We bought a Bird of Paradise plant over a month ago and while dusting it the other day, I noticed that beneath the leaves were mold. Upon closer inspection, the talks of the plant was affected as well. I know that fungus is most likely due to misting it and not having enough air flow. My question is, what can I do to ensure its survival? I've removed the highly infected leaves and have cut off portion of the stalks that have really bad mold. The base of the plant is purple and I can tell its caused by the mold. I've applied some neem oil on the plant. I'm really concerned about the base of the stalks and how they're purple instead of green.
