Do blueberries need to cross pollinate to get fruit?
You do not need to cross pollinate blueberries to get fruit. A single plant will be able to produce fruit on its own. A single blueberry plant can produce fruit on its own, but will produce more with other varieties nearby. However, blueberry plants will produce more fruit with other varieties of the same type nearby.
Do blueberries pollinate without bees or wind?
Some plants can rely on the wind to help with pollination. However, the pollen from blueberry flowers is heavy, so it doesn’t travel very far on the wind. Blueberry flowers produce heavy pollen that does not travel far on the wind. With no bees or wind, blueberries will have a difficult time getting proper pollination.
How are Northern highbush blueberries pollinated?
Northern highbush blueberries ( Vaccinium corymbosum) are common throughout the northern U.S. states and Canada, and are native to eastern North America. They require pollination to ensure that flowers present at bloom turn into large, harvestable berries later in the season. Pollination is achieved by the movement of pollen by bees.
Can rabbiteye blueberries cross pollinate with other varieties?
A rabbiteye blueberry can only pollinate another rabbiteye, a highbush can only pollinate a highbush and so on. The half-high hybrids can cross-pollinate with other hybrids as well as with "pure" highbush varieties.
Do I need to plant 2 blueberry bushes?
Blueberries are partially self-fertile, so you will harvest more and larger berries by planting two or more varieties together. Planting more than one variety can also extend the harvest season.
Will a single blueberry bush produce fruit?
With just one bush and some bees, though, you'd get some fruits. It's also possible bees could bring in pollen from someone else's nearby blueberry bushes, meaning you could get a pretty decent crop with just one plant. Some varieties are more self-fertile than others.
Do I need to pollinate my blueberry bush?
Pollination is an essential component of growing blueberries. To attain high levels of fruit set with large evenly-ripening berries requires bees to deposit enough pollen on stigmas during bloom. This can be done by honey bees, other managed bees, and wild bees.
How close do blueberry bushes need to be for cross-pollination?
The hole should be no more than 5 feet from another blueberry bush; proximity is necessary for cross-pollination. If you are planting several rows of blueberries, space each bush 5 feet apart and space the rows at least 10 feet apart.

Highbush blueberry plants usually require six to eight years to reach full production and range from 5 to 8 feet high at maturity. Highbush blueberry plants usually require six to eight years to reach full production and range from 5 to 8 feet high at maturity.
What happens if blueberries don't get pollinated?
So, why does a blueberry bush flower, but not produce fruit? Lack of pollination will prevent a blueberry bush with flowers from producing fruit. Also, a blueberry bush that is too young may flower well, but not produce any fruit.
How can you tell if a blueberry is male or female?
The male flower is distinct, with four stamens around the center, while the female flower will have no stamens, but a prominent high center or pistil. Pollination also takes place in May and this is what produces the red berries in November. Another red-berried landscape plant in wide use is Taxus, or yew.
Why doesn't my blueberry bush have berries?
Blueberry plants need full sun. If not, you will be disappointed. Like most plants grown for food, the light blue berries do best in full sun (at least 6 hours). They can take some partial shade, but too much shade will decrease flowering and fruiting.
Which blueberries are self pollinating?
As a rule, Southern highbush blueberries are self-fertile. However, larger and earlier-ripening berries result if several cultivars are interplanted for cross-pollination.
Where is the best place to plant blueberry bushes?
sunny locationSelect a sunny location with well-drained soil that is free of weeds and is well-worked. It's best to locate your blueberry plants in an area where irrigation is readily available as best results will be achieved by keeping the root zone moist throughout the growing season.
Do raspberries and blueberries cross pollinate?
Berries are not that difficult to grow at all. Even if you think you cannot keep your flowers blooming, I bet you could grow berries. Blueberries, raspberries, and blackberries all benefit GREATLY from being cross pollinated.
How many blueberries will one bush produce?
Blueberry plants should come into full production by the fifth or sixth year. Gardeners can expect to harvest 5 to 10 pounds of fruit per plant from mature highbush blueberries. Half-high blueberries generally produce 1 to 3 pounds per plant....Growing Blueberries in the Home Garden.Current soil pHSandy SoilLoam Soil5.00.41.25 more rows•Mar 23, 2001

How often does a blueberry bush produce fruit?
So, when does a blueberry bush bear fruit? A blueberry bush will produce fruit between June and August, after blooming in spring and early summer. A blueberry bush will produce fruit 2 to 3 years after planting, reaching full production after 6 years and full size after 8 to 10 years.
Which blueberries are self pollinating?
As a rule, Southern highbush blueberries are self-fertile. However, larger and earlier-ripening berries result if several cultivars are interplanted for cross-pollination.
How much water do blueberries need?
Blueberries require about 1 inch of water per week to set fruit and thrive. Plant at least two blueberry varieties that bloom in each of the seasons -- early, mid-season and late -- for a prolonged harvest period during the year.
What degree does Mary Lougee have?

Do blueberries need to be pollinated?
Blueberry (Vaccinium corymbosum) bushes are self-pollinating to an extent, but grow larger fruit through cross-pollination by a second variety. Bees and wind help bushes to cross-pollinate, although the bushes need to be near each other to be productive. Both varieties of blueberries involved in cross-pollination need to have bloom times ...
Do Blueberry Bushes Attract Bees?
Blueberry bushes attract bees with their abundant flowers. According to the University of Florida Extension, these flowers attract a variety of different pollinators, including:
Do You Need to Cross Pollinate Blueberries?
You do not need to cross pollinate blueberries to get fruit. A single plant will be able to produce fruit on its own.
What is a blueberry plant?
Blueberry plants are self-pollinating (also known as self-fertile or self-fruitful). This means that each flower has both male and female parts. Blueberry plants are self-pollinating: each flower has both male and female parts. In self-pollinating plants, the male part of the flower can release pollen onto the female part of the flower.
What are the stimuli for blueberry flowers?
The stimulus could come from several things, such as: Wind. Gravity. Pollinators (such as bees, which buzz the flowers or carry pollen from flower to flower). Unfortunately, blueberry flowers will not get any help from the first two items in the list above.
Why do blueberry plants buzz?
According to North Carolina State University, the buzzing of bees (sonication) shakes pollen from the anthers of flowers. This makes it easier for bees to collect pollen and increases po llination for blueberry plants. Some plants can rely on the wind to help with pollination.
Why do blueberry bees visit my bushes?
All of these bees may visit your blueberry bushes to help with pollination. However, they can certainly vary in their efficiency.
How tall do blueberry bushes get?
Northern Highbush – these blueberry bushes are hardy to the winter cold in northern regions. They can reach heights of 6 to 7 feet at maturity.
How far apart should I plant late berries?
You will get berries regardless of weather you have another variety or not! but, you will get MORE berries with another pollinator close by, Why plant just three late berries , when you could plant one early, one mid, and one late variety, plants should be about 5-6 ft apart, you do not need a one on one ratio, but I would at least put the other one in the middle of the other two.
How far can bees travel?
That said, bees are known to travel across yards -- so it's not necessary to fuss over the distance -- I think you'll be fine with 20 ft.
Do you get more berries if you have a pollinator?
muddflapper is correct. You will get more and larger berries if you have a pollinator. I think you would be better to have an early, middle, and late producer so you don't have one huge crop all at once towards the end of the season. Why not have a steady supply of berries all season long?
Do wild berries cross pollinate?
Just be aware that with having different varieties that produce at different times...they also bloom at different times & may not cross pollinate. I have wild ones that I dug out of our woods & tame ones I bought (no idea of variety) but my wild ones are already setting berries by the time the tame ones bloom.
How many colonies per acre for blueberry?
This shows 5 hives per acre for Jersey and Earliblue, but some growers are using up to 8 colonies per acre to ensure good pollination if spring weather is cool and there are only a few good days for honey bee activity. These higher stocking densities can also be considered a form of pollination insurance, to make sure that whatever the spring brings there will be the best chance of good pollination.
How do bees release pollen?
They may release the pollen by jiggling the flower with their legs, as is the case for honey bees. Bumble bees and some other native bees are better adapted to release the pollen using a vibration behavior known as “buzz pollination”. When the bees shake the anthers the pollen collects on their bodies.
Why are some cultivars not sufficient?
For some cultivars it is not sufficient just to get high rates of pollen transfer from bees, because the type of pollen can be important. Some cultivars benefit from the transfer of cross-compatible pollen, meaning that the field should be designed to have a combination of cultivars that bloom around the same time and that are compatible. For cultivars dependent on having cross-pollination for full yields, this can provide a 10-20% increase in yield from the improved fruit set and berry size. Table 1 provides a guide to cultivars and their level of dependence on this cross pollination for full yields. However, many popular northern highbush blueberry cultivars are self-fruitful, meaning they can be fertilized by pollen from the same cultivar (High group in the table), and this is one reason why solid blocks of some cultivars can be highly productive. Other cultivars are intermediate, meaning that a benefit can be gained by interplanting with another cultivar, but for many commercial settings growers might consider the increased complications in management outweigh the benefits.
How do blueberry flowers pollinate?
Bees are responsible for this movement of pollen, so blueberry pollination depends on having enough bees active in the field during bloom to deliver pollen. Each flower must be visited once by a bumble bee or most native bees, or three times by honey bees to get enough pollen so that berries will grow to maximum size. There can be 10 million flowers per acre, so there is a lot of work for bees to do!
Why do blueberry fields need to be pollinated?
By planning ahead for how fields will be pollinated, growers can help ensure they receive the maximum return on their investments in land, bushes, and other management inputs. Given the high per-acre input costs of blueberry production, spending money to ensure high levels of pollination makes sound business sense. Other things being equal, well-pollinated fields have larger berries, higher yields, and more even ripening than fields with sub-optimal pollination.
What is the honey bee drinking from a blueberry flower?
Figure 2. A honey bee drinking nectar from a blueberry flower. This is the workhorse of blueberry pollination, and to achieve high yields the fields must be stocked with sufficient numbers of healthy colonies during bloom to ensure there are enough bees for sufficient transfer of pollen between flowers.
How many bees are in a hive?
A healthy colony contains around 30,000 worker honey bees and will have six frames of brood. Having weak hives will affect how much pollination the fields receive, so it is worth taking time to ensure you have strong hives. If you suspect weak colonies, talk to your beekeeper about getting additional hives or replacing them. One strong hive of 30,000 bees will provide better pollination than two 15,000 bee hives because there will be more worker bees that fly to visit flowers. One way for growers to ensure they receive strong colonies is to establish a pollination agreement that lays out the grower’s expectations. This can include the strength of the colonies and how quickly the colonies will be taken out of the field after bloom. Example pollination contracts are available online.
What are the berries that ripen in late spring?
The flowers appear in clusters of small, white, bell-shaped blooms in late spring, leading to deliciously edible berries that ripen from green to a deep purple-blue. Relatives within the Vaccinium genus include the bilberry, cranberry, huckleberry, and lingonberry.
Why are my blueberry leaves yellow?
But you can use any fertilizer for acid-loving plants, including blueberry food and azalea food. It’s not uncommon for blueberry leaves to begin to yellow or look chlorotic. Although this is usually a sign of iron deficiency, it is probably not caused by a lack of iron in the soil.
What is the best blueberry to grow in the winter?
For colder northern climates, these are the main varieties: Highbush (Vaccinium corymbosum) is a 6-foot shrub hardy from Zone 4 to Zone 7. This is the most common and most productive type of blueberry. Varieties good for cold winters include ‘Bluecrop’, ‘Blueray’, ‘Herbert’, ‘Jersey’, and ‘Meader’.
What is the name of the bushes that produce blueberries?
There is also a variety that produces pink blueberries, 'Pink Lemonade'. Lowbush (Vaccinium angustifolium) are bushes well suited for the coldest climates, as far north as zone 3.
How to propagate blueberries?
Like many woody shrubs, blueberries can be propagated by taking softwood cuttings and rooting them. Not only is this a cost-effective way to get a new plant, but it also helps to thin out mature plants. The best time to do this is in the early spring. Here's how: 1 Choose a healthy branch, and use pruners to cut off the last 5 inches of growth from the tip of the branch. Remove all but the top two or three leaves. 2 Apply a rooting hormone to the cut end. 3 Plant the cutting in a moistened soilless potting mix in a small container. 4 Keep the container in bright, indirect light, and make sure the growing medium stays moist but not soggy. It can take a few months for the cutting to root. One new leaves have developed and you feel resistance when you gently tug on the cutting, it is ready to be planted in the garden.
How many types of blueberry plants are there?
There are four main types of blueberry plants: highbush, lowbush, half-high, and rabbiteye. They are primarily classified by their size, and plant breeders continue to cultivate new varieties to improve their vigor. The main types include:
How much sun does a blueberry plant need?
Blueberry plants need full sun to grow and fruit well. This means at least six hours of direct sunlight on most days.
How tall do highbush blueberries grow?
Northern Highbush blueberries grow in cold climates, tough enough to survive as far north as Canada. They grow 6 to 9 feet tall, self-pollinate, but produce a better, bigger crop if they cross-pollinate with another type. Popular cultivars, arranged by bloom time, include early-blooming “Earliblue” and ”Collins;” mid-season blooming “Blueray,” “Bluecrop,” and “Berkeley;” and late-blooming “Jersey” and “Patriot.”
What is Southern Highbush?
Southern Highbush is a cross between Highbush and Rabbiteye. They grow 6 to 8 feet tall, and while they self-pollinate, they make better berries with a buddy. Cultivars include early-blooming “Oneal” and “Southblue;” and mid-season blooming “Jubilee” and “Sunshine Blue.”
How to encourage blueberry bushes to share their genes?
You can encourage your blueberry bushes to share their good genes by picking the right varieties and planting them so that bees and breezes can work their pollen-moving magic. Here’s what you need to know.
Where do rabbiteye blueberries grow?
Rabbiteye blueberries are native to the Southeastern United States. They grow from 6 to 10 feet tall and cannot fertilize themselves.
How to get a great blueberry crop?
The secret to a great blueberry crop is picking and placing the right types so they’ll cross-pollinate.
What is cross pollination?
If you slept through high school biology class, cross-pollination is when pollen from the male parts of one plant mixes with female parts of another plant. The pollen is moved by insects and wind. Mixing up the gene pool via pollen results in larger, better and more fruit.
Can rabbiteye blueberries cross with Southern Highbush?
Remember, don’t mix types. Blueberries can only cross-pollinate within their families. So a rabbiteye blueberry can’t cross with a Southern Highbush. There’s only so much trait-mixing that can happen in blueberry land, people.
