If pollinators such as honeybees, bumble bees and mason bees are scarce in your area, you can fertilize some fruit-bearing tree blossoms yourself. Self-fruitful trees, such as most apricots, peaches and tart cherries, may be pollinated with their own blooms. Self-unfruitful types, such as most apples, pears and sweet cherries, will need to be pollinated with another cultivar of the same fruit. Study detailed images of fruit blossoms first, if you aren't familiar with the names of the different flower parts. Identify the stamens, which have pollen-filled sacs called anthers at their tips.

Pollination of fruit trees is required to produce seeds with surrounding fruit. It is the process of moving pollen from the anther to the stigma , either in the same flower or in another flower.
Some tree species, including many fruit trees, do not produce fruit from self-pollination , so pollinizer trees are planted in orchards. The pollination process requires a carrier for the pollen, which can be animal, wind, or human intervention by hand-pollination or by using a pollen sprayer.
Cross pollination produces seeds with a different genetic makeup from the parent plants; such seeds may be created deliberately as part of a selective breeding program for fruit trees with desired attributes. Trees that are cross-pollinated or pollinated via an insect pollinator produce more fruit than trees with flowers that just self-pollinate.
Pollination of fruit trees around the world has been highly studied for hundreds of years. A few are described as "self-fertile" and are capable of self-pollination, although even those tend to carry larger crops when cross pollinated from a suitable pollenizer.
A relatively small number of cultivars are "triploid", meaning that they provide almost no viable pollen for themselves or other apple trees. Apples that can pollinate one another are grouped by the time they flower so cross-pollinators are in bloom at the same time. Pollination management is an important component of apple culture. Before planting, it is important to arrange for pollenizers — varieties of apple or crabapple that provide plentiful, viable and compatible pollen.
Orchard blocks may alternate rows of compatible varieties, or may plant crabapple trees , or graft on limbs of crabapple. Some varieties produce very little pollen, or the pollen is sterile , so these are not good pollenizers. Good-quality nurseries have pollenizer compatibility lists. Growers with old orchard blocks of single varieties sometimes provide bouquets of crabapple blossoms in drums or pails in the orchard for pollenizers.
Home growers with a single tree and no other variety in the neighborhood can do the same on a smaller scale. During the bloom each season, commercial apple growers usually provide pollinators to carry the pollen.
Honeybee hives are most commonly used in the United States, and arrangements may be made with a commercial beekeeper who supply hives for a fee. Honeybees of the genus Apis are the most common pollinator for apple trees, although members of the genera Andrena , Bombus , Halictus , and Osmia pollinate apple trees in the wild.
Apple growers also rely on several species of wild bees for pollination in their orchard. Increasingly Orchard bees spring mason bees, genus Osmia are being used in fruit tree pollination.
Symptoms of inadequate pollination are small and misshapen apples, and slowness to ripen. The seeds can be counted to evaluate pollination. Well-pollinated apples have best quality, and will have seven to ten seeds. Inadequate pollination can result from either a lack of pollinators or pollenizers, or from poor pollinating weather at bloom time. Like apples, pears are self-incompatible and need to attract insects in order to be pollinated and produce fruit.
Bees may abandon the pear blossoms to visit dandelions or a nearby apple orchard. The majority of pollinators of pear trees are honey bees , although pears are also visited by blow flies and hoverflies.
Bee attractants may include pheromones that mimic the brood pheromone or the juvenile pheromone, or other attractants. One is saturation pollination , that is to stock so many bees that all area blossoms are worked regardless of the attractiveness to the bees. Another method is to delay the movement of the beehives into the orchards until there is about 30 percent bloom.
The bees are moved into the orchard during the night and will usually visit the pear blossoms for a few hours until they discover the richer nectar sources. The recommended number of hives per acre is one. Most Asian plums require a second variety for cross-pollination, whereas most European plums are self-fertile. European plums that dry well are also called prunes, the common name for the dry fruit.
Several of the Asian plums bloom early and pollinator management is similar to apricots. However the fruiting wood especially of Asian plums can be brittle and over-pollination requires aggressive thinning of fruits. Apricots are botanically similar to almonds and like almonds they can bloom early, making pollinator management similar except that a tree can overcrop if the fruit is not thinned.
Most peaches and nectarines are self fertile and thus require fewer pollinators than apples and pears. Pie cherries, also called sour cherries, are self-fertile. In some varieties, fruit yield could increased by utilizing pollinators.
Pie cherries can pollinate sweet cherries. Cherries do not need thinning. Some figs produce fruit without pollination. Figs that are pollinated rely on fig wasps. The blossoms of most California [Almond] varieties are self-incompatible, requiring cross-pollination with other varieties to produce a crop. The single most important factor determining a good yield is pollination during the bloom period.
More than a million colonies of honey bees are placed in California Almond orchards at the beginning of the bloom period to pollinate the crop. California beekeepers alone cannot supply this critical need, which is why honey bees travel across the country to the San Joaqin Valley each year.
Although the recommended number of hives per acre is 2 to 3, due to the high demand in conjunction with the reduced availability of commercial beehives, many almond growers have to make do with a lower hive density during pollination. These growers started using semiochemical formulations, like SPLAT Bloom,  to compensate for the low hive density.
SPLAT Bloom manipulates the behavior of the bees, inciting them to spend more time foraging, and thus pollinating flowers in the entire almond orchard increasing pollination and fruit set , not only close to the hive. Research into self-fertile almonds has led to the development of several almond varieties that do not need a pollinator tree. Working from an old Spanish variety, "Tuono", researchers in started making available new self-fertile varieties that more closely match the qualities of the popular "Nonpareil" almond—including varieties "Lone Star" and "Independence".
Almond growers with self-fertile almonds report excellent nut set with half or less the number of bees in the field. Hazelnuts filberts , walnuts, pecans, and chestnuts are all wind-pollinated temperate-zone nuts.
Mostly these wind-pollinated nuts are selected varieties that need two different varieties and favorable winds for cross-pollination. Insects and birds may visit and consume the pollen, but are not a factor in pollination.
Edible seeds from wind-pollinated coniferous trees such as pine, ginkgo, and monkey-puzzle trees are also harvested and the seeds are colloquially called nuts. Many citrus cultivars are seedless and are produced parthenocarpically without pollination. Some cultivars may be capable of producing fruit either way, having seeds in the segments, if pollinated, and no seeds if not. Some citrus, such as Meyer Lemons , are popular container plants. When these bloom indoors, they often suffer from blossom drop because no pollinators have access.
Hand pollination by a human pollinator is a solution. A few citrus,  including some tangelos and tangerines , are self-incompatible, and require cross pollination. Pollinizers must be planned when groves are planted. Managed honeybee hives at bloom time are often used to ensure adequate pollination. Most edible passion fruit varieties are self fertile.
Since each flower is only open for 1—2 days and may not get the chance to be pollinated by insects, fruit set can improved by hand pollinating. Mangoes are usually self pollinating and also grown by grafting [ citation needed ]. From Wikipedia, the free encyclopedia. Pollination Biology, Vol. Switzerland: Springer International Publishing.

Nicolaus critterologist October 21,One taste of a crisp, tree-ripened apple can make you dream of planting an orchard of your own someday. A home orchard doesn't need as much space as you might think, but it does require some planning, especially if your space is limited. Many fruit trees need another variety for cross-pollination. Even self-fruitful varieties will bear bigger crops with another tree nearby. Proper spacing helps with pollination as well as with fitting in more trees.
In the flower, pollination is the transfer of pollen from the anther to the stigma. After pollination and fertilization, fruit set occurs.
Fruit Tree Spacing & Pollination Guide
In particular, can apple trees pollinate with pear, cherry, or plum trees? I did some research to find out more. Generally, apple trees cannot cross-pollinate with pear, cherry, plum, or other fruits. This is because their genetics are too different and fertilization cannot take place. While there are some cases of apple trees successfully crossing with pear trees, the resulting fruit was found to be sterile. Even though there are some cases of apple trees pollinating with pears, the results are often sterile although, some work has successfully created apple-pear hybrids that can reproduce. But, what can actually pollinate apple, pear, cherry, and plum trees? And are there self-pollinating trees for each? The best pollinators for apple trees are other apple trees.

Our Feedback just received my order in very good condition and very fast excellent Roger Bone, Great Yarmouth. Fruit Tree Pollination Simplified hopefully Fruit tree pollination is a subject that concerns and confuses many; we have tried to simplify things! As the name suggests, trees that are described as self-fertile will produce fruit on their own - tjat is, without the need for another tree to pollinate their flowers. This is the same for those trees that are described as being partially self-fertile, though yield may be fairly small - so we recommendplanting a suitable compatible pollinator to ensure a good harvest.
How important is proper fruit tree pollination? Without pollination, fruit will not develop.
Like most fruit trees, contemporary cultivation methods suggest that apples are ordinarily propagated asexually by grafting. In the wild, apples grow from seeds. Rather than inheriting DNA from their parents to create a new apple with those characteristics, they are instead significantly different from their parents. This means that if we plant the seeds from 10 apples of exactly the same variety, all 10 apple trees that will be created will be significantly different and will give accordingly different fruits. Consequently, professional farmers choose grafted seedlings, in order to achieve product uniformity and quality.
Factors Affecting Pollination and Fruit Set in Olives
Fruit tree pollination is very important when selecting trees. One of the most common question asked when planting fruit trees is how many trees do you have to plant in order to get fruit. It can be a bit confusing as some fruit trees will produce fruit by themselves self-pollinating while other types will need 2 or more different varieties in order to set fruit. Plant two or more different varieties for cross pollination to bear fruit. Flowering crabs and wild apples will serve as pollination too.
The Navel Oranges seen in the photo at the top are a good example of a fruit that can self-pollinate. Most fruit trees -- pears and apples in.
Pollination of apple trees and other fruit trees
I recently moved into a new home that had several fruit trees, and I have added more fruit trees this spring. I am assuming that you are asking about which of your fruit trees will require another compatible tree to pollinate the tree and not about honeybees or another insect that would help pollinate the flowers. Almost all fruit trees will require some help from insect pollinators to have a good fruit crop. They are what horticulturalists call self-fertile.

In order to have fruit from apple and pear trees, you need a second tree for cross-pollination.
Apple Tree Pollination – Choosing The Perfect Pollinator
January is not too early to start to plan for a new home orchard or to consider replacements for aging fruit trees in an existing orchard. There are several different kinds of fruit trees to consider, including apple, cherry, peach, pear and plum. As we live in the northern portion of Illinois, apple is likely the main fruit tree grown in back yards and commercial orchards. Certainly at the commercial level you will be able to pick just about every fruit you want, but in the home orchard, apples are a good place to start. When you shop the fruit tree catalogs or visit with your favorite retail garden center, find out what cultivars or varieties they will be carrying this spring. Homeowners should consider dwarf apples, as in most cases, yard space is limited. Dwarf apple trees are naturally smaller than their full-sized siblings, and are much easier to train, prune and maintain than a full-sized fruit tree.
