drdawg: Is it possible for long fiber sphagnum moss to transfer fungus to a staghorn? The newest fern has developed Rhizoctonia at some point. It was really overwatered when I bought it, but I didn't notice the spots until today when I moved it- they were on the bottom leaves which are very dark anyway. So, it's here now and I need to keep it drier obviously, but I thought I would ask the question.
