盆栽

1. Origins, structure, and basic meaning

• Structure: 盆栽 (ぼんさい) combines tray or pot 盆 and cultivation 栽 to denote bonsai.
• Basic usage: It involves raising a tree in a container and deliberately trimming its branches and form.

2. Common pitfalls and similar expressions

• Cultivated miniature, not merely a small tree
  • A 盆栽 is shaped and maintained through horticultural practice rather than simply being a naturally short tree.
