Answer: Sounds like it needs fertilizer. However, Nitrogen encourages leafy growth, often at the expense of flowers and fruit. Select a fruit tree specific fertilizer, or use a fertilizer that promotes bloom, such as "0-10-10" or "15-30-15." The numbers represent the amount of nitrogen, phosphorus and potassium contained by the fertilizer. Berry production does vary each year due in to weather conditions. When blooming, I would recommend fertilizing it with 0-10-10 fertilizer.
