Ficus retusa, which is the specific name of the plant, is also commonly called Ficus ginseng because of the gnarled aerial roots, which at first glance recall the ginseng roots used in herbal medicine. This bonsai is characterized by an enlarged and gnarled stem. The leaves are broad, oval, shiny and of a bright green color. 

TREATMENT: Ficus ginseng is a houseplant, which hardly tolerates the winter climate with freezing rains: the suitable temperature is that of the home, which on average should be between 18-20 ° C at night and during the day. This bonsai needs a bright area, preferably near a stained glass window. Be careful to avoid placing it in areas where there are drafts, which could dull the leaves and cause them to fall. 
Ginseng needs regular watering, but taking care that there is no stagnation of water. 
In order to make this plant grow healthy it is necessary to feed it on average once or twice a month in spring / summer. Drastic pruning is not required, but light pruning - which consists in cutting dry branches to give the plant a new aesthetic - is useful in spring, when the new vegetative period begins.
