Year-round cultivation at room temperature is possible, then water a little every 3 to 4 weeks. The plants will also flower if they do not have a cool winter dormancy.
However, winter dormancy at 6-12°C is just as possible, in which case the plants should be kept relatively dry from November to March. Three to five times during the dormant period they should be lightly showered on warm days. The brighter the location, the better.
