Well, since you live in Florida then maybe it doesn't matter with the pot sizes. But for people who live in PA or NY...we can only plant them in a size or two larger than their rootball. If the tree is in a pot triple it's rootball size then it's more likely to get root rot and it's not healthy. I made that mistake when I first started planting these tropical trees. I planted all my trees in a much larger size pot than their rootball and a few ended up dying because the water stayed in the pot longer causing root rot or disease.

Sometime you can just eyeball the pot and get one two-3 inches larger. Also, pick the pot size depending on the growth rate of the tree. I know star apple grow very fast so I put it in a pot 4 times it's rootball. The jackfruit, I have to put it in a smaller pot because it's more sensitive with wet soil.

Good luck.
