Bloom times matter more than spacing when planting to encourage cross-pollination. Plant bushes that have the same bloom time close together so their pollen will be available for bees at the same time in the growing season. ... Blueberries can only cross-pollinate within their families.

Do you need more than one blueberry bush to get berries?

Answer:Blueberry plants are self-fertile (each flower has the necessary male and female parts), however you still should buy more than one variety. That's because a blueberry plant produces more berries and bigger berries when it cross pollinates with a different blueberry variety. ... Be sure bloom times overlap.

Do you have to have 2 blueberry bushes to produce fruit?

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.
