The Ficus retusa, also known in the "Ginseng" variety, is the most popular type of Ficus bonsai, and is very much appreciated for creating elegant green corners inside an apartment. There are more hypotheses that could explain the name Ginseng: the term derives from the Chinese "Jen-Shen", whose meaning is "man's plant"; its roots have a silhouette that resembles that of a human figure. A second probable explanation is that the shape of the roots remembers much that of the herbaceous plant used in herbalist, but with which it has no kinship. The trunk is whitish, while the foliage has a beautiful shade of intense green and each leaf is oval and pointed. The most striking aspect of this plant is the spectacular roots that create a fascinating tangle on the ground, which is why it is one of the bonsai that best suits the Japanese style "Neagari", or roots exposed. In addition, other aerial roots leave branches, which, after reaching the ground, form further trunks. Ficus Ginseng is particularly suitable for those who want to get closer to the world of bonsai, its flatbed features and longevity make it ideal for cultivating this passion.
Exposure and brightness: It is a bonsai that can live peacefully inside in abundant light conditions, better if in the South, although it can be kept outside even during the summer months.
Temperature: Being its tropical origin, it does not suffer at high temperatures; it does not tolerate much temperature below 10 ° C.
Soil type: It is a fresh, well-permeable, quite drained soil: a mix of universal soil rich in mineral salts and Akadama is ideal.
Irrigation: Always keep the soil slightly moist, with fresh water at room temperature, then watering the plant whenever the soil is dry on the surface.
Fertilization: Every two weeks during the summer, every four during the winter, with nitrogen fertilizers poor.
Pruning and replanting: Ficus pruning must be done in the spring, before the bonsai has resumed its vegetative cycle, and in autumn, which will be followed by defoliation interventions. The withdrawal should be carried out every 3-4 years in the spring.
N.B. The specifications described above may vary depending on the climate of the area where the plant is placed and the season.
