It can take up to 10 years to bear fruit, depending on the age of the tree when it was planted. likely it will be on closer to 6-8 year mark. This would explain the poor fruiting. Since you are on the lower end side of the growing zone, you might need a little extra protection in the winter. Though the tree will settle in and survive in your zone, it may not bear fruit well, or at all without a little winter protection.
It would not hurt to test the soil for nutrient or pH imbalances. Having these in perfect range will increase the chances that you will see fruit.
