Jin is a bonsai deadwood technique used on branches or the top of the trunk (the "leader"). A jin is meant to show age, or show that the tree has had a struggle to survive. Jins are created in nature when wind, lightning, or other adversity kills the leader or a branch further down the tree. To create a jin, you need to remove the bark from the branch, leaving the white wood underneath exposed. This white wood will eventually turn brown and create a realistic looking trunk. You can use jin pliers, graving tools and lime sulfur to create and protect your jin. Jin is especially suitable for conifers such as junipers and spruces, but can also be applied to other types of trees if done carefully.
