Sokan Style: The Double-Trunk Bonsai

Definition and Origins

The Sokan style, also known as the "double-trunk style," is a form of bonsai characterized by two trunks emerging from the same root base or very close to each other in the soil. This style reflects the natural aspect of trees which, in nature, may develop two main trunks from a single root system, often in response to environmental conditions or damage at a young age.

Distinctive Characteristics
  1. Two Trunks of Different Sizes: The Sokan style features two distinct trunks, one usually larger and thicker (the main trunk) and the other smaller (the secondary trunk).
  2. Common Root Base: The two trunks share a common root base or emerge from very close points in the soil, creating an impression of a close relationship.
  3. Balance and Harmony: Although of different sizes, the trunks are arranged to create a balanced and harmonious composition, reflecting natural aesthetics.
  4. Branching and Foliage: Each trunk develops its own structure of branches and foliage, contributing to the overall canopy of the tree.
  5. Pot and Presentation: The pot chosen for a Sokan bonsai is often wide enough to accommodate both trunks and enhance the natural aspect of the composition.
Species Selection

Species capable of developing multiple trunks from a common base are ideal for the Sokan style. Maples, pines, and azaleas are popular choices for this style.

Maintenance and Cultivation Techniques
  • Pruning and Pinching: Pruning is crucial to maintain the shape and balance of the two trunks, as well as to encourage proper branching.
  • Wiring: Wiring may be necessary to direct branches and help form the structure of each trunk.
  • Repotting and Substrate: A well-draining substrate is important for root health. Regular repotting is necessary to maintain the tree's vigor.
Conclusion

The Sokan style offers a natural and artistic representation of coexistence and interdependence. It symbolizes union and strength, capturing the essence of two living beings sharing a common base and growing together in harmony.
