Do not place three or more trees on the same line. The trunks should vary in thickness and height. The number of trees in a smaller group cultivation should be uneven.

A popular style of creative bonsai. It uses shallow and wide pots, and plants several trunks close together. The expression of the individual tree changes greatly depending on its arrangement, such as the strength and spacing of the trunks.
In nature, trees are forced into all kinds of shapes under the influences of weather, wind and placement. Consequently, bonsai trees can have many shapes and sizes and, depending on their way of growing, they are grouped into various styles and shapes.
The Japanese devised the coded styles less than a hundred years ago. These styles make it possible to classify the trees according to the shape of their trunks, their branches, their roots. To know the styles is an obligatory base for amateurs. Though nowadays, without renouncing these styles, more importance is attached to the artistic values of movement, harmony and the coherence of the tree.
