I have a large Pathos hanging in my home. I've had it for several years, always in the same place. In fact I've had Pathos plants hanging in that spot for 20 years. Usually they do very well for 5 or
6 years and then I have to dump them. I think they need to be repotted but the spot cannot take anything larger.The one I have now is only a couple of years old. All of a sudden the leaves are wilting and losing their beautiful green and white colors. The green is become faded and in general the plant looks sick.
I've taken a close look and do not see anything on or under the leaves such as ayphids. I also checked for spider mites and can't find anything. This is the first Pathos I've had where the entire plant is going at the same time.
What diseases and pests are these plants prone to? It does not need to be repotted.
Help!
thanks
