How to treat it
Exposure: they like exposures in full sun, even if they can grow without problems even in partial shade, even in a very bright place. They do not fear the cold very much, and can survive even if exposed for short periods at temperatures just below 0 ° C, provided that the cotation sub-layer is kept completely dry. Watering: irrigate with moderation, allowing the substratum to dry perfectly between one watering and the other. With the arrival of the first cold, reduce the watering until it is completely suspended in winter. Soil: it prefers poor and very well-created soils, an ideal substrate can be prepared by mixing universal soil with abundant quantities of sand and coarse-grained material, such as perlite or expanded clay.
