Carpinus Betulus Bonsai
Carpinus Betulus is a widespread tree in Western Europe due to its ability to withstand the most adverse conditions, such as urban environments characterized by pollution. In addition, it adapts to different styles, grows fast, resists pruning and this is a very used kind of bonsai. Its development often sees the formation of several trunks, the foliage assumes an oval shape when it manages to expand without obstacles. The oldest trunks are distinguished by the silver-colored bark and in some specimens, especially the inclined ones, longitudinal openings are formed.
Hornbeam prefers an environment sheltered from the sun during the warmer months, while during the rest of the year it needs full sun but paying attention to the temperature, as the excessive heat could burn the roots.
This plant is suitable for different types of soil, but often a compound consisting of akadama, tufted earth, lava lapilli, coarse sand is used. The soil must be moist and therefore the watering must be adjusted accordingly. In general, the plant needs abundant water in Summer compared to the cooler months. As for fertilization, however, this must be constant every two weeks, while after the birth of the leaves in spring, fertilization must be done every week.
Hornbeam needs repotting every two years during spring and when roots are so thick that they fill the pot. Also essential is the pruning of the branches, which has to be done in spring, a short time before germination, in order to promote the growth speed.
