Rationale and Application of Deadwood Techniques
– Deadwood techniques are used for practical and aesthetic reasons.
– Deadwood can be present on aged trees or bonsai under cultivation.
– Removing deadwood can damage the tree’s shape or the illusion of age.
– Deadwood must be chemically treated for preservation and coloration.
– Deadwood needs to be shaped to fit the aesthetic plan for the bonsai.
Deadwood Techniques
– Deadwood techniques are used to enhance the illusion of age in bonsai.
– Deadwood can be an aesthetic choice to hide defects or modify the shape.
– Deadwood techniques are more commonly applied to conifers.
– Deciduous trees tend to shed dead branches and heal over the wound.
– The driftwood style is generally restricted to conifers.
Jin
– Jin is a deadwood technique used on branches or the trunk.
– Jins show age or indicate a struggle for survival.
– Bark is completely removed to form a jin.
– Top jins create a shorter and more tapered bonsai, enhancing the illusion of age.
– Jins on branches can remove unwanted branches and increase the illusion of age.
Uro
– Uro is a hollow created in the trunk of deciduous or broadleaf bonsai.
– Uro replicates the natural hollow left after a dead branch falls off.
– It is used to avoid ugly wounds and slow healing.
– Uro is made by making a small, irregularly-shaped wound in the trunk.
– Uro is more appropriate for deciduous and broadleaf species.
Shari and Driftwood Styles
– Shari is deadwood on the main trunk of the bonsai.
– Shari usually runs vertically on or near the front of the trunk.
– Shari occurs naturally or can be created by carving the bark.
– Driftwood style is when a large portion of the tree has a weathered look.
– Driftwood-style trees often do not follow conventional bonsai styles. Source URL:https://en.wikipedia.org/wiki/Deadwood_bonsai_techniques
