2012 USDA Plant Hardiness zone map. Edit: Cool map. You can zoom in using the interactive map; also type in a zip code to get the zone.

This is the map they've been working on for like 15 years, isn't it? It apparently incorporates all the new data on climate change and microclimates.

I was just pretty shocked to learn that my zone is now 7B -- after all these years of being a "6". Is there really anything that I need to change about what I've been doing? I've always not planted until Memorial Day or just a little before. I used to use row covers and cloches to try to get a jump on the season, but stopped that a number of years ago since I saw that my production was overall better by being more patient and planting when I do. Any advice would be welcome.
Thanks. |

I'd say unless there is a problem, keep doing what you are doing. A higher zone number just means it doesn't get quite as cold in the winter.
The map is only based on average annual extreme minimum temperature. Meaning from 1976-2005 what was the absolute coldest it got on the coldest night each year, those 30 temperatures are added up and divided by 30 to get the average, this was done for each weather station they have, assigning colors to temperature ranges, and the map was computed to fill in the space between the stations based on terrain, slope, closed valleys, trees, etc. It's real purpose is finding what perennial plants and trees should survive the winter in an area. Basing a planting date off the map isn't very good, because some places have the same color on the map, but warm up in the spring at different rates. |

Great information....Thanks. I was also looking for average first and last frost dates around the country. Does anyone know where I can find that link?
Thanks again! |

I found mine by putting first and last frost date with my zip code in google. I came up with three dates for my last frost date. One I know was wrong for me due to my micro climate. A few blocks from me might be correct. |
