The zones are further divided into sub-climates, denoted by the letters "a" and "b," which represent a 5°F difference in temperature.

Explanation of How Gardening Zones are Determined

Gardening zones are determined by the average annual extreme minimum temperature of a region. This temperature is calculated by taking the average of the lowest temperature recorded over a 30-year period. The temperature is then used to determine the gardening zone, with colder temperatures corresponding to lower zone numbers.
