Will a carmine jewel cherry tree act as a pollinator for a bing cherry tree?

Yes, a Carmine Jewel cherry tree can act as a pollinator for a Bing cherry tree. Carmine Jewel is a sour cherry variety that is self-pollinating but also produces viable pollen that can benefit other cherry varieties. Since Bing cherries are not self-pollinating, having a Carmine Jewel nearby can enhance fruit set and yield. Planting both together can improve overall cherry production.
