2. Watering: The soil should be kept moist at ordinary times. The soil in the pot should not be too dry or have water accumulation. Especially during the flowering period, water should be added in time when it is dry. In the hot season, more water should be sprinkled to increase the humidity and avoid water shortage.

3. Temperature: It likes warmth and is not cold-resistant, so you should pay attention to controlling the temperature above 8 degrees in winter, otherwise it will cause frost damage and affect its growth. However, you should also pay attention to ventilation in summer when the temperature is high.

4. Light: It likes light, and the color of the flowers will be more colorful with sufficient light. But the light is strong in summer, so be careful to block it. In winter, keep it in the sun as much as possible and provide enough light time.
