Could it be that, if they have consistently cold weather in the spring, the cold is keeping them dormant longer so they don't flower until after the danger of frost?

I have Pin Cherry trees, here in Pequot Lakes, Minnesota, where the
temperature rarely dips that low and my trees bear fruit only once or twice
in ten years. So what is the possibility that Pin Cherry requires bitterly
cold weather to bear fruit? Anyone have an idea???
