Kirikomi is a term used in bonsai to refer to the act of cutting or severing a branch. It is one of the ways to shape a tree and is similar to sentei, which means trimming of a tree. Kirikomi is often done to reduce the size of a branch, create a more compact silhouette, or remove unwanted growth. Kirikomi can be done on any type of bonsai, but it is especially important for deciduous trees that tend to produce long and thin branches. Kirikomi should be done with sharp and clean tools to avoid damaging the tree or causing infections. Kirikomi can also be combined with other techniques such as wiring, pruning, or defoliation to achieve the desired shape and style of the bonsai.
