White sapote is native to Central America north to Mexico. It is found in subtropical deciduous woodlands and low forests. It is also found in Dryish highland forests at elevations of 600 - 1,000 meters.

Fast growing. Regular (4 - 6 times per year) light pruning is required for the more vigorous types during the first two years to obtain adequate branching without delaying fruiting too much.
