Blueberries are sensitive to the nutrients in the ground, and it is possible to overfertilize them. Applying fertilizer twice per year provides all the nutrients these plants need to produce an abundant crop. They do well with a product developed for use with rhododendrons or azaleas.
Blueberries need a fertilizer that is high in acid. Fertilizers that are high in acid contain ammonium nitrate, ammonium sulfate or sulfur-coated urea. Calcium nitrate- or chloride-containing fertilizers can kill blueberry plants.
To fertilize berries, test the soil beforehand to make sure the pH and nutrient mix is correct. Blueberries thrive in acidic soil with a pH between 4.09 and 5, and they are sensitive to over-fertilization. When the soil is adjusted to a lower pH, use high-acid fertilizers that contain ammonium nitra
