1、 Adjust temperature
The best growth temperature of Platycodon grandiflorum is about 15 degrees to 18 degrees. The temperature in early spring is unstable. If there is low temperature weather, keep it warm. In early spring, it's best not to put it outside for maintenance. If it is maintained indoors, the growth environment temperature should not be higher than 18 degrees. If it exceeds the temperature tolerance limit, it will not grow p>
2、 Controlled watering
At this time, it is the peak period of its growth, and the demand for water is relatively large, but the amount of watering should be controlled. If the water is poured too much, its root respiration will be blocked and the root will rot. Drip irrigation method can be used for watering. The water poured by drip irrigation method is relatively uniform, which is conducive to plant absorption p>
3、 Pay attention to the environment
Although it likes humid growth environment, it should avoid high temperature and humid environment. Growing in such environment is easy to cause fungal invasion and tissue damage p>
4、 Reasonable illumination
In the growth period, we should ensure sufficient light to grow healthily. Reasonable light is good for its roots, branches and leaves. It's best to ensure no less than six hours of natural light exposure every day. The sunshine in early spring is mild and can be raised in a sunny place to receive all day light, which can not only meet its lighting requirements, but also increase the temperature p>
