Under normal conditions, when the temperature in winter is kept at about 5 ℃, the T. triangularis can survive normally. However, if the breeding temperature is below 0 ℃ for a long time, it will be frozen to death. The short-term low temperature is easy to be frostbitten, but it will not be frozen to death.
In addition, whether it will be frozen to death is not only related to the temperature, but also to the breeding climate. If the plant has been blown by the cold wind for a long time without any sunshine, it will be more likely to freeze to death. But if there is no cold wind and enough sunshine, it is not easy to freeze to death. Sometimes, even if the temperature is about 5 ℃, but the climate is not stable, there will be a chance of freezing to death. So, don't only care about the temperature during the winter, but also pay attention to other aspects
1. Indoor: when the outdoor temperature is lower than 5 ℃, move to the indoor as soon as possible. And, the position that place also cannot have cold wind, should be able to receive certain light..
2. Antifreeze: when the temperature can not reach, you should cover it with a film or cotton cloth to cover the flowerpot, which can also reduce the probability of frostbite.
