Hey Brad, we can grow white sapote here, so i'm sure you can grow them there. It's a widely adaptable tree. Though i notice they do a lot better here in Kona, dry side of the island. It's quite a bit hotter in Kona than here, so temperature doesn't seem to be the problem. I think in higher rainfall areas they are more prone to disease: molds, fungus, etc. So it's all a question of how much you like the fruit and whether you're willing to make the extra effort to push the boundaries? Mine are fruiting right now, thanks for reminding me i gotta go out and pick some.
