DaisyI said:Are the yellow spots on the old leaves only? If it was a virus, wouldn't the entire plant be affected, including flowers? Isolate it and see what develops, if anything. Use your sanitary practices (but you should use those as a matter of course).

If it is a virus, its not in the potting medium but in the plant tissue. Virus are spread by vectors in an exchange of bodily fluids - the same way we get viruses. That could be an insect but most likely a human. Wear disposable gloves and sterilize surfaces and tools between cuts and plants. A 10% bleach solution will kill the virus too, but it sure plays havic with your gardening tools.

The spots are both in old leaves and new leaves. The older leaves look the worse though. The plant hasn't flowered since I discovered these spots but it is growing little branches now and seems that it may want to flower at some point. I'm curious to see what the flowers will look like if it gets to bloom to see if they look different than before.

I would like to keep the orchid if I can since it was my first one and a gift from a very dear friend. I fear for my other orchids though if it is indeed a virus. I have kept it separated from the others once I found the spots and sterilizing everything with alcohol to try to prevent more propagation of whatever these spots may be.
