    Default black speckles?

    Just got my Onc. Sharry Baby 'Sweet Fragrance' today. Nice, BIG, plant... they warned me when I ordered that it had some speckling on the leaves, but that it wasn't sick - just old damage. I just want to double check here so I don't accidentally spread something to my other babies.

    I can post pics later.

    A few of the leaves have what I would describe as small black freckles on the top 1/3 of the leaves. The spots are totally level with the healthy part of the leaf around it. 1 or 2 of the leaves also have a slightly yellowed tip as well as the speckles. The spots are about standard freckle-sized and spaced about like... if you sneezed from a foot or so away. (I know, ewwww.) Is this a water / fertilizer issue? What would cause something like this?

    I searched but didn't come up with anything that sounded like my ailment (but I might have missed it).

    Thanks!

    Not an ailment actually. Oncidiums like this one need high light levels to bloom. When they get enough light to bloom, they usually get these spots. It is normal. Unless yours has something different than what is common, don't worry. I think the spotting is a form of virus, but it is always there and it seems harmless enough.

    Cheers,

    Default Spots on Oncs...

    The spotting on Onc. leaves is actually from a secondary FUNGAL infection (no virus here) that happens most often when the leaves are wet and exposed to bright light. I can't stress the importance of dry leaves enough--all of my orchids only get a "bath" about twice a year.



    Like BD said, nothing to worry about...

    Thanks for clearing that up. I know it is very common.

    Cheers,

    Whew. Good to know. I got it from a highly reputable GH, so it wasn't so much a distrust as a double check.

    So probably an old fungal infection, then? I'll make sure to take extra care to keep the leaves dry in the future. I usually have to wipe down any of my leaves where water has dried anyway because of a decently high calcium or lime content, so in general I try to keep water off leaves to avoid the hassle.

    Sharry Baby, IME, is extremely prone to such spotting. But as others have said, nothing to worry about

    I haven't photo'd the spots since it seems to be a pretty benign issue, however, I could throw something up here just for future searchers inquiring about the same issue....

    BTW, my Sharry Baby is HUGE... LOL! I can't wait to get some blooms on these spikes....

    Default As promised...

    As promised, here are what the speckles in question look like just for future reference...



    Oh and is it normal for to see a new growth in the very center of the plant like the second photo shows??? ... The 3rd photo is the whole plant... (To give an idea of size, thats a 27" TV it's sitting on top of and its in a 6.5" pot.... And the spike is 28" long from the pbulb to tip)

    That is a spotty Muldoon! But From being paranoid about every little spot, I am now quite laid back, viruses usually have yellow leaves and look far more malevolent. Lets wait for the photos! Judi

    It's really nice and healthy looking. New growth can come from anywhere on the side of any p-bulb...perfectly normal as well.

    Again, normal spotting of the leaves...keep them dry and just water the roots!
