Hawaii Planting Zones & Schedule

Thanks to its tropical climate, Hawaii spans USDA Zones 8b through 13a, with temperature and elevation creating distinct microclimates across the islands. Higher elevations on Maui, Kaua‘i, and the Big Island fall between Zones 8b and 10b, where cooler conditions support crops like lettuce, cabbage, and root vegetables.

The lower coastal and island regions lie within Zones 11 to 13, providing year-round warmth ideal for tropical fruits, herbs, and vegetables such as pineapples, peppers, and papayas.
