I've had this low-maintenance hanging palm plant for years. It has done very well! Over the last month it's suddenly taken a turn for the worse. All of the fronds appear to be drying out and I think they're dying, turning from yellow to brown. I have not changed anything in the way I care for it or its location. Do these photos help identify what's wrong? I've always had it in one of those "self-watering" hanging pots with a reservoir of water that collects on the bottom that then wicks up to water the roots via a built-in piece of fabric. Does that wicking fabric have a finite lifespan? Maybe it eventually gets clogged with minerals and debris and stops working? I have also never really changed the soil (does its nutrients ever get exhausted)? Thanks in advance for your anyone's advice.
