Moyogi
The Moyogi style
Informal Upright Style

The Moyogi style in bonsai is characterized by its natural and informal appearance. The trunk may display gentle curves or subtle movements, distinguishing it from the strictly straight trunks of other styles. The branches of the Moyogi bonsai are arranged in an irregular manner, creating a relaxed and organic look.
The leaves or needles of the Moyogi bonsai vary in size and are generally arranged asymmetrically along the branches, further enhancing the tree's natural appearance. The roots of the Moyogi bonsai are well developed and can sometimes be visible at the base of the trunk, adding to its charm.
The Moyogi style aims to replicate the appearance of trees found in nature, with their imperfections and organic movements. It is a style that offers great artistic freedom in the design of bonsais.

Pruning (11 months)
10/19/25
Pruning branches and filling holes. Branches were very messy.
The first 4 branches were properly cleaned, while the rest not. All wholes filled. I cannot clean everything as it would set the tree back for a long time. Some branches pointing inwards are for approach grafting in summer. Maybe with the cuttings as well. Need another three branches on the tree. Third branch needs to come down. Some branches are very fragile with rotten parts inside. Need to let new growth rewigorate. Do not repot this spring. Choose branches and wire the apex. Very messy at the moment. Depending ho good the top is, the 1st branch can be taken off. Manage area around rough transition. Luca says let grow top and better conicity.
Layering (11 months)
10/11/25
Workshop with Luca. Instead of root grafting I will be layering half of the nebary. Big cut, with root gel, paper toilet and fine cut sphagnum to build the nebary. Plus some cleaning of the branches and holes, guy wire for 1st branch.
