Growers need to know what minimum temperatures to expect in order to know when to safely plant their crops. For the first time since 1990, the U.S. Dep’t of Agriculture has revamped their map which details the various growing zones for plant hardiness in the U.S. Now you can go to a GPS-based source to find out which plants will do well in your own area’s climate.
Plant hardiness zones are determined by the lowest average temperatures in a band across the region. This new map was able to shift zones slightly to reflect the approximately 5-degree temperature increase in general. Also, 2 more temperature bands were added to the map, allowing for it to document each band as approximately 10-degree temperature changes. You can read a SUMMARY HERE or you can go directly to the NEW PLANT HARDINESS MAP.
