What really helps with growing kiwi in the infamous Georgia clay is hoserkultur. Kiwis planted in a few inches of topsoil over a bed of clay are going to just get by at best. They need help to be able to sink their roots. Another way to help them is to companion plant a big, fat taproot like carrot or daikon radish right next to them.
My kiwis just barely got by until I got real aggressive drilling into the clay around their root zone and filling the holes with biochar, wood chips and compost.

Hi John, I'm in Atlanta too! I've got 3 kiwi, 2 female, 1 male. The females have grown well for three years, male only took off this year; no fruit yet. I'm training them up a high (6.5') deck, with passion fruit vine on the other side. They seem to prefer something with a bit of substance to grow up; rope, trellis, as opposed to wires. My aim is partly seasonal shade. I'm pruning to have fruit within reach from the top of porch deck.
