The trick to creating a multiple fruit-bearing tree is to graft several compatible varieties or species onto the same rootstock. This is easiest when using bud grafting, since the rootstock experiences less shock. characteristics is determined by the species of fruit trees you wish to graft together. Generally speaking, they need to be very closely related for the graft to take successfully.
