I have a relative from northeast Tennessee visiting and I am giving him a couple of  young  Celeste fig trees started from cuttings this spring.They are about a foot tall in gallon pots. I'm in Louisiana and was wondering if you all have any advice for planting a fig tree that far north. 

For me, I would keep them in pots till they are bigger, probably outgrowing a 5g pot, and plant in the Spring.

They should probably stay in their pots till spring. If the pots are buried partially for the rest of the season the fig will be able to send out roots throught the drainage holes and grow better, need less watering, and still be brought in for the winter. They could then either go up to larger pots or get planted out and protected during their first few winters. Older wood will stand more cold, and be careful with the fertilizer for in ground trees because a vigorously growing fig is also less hardy. If the soil is silty or clay nutrients will be held longer than sandy soil.
The figs will do better planted in "microclimates" such as south facing walls and slopes.

Those guys have good advice - I'm just a newbie.  However, here is my experience in Middle TN.  I planted what was marked a Celeste in the ground from a 1 gallon pot.  Basically no protection from anything - although my lot is surrounded by big trees and honeysuckle covered fences.  It has died down to the ground every year since planted.  It was also unknownngly undermined by moles for a couple of years and is growing back from that.  A year later I did the same with what was tagged Brown Turkey.  Planted it on the NE corner of the house.  But it is thriving.  I rooted some cutting from an unknown inground tree I've known about for several years now.  I gave two away to friends and they planted them after about a year and they have survived.  However, the ones I had still in pots did not - the new, small trees in the pots will need to be protected in the winter. 

Thanks, I am going to tell him to keep them potted and protected until spring.
