Causes of death and key points of maintenance of jasmine in winter
The cause of death of Riley in winter: first, freezing injury: when the temperature (room temperature) was lower than 3-5 ℃, the physiological function of the plant was damaged; when it dropped to 3 ℃, it would cause the whole plant to die. Second, the basin soil is too wet: when the temperature (room temperature) is below 10 ℃, Riley is in a dormant state, and the basin soil water demand is less. If too much watering, Riley root system for a long time in the condition of no ventilation, it is easy to suffocate to death. Third, the basin soil is too dry: if it is not watered for a long time, Riley will dry up and die. In order to make Riley safe through the winter, we must do a good job of anti-freezing.
