Your single trunk is probably ok, just did not have a bud ready at the base of the tree. Mine get frozen back but have lot's of early growth because they have a low bush form now and plenty of already formed buds from last year. I saw my first fig in NC at Ft. Bragg, it was a bush but about 30 ft. wide. Sadly it was destroyed when they tore down the old barracks. The figs were ho-hum anyway. But it does get cold in NC sometimes, I was there during an ice storm in 2004(i think) and everyone was freaking out!
Find some row cover Dominick, it does the trick for tomatoes and peppers. Talk to your local produce farmer and you might be able to get a short roll or two of the wide stuff, thicker is better for re-use, and it is the perfect nest for mice so be careful when you store it. It will also warm things up earlier for you.
