| Odontoglussum and Paph problems
Hello,
This is my first forum thread, and I doubt I will get all the info in my first post, so feel free to ask for more info/pictures!
First orchid:
I have an Odontoglossum orchid with what seemingly has a fungus infection. It has tiny brown spots on the leaves (see pictures), and from the pictures that Ron posted in the “Webpage;How to identify Orchid viruses in orchids” thread, I think it is Cymbidium Mosaic Virus, but I could be wrong. If it is indeed a fungal infection, how do I treat it? The advice I read online says I should cut off all diseased leaves, but there are so many of them that if I cut them all off, there would be none left! This is my first encounter with a fungal infection of any sort, so I do not own any fungicide and would rather not have to buy one…are there any household items that can treat fungal infections?
This poor orchid also desperately needs a repot/divide, so when should I do that? I was holding out until it lost its blooms, but now with the fungal infection, should I treat before I repot or after?
Second orchid:
My second orchid in distress is my Paph, which I think is suffering from crown rot. However, I have never seen this either, so any clarification is welcome. I recently noticed that where the leaves met at the crown, they were rippley and streaked with red, which was very different from my other Paph which is healthy. Then, one of the bottom leaves suddenly turned yellow with black spots, which nearly scared me to death…and by the next morning it had turned black (see pictures). Surprisingly, the plant has new shoots and is still in bloom, and there is another bud on the spike, so I am hoping I can save it! For the time being I have sprinkled cinnamon on the crown, but I don’t know if that is helping at all...
Both my orchids are also quarantined.
So I guess my questions are:
1. Does my Odontoglossum orchid have a fungal infection?
2. If so, how should I treat it?
3. If I need to treat it, should I treat it before or after I repot/divide it?
1. Does my Paph have crown rot?
2. How should I treat it if it does?
So sorry for the long post! As a beginner orchid grower it's a relief to be able to ask questions like these to other more experienced growers!
