I am another NJ grower, in Jersey City, NJ since I am an apartment dweller LOL I have no way of storing figs in container in doors.
All of my varieties are in ground:
I got 3 year years old inground: Golden Celeste, Black Jack.
I got 2 more varieties that I clipped in the back of JC and Brooklyn NY and rooted this winter (also inground now), both seems to be super hardy as they survived winters of 2014 and 2015 without major limb damage while mine in ground died to soil level.
Regardless Both of my inground figs produced after getting killed to ground same season!
