Sour Cherry: full bloom - little fruit set

8 years ago

My North Star sour cherry tree was in a very full bloom this year despite the harsh winter we had. However, I see now that from all these flowers i am getting just few to set fruit. The flowering time was perfect for pollination - cool(not cold!), sunny, a lot of pollinators. Last year it was fruiting pretty well. So my question is - can harsh winter be a reason for luck of fruit from a lot of flowers, or my tree lucking some nutrients?
