thanks for that, Cathy. But does a fusarium infestation move from plant to plant? Because in my situation, it only happens to some ascocendas and a few semi-strap vandas and over a long period of time. I mean in a year, it never occurs to more than two plants. And of course I haven't introduced any intervention. All my orchids are planted very close together but I didn't notice the situation being passed from one orchid to the next. All were isolated cases.
