From the middle of May to the end of September they like to be kept outdoors, however, direct sun should be avoided. From November to March Disocacti and Disophyllum should not be kept too cold. About 15°C would be the best. They should be well fertilized especially after flowering. They need a bit more water as most of the other cacti and other succulents. If it is very hot, they can be watered twice a week. During winter you don`t have to water so often.
