Phal in distress (mold)
I have had this Phal for about a year and a half. I bought it in bloom, the last flower fell off about four months later, and I cut down the spikes. Ever since then I've been keeping it in a south-facing window and watering about once a week.
The newest two leaves look good - shiny and yellow-green. The bottom three are duller and matte. Yesterday I cut off a fourth bottom leaf that had turned completely yellow (you can see the base of this leaf around the pic with the new spike (?) growth), and noticed that there was a collection of mold at the base.
Is mold a death-knell? This plant has been looking pretty lackluster for a while, and the yellow leaf concerned me too. Any thoughts on next steps?
