Blueberries thrive in the same conditions that suit Rhododendrons and Azaleas with the exception that they prefer full sun. Plant Blueberries in locations with moist, but well drained, acidic soils. They prefer regular watering. Too much fluctuation between dry and wet soil is the worst thing for blueberries. They are shallow rooted and dislike excessive cultivation near their roots. Blueberries will also benefit from an application of mulch to protect and cool roots.
Blueberry plants are partially self-fertile. They will produce some fruit on their own, but you will find you'll get more berries if you plant more plants in the area.
Apply an acidic fertilizer in early spring. A Rhododendron or Azalea food is a great option as is a Fruit Tree or Berry food.
