Hi! I can't post a photo- because my son is not available right now to help me! I have adopted several orchids from November on-- One..( the one in my avatar) Is sick!! I think it might be Black rot fungus. I haven't over-watered it- but, when I got it, the column had a black spot on the tip when it opened. The sheif turned black, and now the leaves are turning a slight purple underneath. I have removed the plant from the others, because I have several new plants that I am nurturing along.( I don't want to spread any nasty stuff!) All of my other plants are doing well- If it's a virus, I'll destroy it... The leaves have a light mottling to them now, - They didn't have it before! I wish I could display photos! Thanks for your advice!
I can see the black spot in the photo now! I didn't know any better when I started!
