Well, you can get potted stuff from a few nurseries all season long. Bare root is really winding down. A few might still have some end of season sales for another week roughly -- try Raintree, Stark, Miller's and see.

You could also probably find stuff locally.

I guess the main question is -- will you have time to keep it watered during the summer, along with everything else moving into a new house entails?

If you can, I say go for it. It takes time to get things growing.

If not, wait until fall. Sept through November should be excellent planting weather in Georgia, and some of the nurseries, such as Stark, sell a lot in the fall.

I agree with Denninmi- watering over the summer will be very important, especially for blueberries. I'd suggest using a soaker hose/drip irrigation to take some of the work out of it.

As far as a good nursery which ships potted plants, I would suggest Rolling River Nursery. Their prices aren't much higher than bare root, so I've been doing more and more of my buying there (I bought from 9 different nurseries this spring).

Berries Unlimited (3 gal blueberry plant is very nice, but very pricey), Backyard Berry Plants, and Whitman Farms are 3 other choices who ship potted berry plants. I don't think any of these sell apples and plumbs though, so Rolling River would be my suggestion for those. It would however limit your rootstock and variety choices a bit.
