Creating Jin, Uro and Shari
Creating deadwood on a Bonsai, such as Jin, Uro, or Shari, can significantly enhance the character of the tree. A "Jin" refers to a stripped portion of a branch, "Shari" denotes a section of trunk without bark, and "Uro" describes a hollow, irregularly shaped wound within the trunk. In the wild, deadwood forms when a tree endures lightning strikes, suffers through extended droughts, or when branches break due to the stress from ice, wind, or the weight of snow. The wood then perishes and is gradually bleached by intense sunlight.
This technique is predominantly applied to evergreen trees. Utilizing Jin or Shari on deciduous trees often results in an unrealistic appearance, as deadwood on these types of trees tends to decay over time. However, it is common to observe Uro on deciduous trees in natural settings.
When to Apply This Technique?
Great trunk movement, and the deadwood (Shari) is absolutely stunning..
The deadwood on this trunk (both Jin and Shari) looks very impressive.
How to Create Deadwood on Bonsai Trees
Creating a natural-looking Jin or Shari entails experience; it’s advisable to practice before attempting the technique on valuable trees. Utilizing the correct tools is crucial; Jin pliers, carving tools, and lime sulfur, which are available at most Bonsai shops, are recommended.
Creating a Jin on Bonsai To initiate a Jin
Remove the bark from the branch to expose only the hardwood. Use Jin pliers to peel away slivers of wood, trimming them at the base of the desired Jin. After shaping the Jin, smooth out any sharp edges with a concave cutter or sandpaper. To prevent decay and enhance the appearance, apply lime sulfur to the Jin, allowing it to dry overnight. Detailed instructions are provided below.
Creating a Shari on Bonsai
Selecting an appropriate location for a Shari is critical; it must be aesthetically pleasing and not interfere with the tree's nutrient pathways. Start by outlining the Shari on the trunk with chalk. Progress gradually: begin with a narrow strip of bark and widen incrementally over months or years. Use a sharp knife and Jin pliers to strip the bark, and carve out the groove with a concave cutter or carving tools. Finally, apply lime sulfur to protect against infections and to whiten the Shari.
