It is worth mentioning that some species of rhipsalis do have small spines or spikes, in their young stage. But, in addition, the rhipsalis are epiphytic cacti : originally they grow on the branches of the trees, from which they hang their long, thin and fleshy stems (it is a succulent plant, like all the cactus) plume. There is another variety or classification of rhipsalis, lithophytes, which have adapted to develop in stones.

• Environment: They require a warm and luminous place, that is to say a light shadow or light filtered but a humid atmosphere. They must also be protected from air currents.
• Temperature: The ideal temperature is between 18 and 20º. In winter, it should not fall below 10 ° since they come from a warm area.
• Substrate: They need rich soil (different from most cacti), fresh, acidic but well drained. The ideal substrate can be made by mixing one third of sand, one third of garden soil and one third of heather soil. You can also use substrate for orchids, for tropical plants.
• Irrigation: You should water regularly, preferably the rainwater is your favorite or decalcified. It is very important to let the earth dry between waterings.
