New 2012 USDA Hardiness Zone Map Released - Changes Reflect Rising Temperatures Since Last Release

Updated once every several years to a few decades, the USDA has released an interactive GIS-based hardiness zone map for 2012. It is also available in static image form for slower connections. Click image to view interactive link, or use links at the bottom of this post. Gardeners beware ... the climate has changed over the last several decades and the government has reflected these changes with this new hardiness zone map. Most locations throughout the USA have remained the same or been notched up a half zone. A half zone increase may not sound like much - it reflects a 5 degree change - but with first and last frost times so critical, one or two weeks could make a difference between plant life and death. Stuck in-between zones and not sure which zone you belong to? No problem -- just type in your zip code and it will tell you. Currently, the USDA has not printed any posters of this new 2012 map, but you can download state, regional and national maps in a variety of resolutions and print them yourself.
