1、 Illumination

Threaded iron likes half shade and avoids strong light. It does not have high requirements for light. It is maintained in places with bright astigmatism, with shiny leaves and tender green buds. However, there is no sunshine for a long time, which is not conducive to the growth of threaded iron. Therefore, in spring and autumn, you can bask in the sun in the morning and evening, and in winter, there is full sunlight

2、 Temperature

The most suitable temperature for the growth of screw iron is 15-28 ℃. If the temperature exceeds 30 ℃ in summer, it should be cooled by shading and spraying water. If the temperature is above 0 ℃ in winter, it can survive the winter safely

3、 Watering

Screw iron is relatively drought resistant. In spring, summer and autumn, it can wait for the basin soil surface to turn white, dry and water permeable. In winter, the temperature is low and the plant grows slowly. At ordinary times, keep the basin soil slightly dry and water it when the soil is nearly dry

4、 Humidity

Screw iron likes humidity. If the air is too dry, the leaves of the plant are easy to wilt and roll. Under the condition of good ventilation, spray water frequently to plant leaves and surrounding areas for humidification

5、 Fertilization

With the growth of plants, the basin soil can be changed once a year in spring. When changing the basin, manure or slow-release fertilizer can be buried in the basin bottom. During the growth period, light liquid fertilizer shall be poured once a month. Nitrogen, phosphorus and potassium elements shall be balanced, the concentration shall be light, and thin fertilizer shall be applied frequently

6、 Diseases and insect pests

In the environment of high temperature and high humidity, screw iron loves leaf spot and anthrax, but usually as long as you pay more attention to ventilation, it can play a certain preventive role. In addition, screw thread iron also likes to attract aphids and scale insects, which can be controlled by omethoate and scale Bizhi
