Shari is a term used in bonsai to describe the exposed wood on the trunk or branches of a tree. Shari is created when the bark is removed or damaged, exposing the inner wood to the elements. Shari can occur naturally due to weather, insects, animals, or fire, or it can be artificially created by the bonsai artist to enhance the appearance of age and character in the tree. Shari can be made by using tools such as knives, chisels, wire brushes, or jin pliers. Shari should be treated with lime sulfur or other preservatives to prevent rotting and fungal infections. Shari can add interest and beauty to a bonsai, but it should be done with care and respect for the health and balance of the tree.
