context_page_description: Deadwood bonsai techniques are methods in the Japanese art of bonsai that create, shape, and preserve dead wood on a living bonsai tree. They enhance the illusion of age and the portrayal of austerity that mark a successful bonsai.
context_section_description: While jin appear natural on coniferous bonsai, they do not look as appropriate on most deciduous and broadleaf species. In these species, dead branches generally rot and fall off the tree. A small indentation is left where the branch used to be, and new wood grows around it forming a small hollow. Bonsai gardeners replicate this hollow as a uro by making a small, irregularly-shaped wound in the trunk . For example, when removing a branch from a deciduous or broadleaf species, bonsai growers often make a uro to avoid having an ugly wound healing slowly and scarring without control.
