How cold can ginger lilies tolerate?
Today's editor introduces the related content of how cold ginger lilies can tolerate, which will surely bring you help. Let's learn about it together!
How cold can ginger lilies tolerate?
Ginger lilies can withstand a minimum temperature of 5 degrees Celsius. The suitable growth temperature is between 20-35 degrees Celsius, and the overwintering temperature should be above 15 degrees Celsius. If the temperature is consistently below 15 degrees, the growth rate will slow down or even stop, entering a dormant state.
Ginger lilies are susceptible to frost because they have poor cold tolerance and will freeze and die when the temperature drops. Therefore, in winter, ginger lilies need to be moved indoors, and the indoor temperature should be kept above 10 degrees Celsius to ensure they can survive the winter safely.
Temperature tolerance of ginger lilies
1. Growth temperature
Ginger lilies originally grew in the Chiang Mai region of Thailand and are a tropical herbaceous flower. They prefer a warm and slightly humid environment with plenty of sunlight. It is best to provide a temperature of 20-35 degrees Celsius during the growing period, with a maximum tolerance of 38 degrees Celsius, and relatively poor cold tolerance.
2. Overwintering temperature
Ginger lilies are warm-loving and sensitive to low temperatures. The overwintering temperature should be above 15 degrees Celsius. If the temperature is consistently below 15 degrees, the growth rate will slow down or even stop, entering a dormant state.
3. Minimum cold tolerance temperature
Ginger lilies can withstand a minimum temperature of 5 degrees Celsius, but only for short periods of 5 degrees Celsius. If the duration is too long, they can easily freeze to death. Therefore, after the temperature drops in winter, ginger lilies should be moved to a warm environment to survive the winter smoothly.
Overwintering care for ginger lilies
1. Watering: In winter, the temperature is low, and ginger lilies require less water. Water them once every 5-7 days to keep the soil moist, avoiding excessive watering that could lead to waterlogging issues due to accumulated water in the pot.
2. Sunlight: In winter, there is less sunlight, but ginger lilies need more than 5 hours of sunlight each day. They should be placed in a location with plenty of sunlight, and during the noon hours, they can be placed near a window or on a balcony to increase sunlight exposure.
3. Ventilation: Ventilation is very important for ginger lilies. In winter, they should be placed in a location with good ventilation. Since the temperature in the ventilated area is low, it is sufficient to place them there for 5 hours a day.
