Analysis of the Effects of Temperature and Humidity in Cold Orchid (Cymbidium kanran) Care

SuitableCold OrchidThe optimal temperature for growth is 20-25°C. If the daytime temperature exceeds 30°C, growth will stop. Therefore, if using a greenhousecultivation, to prevent the indoor temperature from getting too high, in addition to shading, attention must also be paid to good ventilation to lower the room temperature. In winter, the temperature must not fall below 5°C; heating must be added to prevent the roots from suffering cold damage. If the humidity is too high and combined with high temperatures, the orchid plants are prone to attack by pathogenic bacteria, which has an adverse effect on growth. When it is cold and dry in winter, a humidifier can be used to adjust the humidity. (You Chongkui)
