            New trees can be raised from seed.  This tree is dioecious and it is not possible to determine the sex of trees visually at the time of planting.  So to be sure about the sex of tree at the time of planting, it is better to multiply  plants by grafting as the budwood taken from a female tree, will certainly grow into a female tree.

            Bincau has also been tried at some places as a rootstock for mangosteen.
