Growing in well-drained soil, Tolerates considerable frost a low as – 4° C (or less) and dry conditions due to its tuberous roots. This species is slow growing and after some years, the roots can be raised for effect, creating a beautiful succulent bonsai. This plants in the first years are usually grown in black nursery containers but if you have a mature specimen with a nice caudex, a bonsai pot or dish seems to make the plant a little more special and helps display the plant well.
Use: Roots of Trichodiadema species have been used in the past for speeding the fermentation of bread, beer, etc. It is presumed they contain either yeast or sugars which increase the rate of fermentation.
Propagation: Seeds, it can be also reproduced by cuttings.
