Watering: It requires light but regular waterings in the Summer, but let the soil mix dry between waterings. Do not overwater (rot prone), it must be strictly kept dry throughout the winter. Hardiness: Not highly tolerant of a great deal of frost. They need to be kept in a cool place during winter rest and are resistant to light frost if kept on the dry side prior to, and during, cold weather (they are hardy to -2°C short periods).
