Georgia planting zone questions

What planting zone is Georgia?

Georgia has USDA plant hardiness zones 7b to 9a on the 2023 USDA map. The most common zone by county is 8b (70 of 159 counties), then 9a (41).

What does a hardiness zone mean?

A USDA zone is based on the average coldest winter night from 1991 to 2020. Each zone is 10°F wide, split into a and b halves of 5°F.

Did the zones change in 2023?

Yes. USDA released a new map in November 2023 using 1991 to 2020 data. Many places moved half a zone warmer than on the 2012 map.

Does my zone tell me when to plant?

No. Zones are about which perennials survive winter. Planting dates follow frost dates; see Georgia frost dates and the Georgia planting calendar.

How is a county's zone worked out here?

From the USDA 2023 zone of each ZIP code, joined to Census ZIP code areas. The main zone covers most of the county's ZIP code area.

Can I use the USDA map image?

USDA publishes the official map as a public-domain image. The map on this page is the official file, reduced in size, with a link to the full-size version.
