Sankan Style: The Three-Trunk Bonsai
Definition and Origins
The Sankan style, also known as the "three-trunk style," is a specific form of bonsai that features three distinct trunks emerging from a single root base or very close to each other in the soil. This style evokes the image of a small group of closely related trees, creating a natural and harmonious scene.
Distinctive Characteristics
- Three Trunks of Varying Heights: In the Sankan style, the three trunks generally vary in height, with one larger main trunk and two smaller secondary trunks, creating an interesting visual dynamic.
- Common Root Base or Proximity: The three trunks share a common root base or emerge from very close points in the soil, emphasizing their interconnectedness.
- Natural Balance and Harmony: The arrangement of the trunks aims to create a sense of harmony and natural balance, reflecting the appearance of small groups of trees in nature.
- Cohesive Branching: The branching of each trunk contributes to the overall canopy, creating a cohesive and integrated whole.
- Appropriate Pot: The pot for a Sankan bonsai is chosen to complement the composition of the three trunks, often wide enough to accommodate their arrangement.
Species Selection
Species suited to the Sankan style are those that can naturally produce multiple trunks or can be encouraged to do so. Maples, pines, and azaleas are often used for this style.
Maintenance and Cultivation Techniques
- Pruning and Pinching: Pruning is essential to maintain the visual balance between the three trunks and to encourage dense and uniform branching.
- Wiring: Wiring may be necessary to direct the branches of the trunks in order to maintain the harmony and balance of the composition.
- Repotting and Substrate: A well-draining substrate is crucial, as are regular repottings to maintain the health of the common root base.
Conclusion
The Sankan style offers a miniature and artistic interpretation of a small group of trees, capturing the essence of coexistence and harmony in nature. This style is appreciated for its balance and representation of a natural community in miniature.
