The effects of trunk wrapping and leaf removal at the transplanting of Prunus yedoensis Matsum. in vegetable season are experimentally studied. Transplanting were held in June of rainy season and in August of mid summer, and in each month trunk wrapping, leaf removal,both treatments of two, and control sections were set in the experimental field, and the growth after planting were analyzed until November. Five individual trees of three years after grafting were planted in each treatment, and their height were around three meters. Leaf removal sections show significantly lesser growth including root system than trunk wrapping and control sections in June transplanting. Contrarily in August transplanting leaf removal and trunk wrapping are effective to keep alive, but tree form is changed compared with the ordinal form and root growth becomes also poor.
