They need another tree for pollination, and not just one of the same variety, but a different variety of the same fruit. For example, most sweet cherries must be pollinated with compatible sweet cherry trees.
Subsequently, one may also ask, do all cherry trees bear fruit?
Some cherry trees are meant to never bear fruit. These are called flowering cherry trees and are grown exclusively for their blossoms. One example that grows in U.S. Department of Agriculture plant hardiness zones 5 through 9 is the Japanese flowering cherry tree (Prunus "Kanzan").
How long does it take for a cherry tree to bear fruit?
The tops of grafted trees are already one to two years old, while the roots may be two to four years old. Sour cherries, also known as pie cherries, generally begin producing fruit within three to five years after being transplanted in the garden. Dwarf varieties may produce fruit in one to two years.
Do fruit trees produce fruit every year?
The fourth most common reason fruit trees do not bear fruit is the effect from last year's crop. Fruit trees form their flowers the previous growing season. With apples and pears, thin the fruit down to one per cluster and allow only fruit bearing clusters every 6 to 10 inches.
