Hello, this problem occurred a while ago, but I am still dealing with it and never got a satisfactory answer...
Long story short, I have a propetallum mathina and a zygonisia cynosure. They both got something that essentially resulted in THIS:
The propetallum is most likely on death's doorstep... the new growth it had rotted away at the base as did one of it's p-bulbs... I've sprayed the plants with green earth fungicide and sequestered them...
The zygonisia has a lot of spots on it but I think it might pull through... can anyone help me out at all?
Any ideas?
