What is a Growing Zone?

Growing zones are often known as Hardiness Zones. They are geographical areas that have been divided up by climate. These zones are used to determine where different plants will grow best. The USDA Plant Hardiness Zone Map has 13 zones that divide the United States and Canada based on their average annual minimum winter temperature. Plant hardiness is measured by its survival rate in cold winter temperatures.

When looking at each zone, the zone that is next to it on the map is, on average, 10 degrees warmer or colder in the winter. Zone 1 is known to be the coldest, while  Zone 13 is the hottest. Things like terrain, bodies of water, and urban heat island effects may have an impact on the  result for which growing zone an area is located in. 

You can find Caldwell, Idaho located in both Hardiness Zones 6b and 7a.
