The USDA just updated it's Plant Hardiness Zone Map. Click here to go to the map. It is more sophisticated and accurate than any other previously developed. Several areas underwent a zone change, including my little corner of the Pocono Mountains, PA. We went from 5b to 6a. The new map has links to view states divided into counties, and even a handy zipcode search box. This took a long time to be ready, but the interactive component by zip code was worth waiting for.
The USDA describes the 2012 USDA Plant Hardiness Zone Map as the standard by which gardeners and growers can determine which plants are most likely to thrive at a location. The map is based on the average annual minimum winter temperature, divided into 10-degree F zones.
The Washington Post produced an interactive map with a fancy slider in the middle so you can compare the old map with the new. Click here for the link. This is really interesting not only for gardeners, but for those collecting examples of the impact of climate change on all of us.
In other news the National Wildlife Federation has decided to end its partnership with Scott's. Yoo...hoo! Maybe the scathing letter I wrote them made a difference! I'd like to think so. I wont be taking down my sign after all.
