Cross-pollination is essential for apples, pears, most sweet cherries, and most Japanese plums. Cross-pollination is not essential, but does improve the number of fruit that form on apricots, European plums/prunes, tart cherries, peaches and nectarines. Pollen is primarily transferred by honeybees.

Can I cross pollinate my apple trees?

Generally, apple trees can be cross pollinated with flowering crab apple trees which are grown for decoration over fruit. If you’re within city limits, you can most often just plant one tree and get fruit. If your tree doesn’t produce fruit to your expectations there are several reasons for low yields in your fruit trees including:

Do apple trees need pollinators to produce fruit?

Apple Trees That Do Not Require Pollinators. Apple trees produce more fruit if there is a different type of apple tree planted nearby so they can cross-pollinate with the help of bees. Some apple trees cannot produce any fruit without a pollinator.

Do McIntosh apples cross pollinate with other varieties?

Closely related cultivars such as McIntosh, Early McIntosh, Cortland and Macoun do not cross pollinate well with each other and spur types do not pollinate the parent. Bloom periods of cross varieties of apple for pollination must overlap.

Why is pollination important for Apple Blossom?

Pollinating insects such as bees work hard at this job, which is one reason why it’s so important to plant pollinator-attracting flowers in among our crops – to keep them on side and coming back! Wind will also help to pollinate apple blossom.

Do I need 2 apple trees to get fruit?

Apples are pollinated by insects, with bees and flies transferring pollen from flowers of one apple tree to those of another. But you don't need to plant a whole orchard to enjoy apples right off the tree. Two trees will reward any family with enough fruit to enjoy and share with friends.

What apple trees do not need cross-pollination?

Varieties of Self-Pollinating ApplesAlkmene.Cox Queen.Granny Smith.Grimes Golden.

Can a single apple tree produce fruit?

One tree is not enough To set fruit, the vast majority of apple trees require a different variety grown nearby for pollination. While some apple varieties are self-pollinating, even they produce more fruit with another variety nearby.

Are any apple trees self-pollinating?

While some varieties of apple are able to fertilize themselves (trees described as 'self-fertile'), others require pollen from another tree to do the job – a process known as cross-pollination.

What apple trees should be planted together?

However, most apples require not only a second apple tree to pollinate, but a second tree of a different cultivar (for example, a Pink Lady Apple should be paired with a Gala, Fuji, Granny Smith or McIntosh Apple to produce fruit).

Can a pear tree pollinate an apple tree?

It is best to pollinate fruit trees of the same genus with each other — apples with apples, or pears with pears — but pears can cross-pollinate with apples, as long as both trees bloom at the same time. The other cultivar in yard is sterile.

Why does my apple tree have no apples?

Most apples need one or more pollination partners to produce fruit. Other fruits can be incompatible with each other. Frost and low temperatures can affect all fruits, but especially the early flowering plums, nectarines and peaches, by damaging the fruit buds. Spring frosts are the commonest cause of poor fruit crops.

What is the best self-pollinating apple tree?

Some self-fertile varieties include Golden Delicious, Braeburn, Granny Smith, and Scrumptious. Check the Home Orchard Society for a more thorough breakdown of self-fruitful varieties — there are quite a few. Keep in mind, however, that even self-fertile apple varieties will bear more fruit if cross-pollinated.

How close do apple trees need to be to pollinate each other?

a 100 footFor pollination purposes, the recommended planting distance for apple trees is within a 100 foot distance. To summarize, nearly all apple varieties need to be cross-pollinated with pollen from the flowers of a different apple variety to produce fruit.

What fruit trees do not need cross-pollination?

Self-pollinating fruit trees include apricots, nectarines, peaches, and sour cherries; whereas fruit trees that require pollinators include apples, pears, plums, and sweet cherries.

How many apples will one tree produce?

How many apples does an apple tree produce? From 0 to over 800. A very good yield for a well-cared apple tree grown in a backyard is about 80-150 fruits per season.

Do you need 2 fruit trees to produce fruit?

You only need to plant one variety to produce fruit. Sweet cherries are more difficult and certain varieties are incompatible with each other. Bing, Lambert, and Napoleon do not pollinate one another. Plant a pollinating variety such as Black Tartarian, Republican, Van or Windsor.

How do I get my apple tree to bear fruit?

In order for fruit to be produced, most trees must be pollinated. Cold weather and a reduction in pollinating insects can cause trees to blossom but bear no fruit. For best results with apple trees, plant two different varieties close together for cross pollination.

Do the flowers on an apple tree turn into apples?

Fruits develop from the base of the apple flower after pollination and fertilization and the flower walls around the seed cavity expand to become the fruit flesh.

Why is my apple tree not producing fruit?

If your apple tree isn't producing fruit despite the fact that neighbors on either side of your house have apples trees too , it may be that the trees are not compatible. To be pollinating partners, apple trees must be different varieties of trees. So, if there was a sale on Fuji apple trees at the local garden store and everyone on your block installed a Fuji tree, then pollination would not be possible.

How to identify apple species?

The nursery trade has made this easier by identifying apple species by pollination group. They label species that blossom by pollination periods. Some list the apple species in three blooming times (early season, mid season and late season), while others label them from A to D according to blossom periods (earlier pollination group A, with succeeding groups labeled B, C and finally D). This simplifies the process of finding a compatible pollination partner: Determine the group in which your apple tree falls and select another variety from the same group for best results.

How many blooms does an apple have?

Some list the apple species in three blooming times (early season, mid season and late season), while others label them from A to D according to blossom periods (earlier pollination group A, with succeeding groups labeled B, C and finally D).

What are the parts of a flower that are covered with pollen?

The stamen includes the filament and the anther, where the pollen is found. You can recognize those parts on many flowers as the tall, pointy parts extending from the center of the flower that, in season, are covered with fluffy pollen. The plant pistil also includes several parts.

When do apple trees bloom?

Which Trees Bloom When. Some apple varieties bloom while it is still technically winter, while others come into flower in late spring. The trees on average flower for a week or two, so you need to find pollination partners that have flowering periods with significant overlap.

Do apple trees need pollination?

If you want your apple trees to produce apples, the blossoms need to be pollinated. This involved a transfer of pollen from the male parts of an apple blossom to the female parts, a task usually accomplished by bees.

Can you prune an apple tree at the same time?

Those gardeners before you have come up with several solutions you might try. One possible solution is to find a pollinator tree that is in blossom at the same time as your apple tree. With permission from the tree's owner, you can prune off a few branches full of blossoms and carefully transport them to your yard.

When do apples bloom?

All apple varieties have varying blooming periods throughout the spring and summer. To increase pollination chances, plant cultivars that have similar blooming periods -- cross-pollination cannot occur if one tree is in full bloom with no flowers on the other variety.

How do insects move pollen from a flower?

Moving between flowers for sustenance, insects press the grains removed from the flower stamens onto other stigmas. As a result, the flower becomes fertilized as the grain forms a tube to move the pollen down into the ovule.

How far apart should I plant an apple tree?

Standard-size apple trees have the largest spacing of up to 100 feet.

When do white blossoms bloom on an apple tree?

By Amy Rodriguez. Fragrant, white blossoms decorate your apple tree (Malus domestica) in the spring and summer for a bountiful fruit harvest come fall. Thriving in U.S. Department of Agriculture plant hardiness zones 3 through 8, the majority of apple cultivars require a second plant for pollination. Choosing the correct apple variety ...

Do apples pollinate better than other types of apples?

Good Apple Pollinators. Some apple varieties produce more pollen grains than other types. If you have several apple trees in your garden, you create better pollination chances if you include a "Golden Delicious" or "Red Delicious" variety in the group.

Can you plant a Jonagold apple tree?

If you want to cultivate a "Jonagold" or "Winesap" apple tree, you should plant a minimum of two other cultivars nearby for pollination. Both "Jonagold" and "Winesap" do not have fertile pollen and fail to pollinate other trees. By diversifying your garden with other apple varieties, these trees will be just as successful at fruiting as common "Red Delicious."

Do apple blossoms self pollinate?

With perfect flowers, apple blossoms have the potential for self-pollination -- each blossom houses both male and female reproductive parts. However, seed production has better diversity and genetic strength with cross-pollination. As insects feed on the flowers' nectar, pollen grains adhere to their bodies. Moving between flowers for sustenance, insects press the grains removed from the flower stamens onto other stigmas. As a result, the flower becomes fertilized as the grain forms a tube to move the pollen down into the ovule. However, successful apple fertilization does not occur unless the cross-pollination process mixes two different varieties together. For example, a "Red Delicious" cannot fertilize another "Red Delicious" tree.

Why do apples need pollination?

Like all fruit trees, apples need to be pollinated if they are to set fruit. This involves the transfer of pollen from the stamen (the male part of the flower) to the stigma (the female part). Pollinating insects such as bees work hard at this job, which is one reason why it’s so important to plant pollinator-attracting flowers in among our crops – to keep them on side and coming back! Wind will also help to pollinate apple blossom.

Why do people grow apples?

But aside from the obvious benefits of freshness, flavour and frugality , there are plenty of other compelling reasons to grow a tree or two of your own. With supermarkets and food stores offering just a meagre selection of varieties, perhaps the biggest advantage is access to the literally hundreds (and possibly even thousands) of exciting options open to the kitchen gardener. No other fruit has so much tradition, folklore and abundance associated with it. The home grower is very much spoilt for choice.

What group of apples are in flower?

Apple varieties, like plums, pears and other fruit trees, are grouped according to when they flower. The earliest pollination group to blossom is group A, followed by groups B and C and, bringing up the rear towards the end of spring, group D. Any respectable fruit nursery will catalog the varieties it offers according to pollination group, making the selection process considerably simpler. Needless to say it’s best to pick varieties from the same group to ensure they will be in flower at the same time, though varieties from adjacent groups will offer some overlap and hence pollination success.

Do apples need pollen?

While some varieties of apple are able to fertilize themselves (trees described as ‘self-fertile’), others require pollen from another tree to do the job – a process known as cross-pollination. In all cases, however, a higher rate of fruit set will be enjoyed when trees are cross-pollinated, so a small group of trees is always better than one lonely specimen, even if it is self-fertile.

Do all apples blossom at the same time?

Of course, not all apples blossom at the same time and, to add another player into the game, not all varieties are necessarily compatible. Certain types called triploids require not one but two other fruit trees to ensure good pollination – and these mustn’t be other triploids. This might rule out triploid varieties for some, but a number of popular, good-tasting apples – for example, ‘Bramley’s Seedling’, ‘Ribston Pippin’ and ‘Jonagold’ – happen to be triploids, making them worth the apparent effort.

What is the primary pollinator of apple trees?

Honeybees are the primary pollinators of apple trees. Because of this, the distance is judged by how far the honeybees are willing and able to fly between the trees. As the bees collect pollen from the male flowers, they then travel to the other tree and the pollen spreads to the female flowers.

What is the process of transferring pollen to a flower?

Pollination is the process in which the pollen is transferred to the flower for fertilization. Cross-pollination refers to plants that require the pollen of a male flower from a different plant to fertilize the female flower. In many cases, this is done by pollinating insects, such as honeybees.

Can honeybees pollinate apple trees?

Resist treating the trees with insecticides or other chemicals while the apple trees are in bloom and pollination is due to take place. Honeybees tend to be extremely sensitive to insecticides, therefore your pollination will not be as successful if these chemicals are applied.

Do honeybees pollinate?

In many cases, this is done by pollinating insects, such as honeybees. Because of this, distance between pollinators is very important. Even self-pollinating varieties will do better when cross-pollinated with another variety.

Do apples need to be pollinated?

Proper Cross-Pollination. Not every apple tree will be the best pollinator for another. For the best fruit production, a different variety of apple needs to pollinate. Even with different varieties, it is not quite as simple as planting two different varieties of apples close to each other.

Can Jonagold be pollinated?

The first thing to keep in mind is that the flowers need to be in bloom at the same time. Certain hybrid apples such as "Jonagold" are not able to pollinate others. Early bloomers include "idared," "liberty," Manchurian crabapple and "honeycrisp" varieties.

What are crabapple pollinators?

What zone do honeycrisps grow in?

The Honeycrisp prefers the cooler temperatures of USDA zones 4 through 6, but it will grow in zones 3 through 8. The Orange Pippin Fruit Trees pollination checker recommends several compatible apple trees to plant near your 'Honeycrisp.'.

What is the flowering group of Honeycrisp apples?

Cross pollination requires the bloom times of two trees to overlap. The 'Honeycrisp' apple is in flowering group 4, which means it blooms in mid to late season. Trees in flowering group 4 will overlap in bloom time, be pollinated by and help pollinate trees in groups 3, 4 and 5.

What is a honeycrisp apple?

The 'Honeycrisp' apple (Malus domestica) is a variety that was introduced into the commercial market in the 1990s. It continues to gain in popularity and retains its crispness and flavor for many months when kept in cold storage. There are over 160 viable 'Honeycrisp' pollinators, but its preference for the cool weather of U.S. Department of Agriculture plant hardiness zones 3 through 8 and use as a fresh apple, rather than a cooking apple, helps narrow down the choice of pollinators for the home garden.

Can you grow an apple tree from a crabapple tree?

If you want to grow an apple, you are going to have to plant a neighboring apple tree. (Or plant it near a wild crabapple tree. Crabapples are actually very good pollinizers). There are, however, some varieties of apple tree that are monoecious, which means only one tree is required for pollination to occur.

Can you see fruit from an apple tree?

If you plant one apple tree and there are no others around for miles, chances are you’re never going to see any fruit…usually. While rare, there are actually some apples that purportedly pollinate themselves. Keep reading to learn more about self-fruiting apple trees.

Can Apples Self-Pollinate?

Reproduction

Image
Cross pollination of apple trees must occur at bloom time wherein the pollen is transferred from the male part of the flower to the female part. Transfer of pollen from cross varieties of apple trees to alternate cross varieties is called cross pollination.

Effects

  • Although terrific fliers, honeybees tend to stay within a smaller radius of the hive when cross pollination between apple trees is occurring. Therefore, growing apple trees which are situated more than 100 feet away may not get the apple tree pollination they require.
See more on gardeningknowhow.com

Examples

  • If you are growing apples which are poor pollinators, you will need to select a cultivar that is a good pollinator. Some examples of poor pollinators are: These poor pollinators should be combined with the likes of any of the following crabapples to encourage cross pollination between apple trees:

Variations

  • Another method of encouraging apple tree pollination is grafting, wherein a good pollinator is grafted onto the top of a less pollinating variety. This is a common practice in commercial orchards. The top of every third tree in every third row will be grafted with a good apple pollinator.
See more on gardeningknowhow.com

Other uses

  • Bouquets of high pollinators with fresh, open blooms may also be hung in a bucket of water from the branches of the lesser pollinating growing apples.
See more on gardeningknowhow.com

Cultivation

  • Once good cross varieties of apple pollinators have been introduced to poor pollinators, the most crucial element of cross pollination needs to be examined. The honeybee is one of natures most industrious and necessary creatures and should be fostered to ensure that excellent pollination is achieved.
See more on gardeningknowhow.com

Benefits

  • In commercial orchards, a minimum of one hive per acre of growing apple trees is needed. In a home garden, there are usually enough wild honeybees to accomplish the pollination task, but becoming an apiarian is a rewarding and engrossing activity and would actively assist in pollination; not to mention the added benefit of some delicious honey.
