I have in ground what I believe to be either a Mamey Zapote or a Green Zapote. I'll know for sure hopefully in a year since it is holding quite a few fruit. I also have in a pot an Abiu and I was thinking of putting a scion of it onto the Zapote as a sort of insurance for the Abiu since I haven't been able to plant it yet. Are these species compatible for grafting?
I read an old study about grafting Mamey Zapote to Canistel rootstock and it said all the scions died but it concluded that canistel was a good candidate for grafting Mamey Zapote, which is at least confusing so I thought I'd ask here for anyone who's had experience and success
