1. Vertical Pruning: The technique involves pruning trees so that new shoots grow vertically from the main trunk, creating a structure similar to a giant bonsai but with practical purposes for timber production. 2. Timber Production: The vertical shoots are cultivated for about 20 years before being harvested. This method allows for the production of straight, uniform, and high-quality timber, ideal for traditional house construction and furniture making. 3. Sustainability: Daisugi is a sustainable method because it allows for timber harvesting without completely cutting down the tree. After harvesting the shoots, new shoots can grow, ensuring a continuous source of wood. 4. Aesthetics and Culture: This technique is not only functional but also has an aesthetic and cultural significance. Trees pruned with the Daisugi technique become true natural works of art, similar to large bonsai, reflecting the harmony between nature and human intervention. Daisugi Pruning Procedure 1. Tree Selection: High-quality Japanese cedar trees are selected, which have good growth and structure. 2. Branch Pruning: The lateral branches are pruned, leaving only the vertical shoots. This must be done precisely to ensure that the new shoots grow straight and robust. 3. Care and Maintenance: The trees require constant care, including the removal of unwanted shoots and protection against diseases and pests. 4. Harvesting: After about 20 years, the shoots are harvested. The main tree continues to live and can produce new shoots for future harvests.

The Daisugi technique is a traditional Japanese method of tree pruning, specifically used for timber production. Originating during the Muromachi period (1336-1573), this technique is particularly associated with the cultivation of Japanese cedars (Cryptomeria japonica) in the Kitayama region, near Kyoto. Characteristics of the Daisugi Technique

Benefits of Daisugi - Land Use Efficiency: It allows for a large amount of wood to be obtained from a small area. - Timber Quality: The wood obtained is of high quality, straight and free of knots, perfect for carpentry. - Forest Conservation: It reduces the need to cut down entire trees, contributing to forest conservation. Daisugi represents a perfect balance between human need for resources and respect for nature, embodying the principles of sustainability and harmony that are deeply rooted in Japanese culture.
