This has just a few likely causes. It could be that there is too much Nitrogen in the soil, or the opposite. That there could be a lack of phosphorus in the soil. If you feed the tree once or twice a year and do not expect it to be a nutrient deficiency, then I would suspect that the soil pH is off. You can take a sample of the soil to your local extension service, and they will be able to test your soil and tell you if anything is off with it.
