Detailed Explanation of Japanese Pagoda Tree Planting Methods and Technical Points

The Japanese pagoda tree, also known as the Chinese scholar tree, white pagoda tree or domestic pagoda tree, is a deciduous tree of the Fabaceae (papilionaceous) family, often used as a street tree and shade tree. The Japanese pagoda tree has high economic and medicinal value and is an excellent landscaping tree species in China.
