Before grafting, a mature and robust branch should be cut from a mother plant that has grown for more than one year, using magnolia flowers as rootstocks, cutting a grafting interface on the rootstock, and also cutting a grafting interface with the same width as the rootstock on the cut branches. Pay attention to disinfecting the wounds of rootstocks and branches to avoid infection. Then plug them together, align the two interfaces, and wrap the grafted wound with a special film for grafting.
