seedlings dislike strong
dry conditions and need to be
repotted frequently. Eventually, as they become mature, they attain a
maximum size of 8-10 cm (20) cm. However, old plants become
senile and have
a tendency to succumb to
disease and a weak
root system. At this

suddenly. So, after they reach 10 cm in diameter grow them slowly, and
adopt a new repotting period, using intervals of every 2 - 3 years.
Additionally grow them under drier conditions or with stronger sunlight.
