My experience indicates if nobody else is growing it in your area you can expect a lot of work to have a chance of getting a successful crop, and even then it may not taste as good as it would if grown in the area with optimal growing conditions. The only parts of GA i have seen apples grown on a commercial basis is N Ga in the higher elevations. I have had a lot of trouble with fireblight getting my apple trees...

But, with a regular spray program and a clean orchard maybe you will have success! Good luck
