1. Temperature: when maintaining it, it is very important to maintain the temperature of the environment, because it is not resistant to cold and heat. The maintenance temperature should be about 25 degrees. If the temperature is higher than 32 degrees, the plant will stop growing. If the temperature is lower than minus one degree, the plant will be frozen.
2. Watering: observe the soil state first when watering each time. Only when the soil is completely dry, watering is needed. When watering each time, the soil should be completely watered, and at the same time, water in the soil should be avoided.
