It is a shock to many people that yes, apples can be grown in a tropical climate, and have been grown by the millions for many years.
This goes against the conventional wisdom that apples need between 800-1,000 hours below 7° C. (45° F.) in order to break dormancy and set fruit. But experience has shown that using tropic apple culture methods can fool the tree into thinking that it's chilling-hour needs- whatever they may be- have been satisfied and it will then blossom and fruit. You still must be choosy about which varieties to plant, and the tree will act much different than in a cold climate, but the end result is crisp, juicy, tasty apples.
