    Question Black Spots

    Hi dear community,

    As I read more about orchids I realized that those black spots are not normal for an orchid? I have these spots on two of my colmanara's. I do not want to loose them, any advice for me?

    I had a Phal that lived with spots just like that for a long time. All the old growth was affected. Suddenly it developed an advanced fungal infection that tried to take over the whole plant. I had to isolate and prune the poor thing pretty drastically. I am not sure how the plant's current situation is connected to the black spots, but I can't help but think they are linked. I suspect the plant had been living with a fungal infection that only presented itself as those spots, but when the plant had an unusual amount of stress (switching it to S/H medium) it responded by allowing the fungal infection to take over.

    This is just my suspicion about what my plant had and gone through, but those spots look VERY familiar to me.

    Good luck, I hope this helps some

    Not sure that it is a problem.
    Some Oncids do get small spots(notably Sharry Baby) , i,ve give up worrying.If they grow & flower fine i ignore them.
    Maybe not the best way but short of getting the plant tested(which doesn,t seem that reliable) it is very difficult to say for sure.

    Well, I bought one in bloom and other in buds with that spots. After the end of blooming I repotted them because the old pot was really small and bark seemed bad to me. Both has excellent roots without any bad sings. I made some root pruning and removed dead ones. Both doing fine but I'm really stressed. I increased somewhat low ventilation and talking them with my warmest tone

    Hi , I don't think you have a problem, the spots are not the same as the ones in another posted picture , some of the intergenitics are prone to what we call freckles . Gin

    I agree with Gin. I only have a couple Onc/Intergenics, but 2 of them have freckles like that, and so far they have been fine! But keep thinking good thoughts!

    Yours look okay. All Sharry Babies I've seen have freckles, which is "normal". So do some other oncidiums. They're normal as long as the spots are little black dots, not some ugly combination of dots and patches and speckles like the pic I posted in the other thread. From the pictures I can see you're fine...no worries .

    I once got worried about spots too...the wilsonara orchid had similar spots as yours. Here's a pic from a long time ago.
