Motoboso

Motoboso is a Japanese term that refers to the slimness of the knags or knots of the trunks and branches of a tree. In bonsai, motoboso is considered undesirable because it gives a sense of instability and weakness to the tree. Bonsai artists prefer thicker and stronger knags that show age and character. Motoboso is often seen in young or immature trees that have not developed enough girth or taper.
