|What can I do?|
I can't determine the problem with that description alone. I suggest you take a frond and a photo of the plant to your County Extension Office for them to look over and diagnose. Depending on what they find they can prescribe an appropriate remedy. Their contact info is:
250 West County Home Road
Sanford, FL 32773
Phone: (407) 665-5551
Thanks for the question. Please stop in again soon!
