Buds and flowers are always brown

I have a white mandevilla plant and was wondering why the buds and flowers are turning brown. Have always had mandevillas on my deck and have never had this problem before. Thanks

This is a common issue with potassium and phosphorus deficiencies. Are there any other symptoms, or just this? If there are other symptoms, then it may be a fungal/bacterial issue in the soil. If the leaves appear healthy, then a dose of fertilizer made for mandevillas will correct this.
