I have heard this is best done with winter banana apple tree which I dont have. Has anyone ever successfully gotten a pear scion to fruit on an apple tree?
John, that is definitely wrong. They are of the same family, rosascea, but are not all compatible. No prunus is compatible with any pyrus or malus for example.
I have grafted pear onto apple and it grew in a super-stunted and very confused way (flowering in fall for example). It did stay alive several seasons but I got sick of looking at the ugly thing and took it out.
