Well here it is feb 10 2016 and very few of the figs I put into gallon pots have gone dormant. We have had a normal winter so far several nights in the 20's and many days in the 40's. Now the weather is really warming up and the foliage is starting to green up. My figs still are growing very green about a dozen have lost their leaves and seem to be dormant.
If they do not go dormant will they be good this spring?
What to do?

For the past 2 years I have placed my potted fig trees into an unheated greenhouse were temps have gone into the upper 20's, and 30's often.

It is not until now, after many such freezes that they all lose their leaves.  In early January most still had a good number of leaves.  If you have only experienced 20's a couple of times then I'm gonna go out on a limb and say the fig trees you have aren't going to lose all their leaves, some varieties more than others.

Short answer; they will be fine.

I was worried . Thanks don I feel much better on that.
