1、 Fertile soil

Most of the nutrients of potted leeks come from the soil, so we should choose fertile soil for planting. If we choose poor soil, it is easy to grow poorly, and the plant is even less likely to grow strong. Not only should the soil be selected well, but also a certain amount of base fertilizer should be added in order to increase nutrition, so as to ensure the needs of growth

2、 Planting density

Space can affect growth. If potted plants are planted, the space is relatively small and nutrients are difficult to distribute. If the plants are planted densely and the number of plants is relatively large, nutrients are naturally not enough. When transplanting, it can be sparse. Five or six trees can be clustered together, and a certain distance can be maintained to ensure the distribution and supply of nutrients

3、 Timely topdressing

If you want to plant strong, in addition to the application of base fertilizer, you also need to topdressing in time during growth. If you lack nutrients, the whole leek will become thinner and the leaves will turn yellow. It can be supplemented by topdressing foliar fertilizer, mainly nitrogen fertilizer, but the proportion of other elements should be reasonable and balanced, and special foliar fertilizer can be used

4、 Temperature control

The temperature is also very important. We should ensure the temperature and maintain the temperature between 12-30 ℃. This range is most conducive to growth and make it strong
