Answer: It's difficult to diagnose a problem without actually seeing it, but the most common cause of trunk decay is due overly wet conditions. The trunk of your palm is covered in what is basically dead wood. If it is allowed to remain wet and is unprotected, it will begin to decay and become a food source for fungi. You can adjust the watering which will allow the wood to dry out, but this won't repair the damage. It may, however, allow the palm to recover. I hope so!
