It does take a little work to get figs to work in the North. But you have to work to get all of the rest of your fruit to produce as well.
Here are two inground trees from zone 6A, north of you in Western PA. Both were protected by being first pruned back to ~ 4 ft tall, branches tied together into a narrow ‘cylinder’, rings of insulation material (one home insulation roll, other was a couple layers of old pool solar cover) wrapped around the tree (like a big cylinder as well) and the center of the cylinder filled with pine bark mulch. Then covered with a tarp. They were uncovered late April, and both began leafing out on 5/13; the two pics were taken on 5/28 and 29. Both should produce MANY figs before frosts in October.
