Thanks for the suggestions.
@FrankDrebinOfFruits - I have some Jabos in the pots, they don't seem to like my soil.
@sildanani - I Just cut down my inga which opened up this spot. Guava would be great but i don't think the city would like the sight of bags all over the tree.
@TheDom - I actually cut a palm down and left a 10 foot stump, got American Beauty, Haliey's Comet and Natural Mystic growing up it.
I think I'm going to do a SE Asian mango cocktail tree as a fun experiment.
Keow Savoy, Brahm Kai Meu, Pim Seng Mun, Chocanan, Lemon Meringue etc.
As many as I can find with roughly the same vigor I'll add on.
I'll try to document it and post updates.
Please let me know if there are any other varieties I'm missing.
