Chu (16 to 24 Inches, "Two-Hand")

A Chu sized bonsai tree.

The Chu is a category of bonsai trees that ranges from 16 to 24 inches in height. It is considered a medium large size and can accommodate a variety of styles and shapes. The Chu bonsai requires a pot that is proportional to its trunk and foliage, and that has adequate drainage and aeration. The Chu bonsai should be placed in a location that receives partial sun and shade, and that protects it from extreme temperatures and winds. The Chu bonsai needs regular watering, pruning, wiring, and fertilizing to maintain its health and appearance.
