I live in West Palm Beach Fl and I have 4 Chinese Fan Palms that seem to be dying within the past 2 weeks. The 30' trees were planted in April of 2007. They were fertilized on 04/09/2009 and get plenty of water. The palm fronds are dry and brown, on the part that turns down and the remaining fronds is green with bright round orangy yellow spots (circles). I'm looking at them with binaculars and they look odd. Anyone have any suggestions? I can't afford to loose them. Candace
