Many fruit trees require a pollinator in order to produce fruit, although there are a number of "self-fruitful" or "self-fertile" fruit trees available. However, even these self-fruitful varieties (including most sour cherries, peaches and nectarines) will yield a much better harvest with a pollinator close by. The tag on your new tree will give you valuable information about its needs. You may also like to check out our article on Caring for Fruit Trees.
How pollination produces fruit: Look at the blooms of a fruiting tree - each flower that is cross pollinated by another tree (through the work of bees, birds, and even wind) will turn into a piece of fruit. Those that are not successfully pollinated will die off and will not grow into fruit. Self-pollinators can receive pollen from their own blossoms, while trees that are not self-fruitful require the pollen from another tree in order to produce fruit.
How pollination works: Trees that are not self-fruitful require pollen from specific kinds of trees in order to produce fruit. As a general rule, two trees of the same cultivar (that is, two MacIntosh apple trees, for example), will not pollinate each other successfully. The best pollinators are two or more trees of the same type of fruit, but different cultivars, as long as they have the same bloom time (like Red Delicious and Gala, for example). It's very important that the pollinators have the same bloom time so that they have maximum exposure to each other's pollen. Pollinators need not be extremely close to each other, but they should be within 100 feet to increase the chances successful pollination.

So what pollinates what?
Check out our pages on specific fruiting varieties for more information on successful pollinators. Keep in mind that these are comprehensive lists and may include cultivars that are not native to our area. Click here to see a list of zone-appropriate fruiting plants that we typically carry. Peaches are all self-fruitful and do no require a pollinator.
