Mochikuzusu

Mochikuzusu is a Japanese term that means degrading in relation to bonsai. It refers to a tree that grows too much, peaks out as bonsai, and becomes unable to maintain its tree shape. Mochikuzusu also means that a bonsai tree's shape will deteriorate after branches or other key elements are broken  . This is a phenomenon that bonsai artists try to avoid by careful pruning and wiring.
