Do I need 2 blueberry bushes to get blueberries?

Answer 1

It's common practice to plant at least two different varieties to ensure good cross-pollination. Many modern varieties like Blueray, Earliblue, Bluecrop, are self-fertile & need only one plant to set fruit.

"Cultivated berries are self fertile. However, if you want a long harvest season, plant 2 or 3 varieties ripening in succession. Experiments indicate berries may be larger and slightly earlier- maturing when cross-pollination does occur."

This site says: "Blueberries are partially self-fertile, which means they bear some fruit without cross-pollination. But when at least two different varieties grow near each other, yield is higher and fruits are larger." http://rds.yahoo.com/_ylt=A0geu5Us3bVGaQkB7jxXNyoA;_ylu=X3oDMTE5NjAzZjM5BHNlYwNzcgRwb3MDMwRjb2xvA2FjMgR2dGlkA0Y5MTlfMTAxBGwDV1Mx/SIG=1262udgme/EXP=1186410156/**http%3a//www.doityourself.com/stry/blueberryprescrip

"Northern Highbush blueberries are self-fertile; Southern Highbush blueberries will produce better crops if more than one variety is planted."
