Hi Arlene,
Yes, if you intend to grow them in the ground, you MUST put them right up against a South wall- they will need the radiant heat from the wall at night to get them through the cold snaps. The wall acts as a heat reservoir- gaining heat all day as the sun shines on it, then slowly, releasing it at night.
As for purchasing Satsumas, these days most Lowes stores carry them. If you want, simply call your local Lowes store and ask for the LNS (Live Nursery Specialist). Each store has one and this is the person who will generally know what is coming and can also place an order. Since Georgia does not have any commercial plantings of Citrus that I am aware of, I do not think there are any issues regarding shipping into the state (Unlike Texas and Louisiana- our stuff must be produced in the state to be sold here..quarantine issues). These are the things Elaine is alluding to, along with, I believe, Citrus Canker.
Anyway, as I mentioned, Satsumas, along with other Citrus, are getting to be a staple at Lowes stores. Oddly, I was visiting relatives in Iowa a couple years ago and guess what? Citrus in Iowa Lowes! Yup...
You might also find a number of Kumquat trees along with the Citrus. Very cold hardy and a delightful little form of Citrus.
