In order for fruit to develop, pollination must occur at blossom time. Pollination is the transfer of pollen from the male part of the flower to the female part of the flower. Some types of fruit trees may be pollinated with their own pollen and are considered self-fruitful may need another tree of same variety or self-pollinating no need for a separate pollinizer. Other types of trees require pollen from a different variety of the same type of tree and are considered self-unfruitful or self-incompatible.

Fruit Tree Spacing & Pollination Guide

Flowers of all edible tree species require pollination, which is the transfer of pollen from the male part of a flower stamen and anthers to the female part of a flower pistil and stigma. Pollination fertilizes flowers so the tree can produce fruits, nuts, berries, seeds or pods. When selecting trees, find out how they are pollinated and use this information in determining what trees to plant and where to plant them. Start by reviewing the types of pollination below.

These trees can be planted alone and still produce fruit, nuts, seeds or pods. However bees are often necessary to transfer the pollen. Examples of self-pollinated fruit trees are sour cherries, apricots, and peaches. Small fruits, including raspberries and blackberries, are also primarily self-pollinating.

Many need bees to transfer the pollen. For edible trees that require cross-pollination, it is best to have more than one variety of the same type of fruit tree in your yard, neighborhood, or community.

Keep in mind that different varieties may flower at different times--in early, mid- or late season, so plant those that bloom at the same time. Sweet cherries, pears, and most apples require the presence of two different compatible varieties for pollination to result in fruit set. Many fruit trees, such as peach, pear, and apple require honeybees for pollination. Cacti and succulents are often pollinated by moths, bats, and birds. Many of these pollinators are susceptible to insecticides and genetically modified plant pollen.

Do not apply insecticides or other chemicals to plants that could damage pollinators. For ensure sufficient pollen reaches flowers, several trees of the same species need to be planted within 50 feet of each other. Pinyon pine, juniper, pecan and pistachio are naturally wind pollinated. A male tree is needed in the vicinity to pollinate the female tree to ensure production.

Date palms, carob, pistachio and persimmons are examples of dioecious trees. Make sure that you seek professional advice when ordering and planting these trees. Peach, Self-Pollination. Apple, Cross-Pollination. Date Palm, Male and Female Trees. Review pollination information when choosing your edible trees. More information about pollination of Arizona edible trees is available at the Edible Tree Directory. If your trees require cross-pollination, you may need to provide space for two different compatible natural or cultivated varieties of the same edible tree type.

Even self-pollinating trees may produce higher yields if they are cross-pollinated. Look around your neighborhood and community—if other people are growing the same types of edible trees, these may be able to pollinate your tree. Special grafted trees may have two varieties grafted onto the same rootstock for effective pollination. Or some female trees may have limbs of male trees grafted onto them. Ask a Cooperative Extension or nursery specialist for more information about which trees to plant for cross-pollination and fruit set.

In some cases, if pollinators are scarce or you want to increase yields, you can hand pollinate blossoms. W e recommend hand-pollination only in special circumstances, since it requires careful attention each spring when the blossoms open. Dwarf trees and container-grown trees are easiest and safest for homeowners to hand pollinate.

First, familiarize yourself with flower anatomy. Identify the multiple long male stamens, which have pollen-filled vessels anthers at their tips. Find the female pistil, which rises from the flower center as a thick, columnar structure with a sticky crown stigma for receiving pollen.

Wait until the trees are in full bloom and the flowers are fully open. Use a small artist's brush or cotton swab to hand pollinate the flowers on smaller trees. To cross-pollinate, prune blossoms off of one tree and carry them to another tree of the same type that is also in full bloom. Using your brush, swab or simply the blossoms themselves, apply pollen from the anthers of the flowers in your hand to the stigmas of the flowers in the second tree.

If the tree is large, use a duster attached to a long pole. To cross-pollinate, brush the duster on flowers of one tree, carry it a second tree. Continue this for successive days as more blossoms open. While professional growers of date palms often hand-pollinate the flowers on many female palms using pollen from a single male palm to make sure that each raceme of flowers is pollinated, these, and other tree types can be too tall for most home orchardists to effectively and safely pollinate.

Pollination Groups

Peach except J. Hale , nectarine, apricot, grape, brambles, strawberry, sour cherry, currant, gooseberry, and jostaberry do not require cross-pollination but do require bee activity for the best fruit set. Many of the European and Japanese plum cultivars are self-fruitful. Consult catalogs and reference books for information on specific cultivars. Apples, pears Asian and European , and most sweet cherries are generally self-unfruitful and require pollen from another variety within feet to produce a good crop.

Fruit trees are insect-pollinated, with the open, bowl shape of the flowers making them easily accessible to bumblebees and other.

Factors Affecting Pollination and Fruit Set in Olives

Firman Pollen Co. The trees have trellises, grow tubes and irrigation. Harvesting and spreading pollen as a way to supplement the job of honeybees is nothing new. Firman has been doing that since , but it usually gets the pollen after thinning for optimal fruit production. Firman plans more acreage of pollen trees this year — 9 more acres of cherries and 2 acres of bare root pears. McClure admits this is an experiment. All the horticulture instructions and expertise of the fruit industry is geared to produce fruit. McClure and his collaborators have yet to determine the best cultivars, training systems, irrigation plan and nutrition regimen.

Fruit Trees: It Usually Takes Two

There is something special about being picking a piece of fruit off a tree in your own garden. Some trees can grow to take up a lot of space while others can be kept quite small to adapt to your garden size. If you live in an urban jungle with little space on your patio or a home in suburbia with plenty of surrounding space in your backyard — there is always a way to create a thriving outdoor space full of fruitful plants, shrubs, and trees. Depending on the variety you choose, some fruit trees are self-pollinating and some require a pollinator. Self-pollinating fruit trees include apricots, nectarines, peaches, and sour cherries; whereas fruit trees that require pollinators include apples, pears, plums, and sweet cherries.

Many of our crops are dependent upon animal pollinators; one of every three bites of the food we eat is thanks to insects, birds, bats, and other pollinators.

Fruit Trees

If you are planting more than 3 varieties of one type of fruit tree, don't give it too much thought - you'll have no problems. If you are planting just one tree in an urban area, chances are high that your neighbours have done something similar and you'll get pollination from a nearby tree. If worried, or after a couple of years of no fruit, simply plant a couple more different varieties. If you are planting a variety of apple that doesn't produce viable pollen triploid , you must have separate varieties nearby so it will set fruit. For people who aren't satisfied with the above, we've included a longer explanation bellow. If what you read above was satisfactory, don't bother reading the part on flowering times below, as it may just confuse you. Generally, pollination needs two things.

Most plum trees need a different variety to cross pollinate. The second tree must be the same type, because European and Japanese types aren't.

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.

By Michael Thomsen For Dailymail. Scientists in Japan have found they can pollinate fruit trees using soap bubbles coated in pollen. A team of researchers from the Japan Advanced Institute of Science and Technology, led by Eijiro Miyako, created a soapy solution that can be blended with up to 2, pollen grains per bubble and blown out of a plastic gun or dropped from above via drone. Scientists at the Japan Advanced Institute of Science and Technology developed a new method of pollinating plants and fruit trees using soap bubbles coated with pollen. Maybe I still am now. The idea came to Miyako one day while he was playing with his young son, who was accidentally hit in the face by one of the soap bubbles they had been blowing.

We are updating our website and ordering will be available for our Canadian customers soon.

For many fruit trees, you need more than one cultivar in order to ensure a good harvest. Tempted by the idea of growing your own fruits? It can be very rewarding and is not all that difficult, but … you first have to have some inkling of the curious sex habits of fruit trees and small fruits. Cross-pollination is mandatory for the vast majority of temperate-climate fruits including apples and most plum, cherry and pear trees. So, for easy fruit production, the simple solution is to always plant two or more cultivars of any fruit tree. Of course, the pollen must come from a closely related plant.

Note : Pollination requirements are discussed in Varieties for Planting in the Home Garden, linked near the bottom of each crop page , e. With few exceptions, fruit will not form until pollen from male parts are transferred to the female parts of a flower. Without pollination, flowers may bloom abundantly, but will not bear fruit. Pollination is the transfer of pollen to the stigma from stamens of the same or a different flower.
