Why does the cabbage only grow taller but not leaves? (How to deal with it only growing taller but not thicker)

Chinese cabbage has a crisp taste, is easy to digest and is very nutritious. It is a delicious vegetable, especially for the elderly and young children. Therefore, it is the first choice for many vegetable growers in an environment with suitable temperature for growth.

In addition, it has a short growth cycle and does not require a lot of fertilizer, so you can grow fresh and delicious Chinese cabbage yourself.

What are the growing conditions for Chinese cabbage?

1. Temperature and humidity

In the north, changes in natural temperature, whether up or down, will affect its growth rate.

The best growing temperature for Chinese cabbage is 23 to 30 degrees during the day, not lower than 15 degrees at night, and the relative humidity should not be higher than 80% .

This can prevent the leaves from rotting or yellowing, which will affect the appearance, and improve the quality of growth.

2. Ventilation and lighting

When growing Chinese cabbage in a closed environment, it is necessary to ventilate frequently and increase the light exposure time. If the ventilation effect is poor, the local humidity will definitely increase and affect the natural growth of the leaves.

Therefore, in a closed growth environment, it is necessary to ventilate frequently and increase the light time. This can promote rapid evaporation of water in the soil, improve soil permeability, and promote root growth .

3. Soil

When planting Chinese cabbage, you need to choose a plot with rich soil and good water and fertilizer retention. This is the basic factor to improve the growth quality. The growth quality of Chinese cabbage planted in poor soil and rich soil will be very different, affecting the yield.

Therefore, before planting, the soil should be deeply plowed and the soil environment should be improved to create an advantageous growth environment for the roots of Chinese cabbage.

What to do if the cabbage only grows taller but not leaves

Generally, after sprouting, Chinese cabbage will naturally grow new leaves, that is, true leaves, as long as the temperature and humidity are suitable.

If the seedlings fall over or the leaves turn yellow after emergence, it is related to the unsuitable growth temperature and humidity. To make the cabbage grow faster, have higher yield, better quality and more fragrant, you should pay attention to the following aspects:

1. Sow seeds in an environment suitable for growth .

2. Seed selection: Since there are many varieties of pakchoy, choose the appropriate variety according to actual needs .

3. The sowing density should be appropriate. The higher the density, the slower the growth and the more likely the plant to fall over or have slow leaf division .

4. Don't rush to water heavily after the seedlings emerge. Do not water until the soil is dry .

[Summary] In order to prevent uneven planting density of Chinese cabbage, you can use fine sand to mix with the seeds and then spread them, which can effectively prevent the occurrence of uneven density.

The growth cycle of Chinese cabbage is short and it can be harvested in 30 to 40 days. During the growing period, topdressing should be done, mainly nitrogen fertilizer, once every 7 to 10 days and combined with watering to prevent root burn .
