Ginseng ficus (Ficus retusa) is one variety of this large group of fig trees. Native to Southeast Asia, the ginseng ficus is also called banyan fig,
aiwan ficus, and laurel fig. It is most striking in appearance because it grows thick roots that stay exposed above the surface of the ground. As a bonsai, the effect is of a small tree standing on legs.
The tree grows oval shaped, dark green leaves. The trunk of the ginseng ficus is thick and bulbous, reddish gray and has tiger-like stripes.

Placement : The ficus Bonsai tree is an indoor tree that does not endure frosty conditions. It can be kept outside in the summer as long as temperatures are above 60 °F (15 °C). It requires a lot of light, preferably full sunlight, so be sure not to place it in a shady location. The temperature should be kept relatively constant. Figs can endure low humidity due to their thick, waxy leaves, but they prefer higher humidity and need extremely high humidity to develop aerial roots.
Watering : The Ficus should be watered normally, which means it should be given water generously whenever the soil gets slightly dry. The Bonsai Ficus prefers room temperature soft water and it can tolerate occasional over, or underwatering. We advise daily misting to maintain humidity, but too much misting can create fungal problems. The warmer the placement of the fig during winter the more water it needs.
Fertilizing : Fertilize every two weeks during summer, and every four weeks during winter if the growth doesn't stop. Liquid fertilizer can be used as well as organic fertilizer pellets.
Pruning: Regular pruning is necessary to retain the tree’s shape. Prune back to 2 leaves after 6-8 leaves have grown. Leaf pruning (defoliation) can be used to reduce leaf size, as some Ficus Bonsai species normally grow large leaves. If a considerable thickening of the trunk is desired, the Ficus can be left to grow freely for one or two years.
