Blueberries are delicious and healthy. But how do they grow? Many gardeners wonder how blueberries get pollinated. Let’s find out!
Blueberry Pollination: The Basics
Blueberry plants need pollination to produce fruit. This happens when pollen moves from one part of the flower to another. While the wind can help, bees are the main pollinators.
Blueberry flowers are small, bell-shaped, and face downward. Their pollen is heavy and sticky, so the wind can’t move it well. That’s why bees are so important.
The number of seeds inside a blueberry affects its size. More seeds mean bigger berries. Good pollination helps produce the best fruit.
Bees use “buzz pollination” to collect pollen. They vibrate their bodies or tap the flower to release pollen, just like shaking salt from a shaker. This makes pollination more effective.
Different bees help pollinate blueberries. Honeybees, bumblebees, and native bees all play a role. In the southeastern U.S., a native bee called the southeastern blueberry bee (Habropoda laboriosa) is especially helpful.
Types of Blueberry Varieties
Blueberries come in different types, and each has unique pollination needs. Here are the main ones:
- Highbush: The most common type. They can self-pollinate but do better with another variety nearby. Examples: Bluecrop, Blueray, Duke.
- Southern Highbush: A hybrid that grows well in warm climates. Examples: Misty, O’Neal, Sharpblue.
- Rabbiteye: Grows well in hot, dry areas. Needs cross-pollination. Examples: Brightwell, Climax, Tifblue.
- Lowbush: Wild blueberries that need cross-pollination. Examples: Brunswick, Fundy, Top Hat.
- Half-High: A mix of highbush and lowbush. Cold-hardy. Examples: Northblue, Northcountry, Polaris.
Are Blueberry Plants Self-Pollinating?
Some blueberries can self-pollinate, meaning they don’t need pollen from another plant. However, many do better with cross-pollination. This happens when pollen from one variety reaches another.
Self-Pollinating Varieties
Northern Highbush blueberries can self-pollinate. But they still produce more fruit with cross-pollination. Examples:
- Bluecrop
- Bluegold
- Blueray
- Duke
- Elliott
Varieties That Need Cross-Pollination
Rabbiteye and Lowbush blueberries must have pollen from a different variety to produce fruit. Examples:
- Brightwell
- Climax
- Powderblue
- Premier
- Tifblue
How to Improve Blueberry Pollination
Want more blueberries? Try these tips:
Plant Multiple Varieties
Even self-pollinating types do better with another variety nearby.
Attract Pollinators
Bees help blueberries grow! You can attract them by:
- Planting flowers for extra nectar.
- Avoiding harmful pesticides.
- Providing places for bees to nest.
Optimize Planting Design
Plant blueberries in rows to make pollination easier. Space them out so bees can move around freely. If your blueberries need cross-pollination, mix different varieties.
Conclusion
Pollination is key to a great blueberry harvest. Some varieties can self-pollinate, but most do better with another variety nearby. By planting different types and attracting bees, you’ll get the best results from your blueberry plants!
