This lecture is from the bonsai school “Bonsai Journey.” We explain how to maintain a roughly 200-year-old collected juniper for the Kokufu Bonsai Exhibition. The process includes cleaning the Jin and Shari deadwood and applying lime sulfur. We share practical tips for this May season work. Learn high-pressure spray gun use for removing water stains. Discover how to avoid damaging the tree’s water absorption. We cover cleaning decayed areas and lime sulfur mixing ratios. Understand pre-application dampening and how many treatments are needed to achieve a natural white appearance for the exhibition.
