Breadfruit has a wide range of adaptability to various environmental conditions within the tropics. It grows best in equatorial lowlands below 600-650 meters (1,969-2,133 feet) but is found at elevations up to 1,550 meters (5,085 feet). It flourishes between 21-32° C (70°-90° F) and may not yield well where the temperature exceeds 40° (104° F) for long periods of time or drops below 5° C (41° F). The latitudinal limits are approximately 17° N and S; maritime climates extend that range to the Tropic of Cancer and Capricorn. Optimum annual rainfall/irrigation is 1,500-3,000 millimeters (59-118 inches), but trees yield regularly on Pacific atolls that receive 1000 millimeters (39 inches) of rainfall. Breadfruit prefers deep, fertile, well-drained soils for a more aggressive growth, but many varieties have adapted to the shallow sandy soils of coral atolls in the Pacific. In Hawaii, breadfruit grows well on rocky, volcanic soils that drain readily.
Areas within the following countries are suitable for the cultivation of breadfruit based exclusively on temperature and rainfall. Many countries not listed are likely to have suitable environs for the cultivation of breadfruit with a reliable source of irrigation. Because of the previous limited access to large numbers of trees, research in every possible climate has yet to be conducted. The potential for cultivation of this useful plant in areas outside the typical range is quite high and more research is underway to test the limits of the plant relative to environmental conditions.
