Understanding your growing zone is very important because it is a measure of the lowest temperature that a plant can survive, helping you to decide what plants would grow best in your particular climate. Since Kahului is in growing zone 12b this means that plants there can survive temperatures as low as 10 to 15 degrees Fahrenheit.
