I have several dwarf peach/nectarines. some ornamental types and 2 fruiting types. this year some suckers arose from the rootstocks so i took the opportunity to graft/bud a peach variety given to me by a friend. The hope was to create another dwarf plant which i could separate off later. The newly grafted peach is growing well but appears not to be dwarfed by the rootstock. So, the question is : What went wrong?! Why did the newly grafted peach escape the effects of the dwarfing rootstock?
