How to Pollinate Blueberries

Plant more than one variety of blueberries. The fruit has male and female organs but is not self-pollinating. Different varieties must be planted in close proximity to each other to attract bees.

Plant varieties that grow well in your region and climate. Opt for those that become ripe at different times, for continuous fruit. If the blueberries are to be used for baking, plant varieties with smaller fruits such as rancocas or little giant. For eating, grow larger fruits such as brigitta or chandler blueberries.

Plant two blueberry bushes for each family member to ensure an adequate amount of fruit.

Place two different varieties within 100 feet of each other for cross-pollination. Space each blueberry plant 2-1/2 to 6 feet apart, depending on the desired appearance.

Spread 2 to 4 inches of mulch around each plant to reduce weeds, conserve soil moisture and promote strong growth.

Prune blueberries heavily in the early spring to promote strong fruit growth. Bluberry bushes should be narrow at the bottom, open at the center and free of crossing and rubbing branches. Use hand pruners, loppers or a handsaw to remove all but three main stems in the first two years of growth. After that, cut off diseased and broken canes as they appear. Remove branches that touch each other, to improve air circulation. Trim off no more than three mature canes each year.

Expect to see bees traveling between the blueberry plants. Southeastern blueberry bees are effective pollinators of rabbiteye and highbush blueberries. They are out in full force at the height of blooming time. Bumble bees also are active in blueberry fields, working in the early morning hours.
