Hi guys. Have any of you left your fig trees in pots outside in winter? I guess my question is can they survive freezing temperature?

Eden
There is wide range of freezing temperatures.
They may survive at 30F to 32F and below it to -5C or just below it for hardy varieties. However I don't believe they will survive freezing temperatures in my location in January and February that could traditionallt/average reach -25C (-13F) and can occasionally dip to -22F during early morning hours.

Also

"Freezing temperatures" are one thing, but freezing rain, blowing winds with sleet, etc, and all that can drastically lower the temperatures and general conditions that impact a fig tree's survivability.

do not even try...

I second George's advice.  Don't even try.  I know Georgia isn't as cold as way up here, but there are plenty of fig guys who have lost lots of trees in Georgia winters.  But in-ground trees have also been known to do very well, at least in lower elevations.  Keep them out of the dry winter wind though.

Eden,
Yes.
10 gallon containers (half barrels), earth coupled (sitting on the ground), wrapped with a comforter and then covered with a tarp (they looked like small teepee tents). The teepee covered the entire fig plant and container. They were exposed to single digit temperatures and experienced minimal to no dieback. They were a fig winterizing experiment.

Hi,
Ok, another question: are you ready to loose them ?
The problem is that all rooting system is exposed to the freezing temps - even the deeper roots.
So if you have freezing temps, it is more likely that the trees will loose their roots and die .
Freezing tends as well to dry the trees and ground - so in that setup, the whole pot .
Because of the freezing temperatures, you would not be able to water those trees ... That makes too much constraints. 
I would at least bury the pots in the ground to help protect the roots - and this works.
Since last year, I have five like that - in 80 liters pots - to avoid rat damages.

Thank you guys.

as pete said, protected tree in southern states might work, if the tree is in good size container. 20+ container with nice wrap. sounds very tempting. Kathleen's Black i'm rooting this winter will go in ground come spring. KB is becoming very promising.

   I had 1 Verte tree that froze solid last winter (root ball was like a block of ice)...I thought for sure that it was dead, but come spring time it started leafing out and grew quite vigorously this past summer...having said all that, I wouldn't leave my potted fig trees out in the winter, because as a grower I have put too much time and effort into getting them to this stage...I notice that from your profile page you are located in Atlanta, Georgia, so maybe down there,with the warmer climate, you may get away with it, but here in the north-east (New Jersey) there's too much of a chance of loosing trees.

Is there a certain zone where you wouldn't protect a potted fig? Say zone 9-10? I'm on the gulf coast in South Houston and have about 10 potted figs in 1 gallon containers. In my zone would you leave them outside and only bring them in if the temps threaten to freeze? At what temp would you be concerned here? I know Steve, Megan and WillsC have potted figs in my zone and would like to hear there opinion. I have many blueberries in pots and a few citrus. I won't take any efforts to protect them unless it's going to get down to 28 or below which rarely happens here.

I've done it. ran out of room in the greenhouse and here are the ones that survived temps as low as 19F unprotected in 1 gallon pots against my house in upstate SC zone 7b/8

I have been wondering this myself and am having a hard time finding any data on what can survive Ohio's winter, especially since it has been so much more cold the last few years.  

So this year we're going to learn the hard way.  We left half a dozen different potted trees out, they're frozen and covered in snow now.  Good luck to them!
