Its preferred active growing temperature rages from between 18ºc to 28ºc, although it will tolerate a temperature below freezing. Feeding with weak fertiliser solution should be carried out once a month during the growing season. Cuttings may be taken from sprawling plants, placed in moist sand for a couple for weeks, during which period they will root.
