How to Care for the Plant
Water
The sausage-like stem will do well will take a reasonable amount of water in hot weather, when they grow (about once a week). It needs to be kept drier in winter (when the leaves drop) and whenever not growing actively. However, this species seems to hate being wet for any extended period, and can rot easily (especially in winter) if overwatered.
Fertilizer
Fertilize every two weeks with a diluted balanced liquid fertilizer during its growing season in the spring and summer. Avoid fertilizing your plant during the fall and winter months.
Sunlight
It can tolerate moderate shade, and a plant that has been growing in shade should be slowly hardened off before placing it in full sun as the plant will be severely scorched if moved too suddenly from shade into sun.
Soil
Generally, any quick-draining succulent soil mix will suit it. In pots give the plant an airy growing medium which mainly consists of non organic material such us clay, pumice, lava grit, and only a little peat or leaf-mould.
Temperature
It prefers an optimal temperatures of 60 degrees Fahrenheit – 85 degrees Fahrenheit / 16 degrees Celsius to 29 degrees Celsius.
