Hoozue:Indigenous Japanese Technique for Preservation of the Legacy Katsura Tree at Dumbarton Oaks
The katsura tree at Dumbarton Oaks is among the oldest of the species in North America and pre-dates the design of the garden.Japanese master gardener Kurato Fujimoto was commissioned to inspect and lead the construction and installation of a series of branch supports,known as"hoozue"in Japan,to rejuvenate this venerable tree that was in decline.The assessment of the tree included the inspection of the branch structure with a projection toward post-installation growth over the next several decades.Materials such as rope,bark fabric,nails(kasugai),and the wooden hoozue themselves were fabricated and installed with indigenous knowledge and experience,which were described in the text and drawings and documented in a series of photographic sequences.This article narrates the process of this preservation work,demonstrating the significance of this indigenous Japanese technique.
