THIS JUST IN...... THINGS ARE HEATING UP!
A revised version of the USDA Hardiness Zone map will be released later this year according to recent reports. The color-coded map, found on the backs of seed packets and in garden magazines and on websites, shows the average annual minimum temperatures for the USA. Across the country, those average minimal temperatures have been slowly rising. For an interesting visual on how the zones and general warming patterns have changed between 1990 and 2006, visit www.arborday.org/media/mapchanges.cfm.
