Your Place to Bonsai!

The bonsai form from the root to the top with the gradual tune outline in the front, back, left and right trying to express the tree that grows up while bending by the wind action between the long tract of years.

Key points to make this shape

1. wire the trunk and bend it to the front, back, right and left.

2. better if it has a twisted part on the trunk.

3. the top of the tree is covered with the dense foliage.

4. making a jin on the remaining of a cut branch is recommended

5. it's not recommended to style this shape with a Hump looking trunk (see picture below) in the front even though the form itself bends in many directions

6. since there are usually many curves and twists, the branches are used as a method of taking the balance in this effect. read more about branch rules

7. one of the most unwanted shape for informal upright is the trunk that stands a little bit from the bottom and then starts bending to whichever direction

8. the bottom of the trunk must be bending in the same direction where the trunk is bending to

A is called "hatomune"  (looks like a hump) which is considered to be a bad trunk shape, when it's seen in the front side of the bonsai the front side should be changed.

B is just a regular shape of a curving trunk.

In example 1, the space A has the main trunk with too many parts that are just curving and growing to the top for the informal upright style bonsai. And this makes less impression of good informal upright.

The space B is the trunk growing too straight from the bottom for this shape. It looks better if the trunk is slanting slightly to the left at the bottom in this case. ( the shape in this picture is called "coiled style" (bankan) similar to moyohgi but has more curves that look like a coil)

In example 2, the space A is called futokoro - often used to express the good expression of informal upright style.

A better looking trunk for slanting or curving shape should grow less straight at the bottom. It's better if the nebari (roots that appears at the surface) is growing to the opposite direction of the trunk growing to. read more about nebari surface root rules.
