In this episode, Mario takes on one of the most challenging and subtle topics in bonsai art: shohin composition. Using trees presented at the VI UBE Exhibition, he explains how individual shohin trees interact with each other, how balance, rhythm, and hierarchy are created, and why composition goes far beyond simply placing trees together. This is a complex subject that cannot be exhausted in a single episode. Mario opens the discussion, points out common mistakes, and lays the foundation for a deeper understanding that will be developed further in future episodes.
