Answer: Brown Turkey can be grown outdoors in your area, however it is not at all unusual for it to freeze back to the ground in winter and then grow as a bush rather than a tree. It should be able to regrow and bear a crop of figs each summer nonetheless. In this instance, pruning would consist of removing the winter killed stems, and possibly thinning the new growth to five stems although I doubt this will be necessary. Here is some general information on growing figs in the ground you may find helpful.
Water stress can cause the figs to stay small and hard. These trees are drought tolerant when grown in the ground, but in a container you have to pay special condition to watering. This is especially true in hot summer weather. It should be in a large container and the soil should really be thoroughly moistened throughout when you water it in summer. (You not want it waterlogged, and the soil and container should drain out excess freely, but the soil should not be allowed to dry out.) Also, the container should be lifted up off the pavement several inches to allow air flow under it (reflected heat off a deck or patio is incredibly intense) and if possible, try to shade the container (just the pot, not the plant) at the hottest part of the day. Sometimes you can do this by putting another container plant in front of it to block the sun from hitting the pot, or by setting a piece of furniture in front of it.
I hope this helps you trouble shoot.
