Informal Upright Style
In their natural habitat, these trees twist or change their angle past the breezes, shade, additional trees, buildings, or in the direction of sunlight. For an informal upright bonsai, its trunk needs to be a bit bent to the left or right, but this should never be up to the observer. This is true for all kinds of bonsai. The branches and trunk should not be angled at the observer while the bonsai is being surveyed from the front.
For this approach, test out a Trident maple, Japanese maple or almost any kind of ornamental or conifer tree you can think of. You will notice a major effect with any flowering trees or pomegranates. An informal upright bonsai pretty much employs the same standards as the formal upright bonsai, except for the fact that it is informal. This type still necessitates an elongated trunk, although the angle of the trunk and branch placement are more informal and more similar to the way a tree appears when subjected to the elements at a young stage in its life. Generally, the trunk will develop an unprecedented arc or sequence of coils, and therefore the branches are placed in such a way that evens out this effect.
Just as it is with a formal upright, the tree’s crown is mostly filled with greenery and, in spite of the informal trunk, it is usually found right over the base of the tree. This is a quality of the informal upright form, and if it is not conducted in this way, the tree will be at a slant. Jin, which is the carved remnants of dead (or undesired) branches made to appear like dead and rotting tree limbs, is additionally more appealing and efficient for the informal upright style.
