Answer #1 · John Heider's Answer · HI C-Since 1990 the USDA Plant Hardiness Zones have changed a couple of times around the Atlanta area because of warming trends in your area. Most of the counties in that area fall into Zone 8A and north of Atlanta 7B. At the very top and to the right of any page in Gardenality you will see Hardiness Zones. Click on this to get a good idea of what Zone you are in.

The USDA has a good site that will pin down your exact zone by Zip Code and will give you a nice close up map of Georgia for you to see your area quite clearly. I noted the link to this site below. Just click on this link to go directly to the site. Hope this helps you.

Answer #2 · Brent Wilson's Answer · The USDA Zones do change from time to time. Last I looked at the zone map it appeared that most of Atlanta would be in 8a. I'm on the Southside of Atlanta and when I entered my zip code in the zone finder it said 7b. With the more mild winters we've been experiencing over the past 25 or so years I'd say 8a. Either way, the zones aren't entirely accurate but are still a good gauge. For the most part, most plants that are hardy in 7b and 8b are also hardy in 8a.

Right now, we're working on a zone finder for Gardenality and, since the site is going global, are considering a global zone map.)

Answer #3 · DJ Meisenbach's Answer · I think it's surprising that hardiness zones change that drastically. It's interesting that the zones go according to temps from 97-05.)

Hi DJ-It is surprising the last few hardiness zone versions aren't updated more often. The newest map is generally one 5-degree Fahrenheit half-zone warmer than the previous map throughout much of the United States. This is mostly a result of using temperature data from a longer and more recent time period; the new map uses data measured at weather stations during the 30-year period 1976-2005. In contrast, the 1990 map was based on temperature data from only a 13-year period of 1974-1986.
