Pollination
Most fruit trees require pollination to produce fruit. Some trees are capable of pollinating themselves (self-fertile), others require pollen from another tree (self-sterile). As a general rule, pollenizers should be no more than 50 feet apart from one another, though trees up to 200 feet apart may cross-pollinize. The adjacent chart outlines the general requirements for common fruits. See the variety descriptions for more specific information. (Note - an insect or critter that spreads pollen from one plant to another is a pollinator, while a plant that produces pollen necessary to fertilize blossoms on another plant is a pollenizer.

Apples |
Require a pollenizer. Some varieties are pollen sterile and will not pollenize other apples. See descriptions and pollination chart. |
|
Almonds |
Most almonds require a pollenizer. The "All In One" variety is self fertile. Titan, a cold hardy almond, is pollenized by most peach trees |
|
Apricots |
Self-fertile |
|
Berries |
Most Berries are self-fertile, see descriptions. Plant two or more varieties of blueberries. |
|
Citrus |
Most are self-fertile |
|
Cherries, Sweet |
Most require a pollenizer, though some varieties are self-fertile (e.g. Stella and Lapins) |
|
Cherries, Sour, or Pie |
Most are self-fertile |
|
Figs |
Self-fertile |
|
Filberts |
Require a pollenizer |
|
Grapes |
Self Fertile |
|
Peaches |
Most are self-pollinating, though there are some exceptions, such as JH Hale & Indian Blood, that require a pollenizer |
|
Pears |
Require a pollenizer |
|
Plums - Japanese |
Require a pollenizer |
|
Plums - European |
Partly self-fertile, plant a pollenizer for increased production, see variety for specific requirements |
