Sometimes there will be charred leaf edge, leaf tip scorch and other phenomena, which is mostly caused by drought, low temperature, improper watering, fertilization and other physiological diseases.
The prevention and control methods are: improve cultivation management, control temperature and humidity, reasonable fertilization, proper ventilation.
