Bing cherries are used almost exclusively for fresh market. Bings are large, dark and firm cherries that ship well, but will crack open if exposed to rain near harvest. [1] A dry-summer climate is required for the harvest of the Bing cherry, making them especially well adapted to the climates of the Pacific Northwest and California.
The Van cherry tree is hardy, vigorous, and a heavy bearer, [5] but overloading can cause it to produce small fruit. [6] Like most cherry varieties, Van is self-incompatible; it can be pollinated by many other cherry varieties, including Bing, Montmorency, and Stella, among others. [7] Van blooms about 3 days before Bing. [2]
Sweetheart is a self-fertile cultivar which can be used as a "universal pollinator" for other cherry varieties with similar bloom time. [6] The flowers bloom about 2-3 days before Bing. [1] It is a very heavy producer, with overcropping being a potential issue. [7] The tree is highly susceptible to powdery mildew. [8]
Feb. 19—Q: My Bing cherry tree is over 30 years old. The cherries had been beautiful and delicious. The last two years, inside the cherries at harvest, there have been white worms. What do we ...
Trees that are cross-pollinated or pollinated via an insect pollinator produce more fruit than trees with flowers that just self-pollinate. [1] In fruit trees, bees are an essential part of the pollination process for the formation of fruit. [2] Pollination of fruit trees around the world has been highly studied for hundreds of years.

Self-pollination is a form of pollination in which pollen arrives at the stigma of a flower (in flowering plants) or at the ovule (in gymnosperms) of the same plant. The term cross-pollination is used for the opposite case, where pollen from one plant moves to a different plant.
About 10–15% of flowering plants are predominantly self-fertilizing. [9] Self-pollination is an example of autogamy that occurs in flowering plants. Self-pollination occurs when the sperm in the pollen from the stamen of a plant goes to the carpels of that same plant and fertilizes the egg cell present. Self-pollination can either be done ...
Self-compatible (SC) pollination systems are less common than self-incompatibile cross-pollination systems in angiosperms. [11] However, when the probability of cross-pollination is too low it can be advantageous to self-pollinate. Self-pollination is known to be favored in some orchids, rices, and Caulokaempferia coenobialis (Zingiberaceae).
