Bonsai

What bonsai is

Bonsai is a tree or shrub grown in a shallow pot and trained to look like a mature tree in the wild. The word comes from Japanese and means pot planting. A bonsai can begin from a cutting, a seedling, a wild tree called yamadori, or a small specimen of a suitable species. Almost any woody tree or shrub that makes true branches can work. Growers choose kinds with small leaves, needles or aged bark because these suit the compact view. The aim is not to show a whole landscape but the form of one tree or a small group.

Origins and history

Japanese container planting grew out of the Chinese practice of penjing. From the sixth century, embassy staff and Buddhist students travelled to mainland China and brought back ideas and goods, including plants in containers. Scrolls from the medieval period show dwarfed potted trees. A scroll from 1195 is the earliest known to show dwarfed potted trees in Japan. By the fourteenth century people called these trees hachi no ki, meaning the bowl's tree. Zen Buddhist monks helped shape how bonsai looked. They taught that miniature landscapes were a fit accomplishment for people of taste. Japanese artists later made the style simpler, taking away figurines and using plainer, smaller pots. In the nineteenth century the word bonsai came into wider use.

How it is shaped

Shaping starts with source material. The grower chooses a tree, then works to keep it small and to meet bonsai standards. As the tree approaches the size the grower wants, it goes into a display pot, usually one made for bonsai in accepted shapes and proportions. From then on the pot limits its growth. Through the year the grower prunes, reduces roots, repots, defoliates and grafts to direct the tree's form. These methods produce a small tree that echoes the shape of a mature tree. Bonsai is not the same as dwarfing. Dwarfing creates permanent genetic miniatures through breeding or genetic engineering. Bonsai trees are ordinary stock kept small by care.

Tools and techniques

In 1910, growers began to shape trees with wire instead of string, rope and burlap. Zinc-galvanized steel wire came first. Copper wire was costly and used only on trees with real promise. Masakuni I, a toolmaker, worked in the 1920s and 1930s. He helped create the first steel tools designed for shaping bonsai. One was the concave cutter, a branch cutter that leaves a shallow dip on the trunk. If treated well, live tissue and bark fill the dip over time, so the pruning scar is hidden or reduced. Today bonsai tools and display pots are part of the practice.

Today and worldwide

Bonsai is now an international art form and hobby. Japan still hosts large exhibitions with the world's greatest number of specimens and the highest recognized quality. The Kokufu-ten displays, held by invitation for eight days in February, continue. The first World Bonsai Convention took place in Osaka in 1980. The World Bonsai Friendship Federation began in Omiya nine years later, and conventions have since been held in different countries every four years. Books, magazines and public shows helped make bonsai known far beyond Japan. Japanese immigrants and their children set up the earliest bonsai nurseries and clubs in the Americas.

How Bonsai is kept

A grower begins with a cutting, seedling, wild tree or small specimen. The tree is trained to stay small through pruning branches and roots. As it nears the planned size, it is moved into a display pot. After that the pot itself limits growth. Through the year the grower repots, defoliates, wires branches and grafts where needed. The tree is shaped to match bonsai standards, not to show a whole landscape. Viewers take part by looking at the tree, and the grower takes part through patient, repeated care. Exhibitions let owners and visitors see and rank trees.

When and where

Bonsai is a year-round practice, not a dated festival. Its main public moments are exhibitions. The Kokufu-ten show in Tokyo runs for eight days each February. World Bonsai Conventions have been held every four years since 1989, at different locations.

Bonsai belongs to Japan and is strongest there. Tokyo is its main centre, home to major exhibitions and the Imperial Palace collection. Kyoto held a yearly show of dwarf potted pines in the Tenmei era. Osaka hosted the first World Bonsai Convention in 1980, and Omiya launched the World Bonsai Friendship Federation. Today growers keep bonsai in many countries, including the United States, Germany, China, Korea, Vietnam and Australia.

What Bonsai means

For growers, bonsai is a quiet practice. The viewer is meant to contemplate the tree, while the grower finds pleasure in effort and ingenuity. A bonsai is not grown for food or medicine. The tree stands for patience and care, and for a small, living echo of a mature tree in the wild. In Japan, Zen Buddhist monks helped give the art this reflective character. Many people also see bonsai as a link to nature inside a home or garden.
