In 7a you can zone push by planting them on the south facing side of a structure like a house, shed, rock outcrop ext. Anything to basicialy stop the northly winds from damaging your tree and absorb heat during the day and transfer it back out at night when the temps get the lowest. Some people that make perfect micro climates for their trees don't even wrap them in 7a but if you want to play it safe keep it in a pot. One thing I will add is let it go dormant when its time. So many new fig growers bring them inside in fall and overwinter them in a sunny window don't do that. It wants to go dormant and you don't want plants that where outside in your home or soon you'll have gnats and whatever else was in the soil in your home. An unheated garage or shed is a good place to store fig trees. Unheated basements and root celers work great also.
