What are USDA Hardiness Zones?
USDA Hardiness Zones are a system developed by the United States Department of Agriculture (USDA) to classify areas based on their average annual minimum temperature. This system divides the United States and Canada into 13 zones, with each zone having a 10-degree Fahrenheit difference in temperature from the adjacent zones. These zones are further divided into subzones, making a total of 26 zones.
Definition of USDA Hardiness Zones
USDA Hardiness Zones are geographical areas that are classified based on their average annual minimum temperature. These zones help gardeners and farmers determine which plants are most likely to thrive in their specific climate.
Purpose of USDA Hardiness Zones
The main purpose of USDA Hardiness Zones is to help gardeners and farmers select plants that are most likely to survive and thrive in their specific climate. This system also helps in predicting which plants are more susceptible to cold damage and which ones can withstand harsh weather conditions.

How are USDA Hardiness Zones determined?
The USDA Hardiness Zones are determined by using the average annual minimum temperature data collected over a 30-year period. This data is then used to create a map that divides the United States and Canada into different zones based on their temperature ranges.
Changes to USDA Hardiness Zones over the years
Due to climate change, the USDA Hardiness Zones have been updated several times since its inception in 1960. The most recent update was in 2012, which showed an overall increase in temperature across the United States and Canada. This means that some zones have shifted, and some new zones have been added.
