Answer: If you see no insects on the plant, I suspect the problem is related to either sun exposure or soil conditions. Angel's trumpets (Brugmansia sp.) are sun-loving, fast-growing plants. In the Lower South, they appreciate light afternoon shade, while in the Middle and Upper South, they welcome all of summer's warmth. Angel's trumpets need well-drained soil; when growing one in a pot, make sure the container has a large hole in the bottom to allow easy water passage. The growth rate is rapid, so plenty of water and fertilizer are necessary to keep these plants vigorous and blooming. Brugmansias are heavy feeders, and a liquid, blossom-boosting fertilizer such as 15-30-15 or 10-50-10 keeps them producing flowers. Apply every 2-3 weeks and you should see an improvement in your plant.
