What is the cold tolerance in Zone 7?
Understanding USDA Plant Hardiness Zone 7 Zone 7 features a medium-to-long growing season, commonly frost free from early May to late September. The average minimum winter temperatures in Zone 7 range between 0°F and 10°F. The USDA Plant Hardiness Map divides North America into 11 hardiness zones. Zone 1 is the coldest; zone 11 is the warmest. The USDA Plant Hardiness Zone Map helps gardeners determine which plants are most likely to thrive at a location.The plant hardiness zones are rated 0 through 9, based on climate conditions such as temperature, precipitation and frost duration at locations across Canada.The zone 9 map includes the following states: florida, georgia, south carolina, texas, alabama, louisiana, mississippi, utah, new mexico, arizona, nevada, california, oregon, washington, and hawaii. Every usda hardiness zone is divided into two subsets.Yakutsk has an average annual temperature of −8. C (17. F), winter high temperatures consistently well below −20 °C (−4 °F), and a record low of −64. C (−83. F) has been recorded. As a result, Yakutsk is the coldest major city in the world (although a number of smaller towns in that region are slightly colder). It is a high ridge in Antarctica on the East Antarctic Plateau where temperatures in several hollows can dip below minus 133. Fahrenheit (minus 92° Celsius) on a clear winter night – colder than the previous recorded low temperature.Fairbanks, Alaska Finally, the most extreme cold temps in America deserves the most extreme cold weather jacket you can find. Fairbanks, Alaska, is the coldest city in all of America, with a bone-chilling lowest recorded temperature of -66°F. During January, the average high is 2. F. That’s not a typo.What is the coldest place in the world? It is a high ridge in Antarctica on the East Antarctic Plateau where temperatures in several hollows can dip below minus 133. Fahrenheit (minus 92° Celsius) on a clear winter night – colder than the previous recorded low temperature.
What is the warmest hardiness zone?
Zones get warmer as their numbers rise, with Zone 1 being the coldest and Zone 13 being the warmest. They are divided into increments of 10° Fahrenheit. In Zone 9, winter lows over a 20-year period ranged from 28 to 18°F (–2 to –8°C).
