| Check the root system. The roots will begin rotting away before the leaves show the after effects. My guess is that you are either over watering or the media has broken down and is holding water too long. Normal phal behavior is for the bottom leaf to slowly turn yellow and slough off while the others remain totally normal - usually about two per year. What kind of media are you using and how often do you water? Have you repotted it or is it the original media and how long have you owned the plant? Just a few questions that might help answer. Roots should all be thick and firm - a light grey/tan color with green (sometimes reddish green) tips is normal. |
