appropriately reduced. Plant ash is rich in potassium, which is beneficial to the rooting of leeks and has a good effect. Leek is water-loving and drought-tolerant, but only enough water can guarantee the taste of leeks. In addition, every time leeks are harvested, liquid fertilizer with high nitrogen content needs to be applied. Applying more nitrogen and potassium fertilizers is conducive to the growth of leeks, but less application Or no phosphate fertilizer.

Third, the prevention and control of pests and diseases. Generally, leeks will cause pests, among which pests include leek maggots, leaf miners, and thrips. Leek maggots mainly damage rhizomes and cause bulb rot, while the latter two mainly gnaw on leaves. Once it is discovered that root irrigation can be used to control the leek maggots, trichlorfon can be used to control leek maggots, or spraying can also be used. For example, 2.5% deltamethrin 1000-1500 times liquid spray can prevent leaf miners and thrips.
Fourth, harvest in time. The leeks in the growth period can be harvested when the height reaches about 25cm, and it can be harvested every half a month. It should be harvested in the morning or evening, and the cut should be kept as flat and consistent as possible, so as not to lose too much water. There is a proverb called quick knife flat mud cutting, which refers to the height of the harvest of leeks, which can help its regeneration. Three days after harvesting, water should be thoroughly watered once, and appropriate amount of urea can be applied along with the water to restore the growth of leeks as soon as possible.
