How to grow kale and what to pay attention to

1. Maintenance methods

1. Soil: Chinese kale has strong adaptability to soil, with sandy loam being the best. It needs to absorb a large amount of nitrogen, phosphorus and potassium. When the plants are young sprouts, they absorb a lot of fertilizer. The absorption of fertilizer varies in different periods of growth, so you need to make appropriate adjustments.

2. Temperature: Kale prefers a mild growing environment and has strong heat resistance. The best growing environment is between 25 and 30 degrees. The growth is relatively slow below 20 degrees, and the growth of kale also requires a larger temperature difference between day and night.

3. Light: It is a light-loving plant and has high requirements for light during the growth period. It needs sufficient sunlight and cannot tolerate dark environments.

4. Water: It likes a relatively moist growing environment, and the soil needs a lot of water during the growing period. Compared with other vegetables, it is more resistant to waterlogging, but excessively moist soil or waterlogging will affect root growth.

2. Breeding techniques

1. Sowing: You can use direct seeding or seedling cultivation. The seedlings should be grown in sandy loam that is good for drainage and air permeability. When preparing the land, apply more fertilizer to provide sufficient nutrients for kale.

2. Overwintering: Chinese kale likes a warm and humid environment. In winter, certain warming measures should be taken to avoid freezing of the roots.

3. Problem diagnosis and treatment

1. Diseases: Chinese kale is prone to black rot, which is caused by bacteria and is prone to occur under high temperature and high humidity conditions. When the disease occurs, it will cause the leaves to die. When discovered, it must be removed in time and sprayed with fungicide for treatment.

2. Pests: Common pests include cabbage loopers and aphids. If found, they must be isolated in time to avoid contamination of other branches and leaves. During the seedling stage, spray insecticide or a thousand times solution of dichlorodiphenyltrichloroethane.

IV. Other issues

1. Is it poisonous? The flower stalks and young leaves of kale are edible, refreshing and delicious, so they are non-toxic and can be cultivated with confidence.

2. Whether to grow indoors: Since kale is a light-loving plant, it needs sufficient sunlight to grow, otherwise it will affect the growth of the plant. Therefore, it is not recommended to grow it indoors. It is generally best to choose a place with sufficient sunlight and good ventilation.
