Pollinator: bats, bees, moths, anything that can move pollen.
Pollinizer : tree or plant providing pollen to the pollen source.
Cross Pollinization : the transfer of pollen from the flower of one plant to the flower of a plant having a different genetic constitution.
Self Fertile : capable of self-pollinization. Although it is not necessary for self-fertile trees to be cross pollinated, they are more productive if they are.
Think of each different variety of apples as a "family". For pollination you need to have two different apple varieties or "families"! In tackier terms, (so sorry!) they don't like incest. Apples also do not pollinize other fruits. The EARLY SEASON bloomers and the LATE SEASON bloomers will not cross pollinate because their bloom time is too far apart and the early varieties will be done blooming before the late ones start. The closer the two varieties are in bloom time, the more their bloom will overlap and the more likely you will get pollination and therefore set fruit.
Our Apple page is color coded as to what apples work together. Please check it out for reference. Also, Crabapple trees make EXCELLENT pollinators for apple trees. They blooms longer, so it covers more apple tree pollination.
Most varieties of peach trees are capable of self-pollination. This means that they contain both the male and female parts of reproduction on each flower. It also means that the tree is capable of making fruit and seeds on its own. This is a great advantage to those who want a peach tree in their yard, but don't want to have more than one.
Most pear varieties need to be cross-pollinated by a different variety in order to produce bountiful crops, although a few are self-fruitful. To be safe, unless otherwise noted in the description, it's best to order at least 2 different varieties of pears to insure good pollination. Most pear trees that bloom at the same time are suitable pollinators. Or as long as the second tree is within 500 feet pollination should occur. Within city limits, most apple and pear trees will be pollinated by insects carrying pollen from the neighbors’ trees. With small amounts of nectar and low sugar content, pears require more pollinators than any other fruit. All the pear trees we carry bloom in early May. They all should work together as good pollinators except for the Luscious, which is sterile!
Some plum tress are self-fertile, but many require a compatible plum tree nearby (plum trees are not so common as apple trees) for pollination to occur. Plum trees have a short and very distinct pollination period (almost exactly ten days) so if you choose a tree which is not self-fertile, be sure to also choose a compatible tree. Plum trees can only be pollinized by other plum trees. The Toka Plum is the best pollinizer. All the trees we carry bloom in late April, with exception to the Pembina which is early May.
Sour cherries are self-pollinating; only one tree is needed for fruit production. Most sweet cherry trees require a pollinator.
Blueberries are self-pollinating, however more than one variety will increase production, ripens earlier and the fruit can be larger!
STRAWBERRIES AND RASPBERRIES
They are both self-pollinating.
