I think after this last Champagne flush hardens..I think will plant it. It will be just right size and the rootball looks solid.
JF,I dunno about mediocre. Compared to market Mangoes, Baileys was much better. Still,If I get the chance to make a side trunk or large branch something better,I will listen. Why not?
I would usually say Baileys is cold hardier yada yada. But now,I'm in with the group that says..protect any young tree from freezing is the best idea. As far as pests disease...nothing so far.
I get the feeling Mango trees in California are not really any problems short of root rot. And that's usually just bad siting. Plant where it drains great in winter.
