Daisugi – Ancient Japanese sustainable forestry technique allows for lumber production without cutting down trees

Originally invented by the people of the region of Kitayama, the method was used to solve the problem of shortage of seedlings. Daisugi is a Japanese forestry technique where specially planted cedar trees are pruned heavily. like giant bonsai, to produce “shoots” that become perfectly uniform, straight and completely knot free lumber. The shoots are carefully and gently pruned by hand every two years leaving only the top boughs, allowing them to grow straight. Harvesting takes 20 years and old “tree stock” can grow up to a hundred shoots at a time.
