    Yay!

    I repotted her yesterday when I got home from work. There wasn't a bad root in the bunch! But the potting mix was slightly spongey and had some white stuff on a lot of the more centrally located clumps... hard to say if it was a mold or excessive fertilizer buildup (I lean more towards the latter).

    I probably would have just left it be for a few months except that the 8" seedling Phrag Barbara LeAnn I got had a centipede chilling in the mix, which still grosses me out to remember.

    Default Mom's Onc spots

    My mom just received an Onc Ruffles on Thursday. Fed Ex where she is has no idea how to treat live orchids and has a bad habit of delivering roasted orchids. All orchids were wrapped in plastic bags (ugh) as well as newspaper.. but she tells me she poured about 1 tbsp of condensation water from the bag. Now she has leaf spotting that looks different than what I've seen on my onc leaves.

    She's asked me to post these pics to see if anyone here thinks this may be an active infection of some kind (maybe fungal?) and if so, what she should do about it? From what she's told me the spots don't go all the way through the leaves yet. She has some pbulbs starting to brown out on the same plant and the leaves on those pbulbs are, of course, turning yellow. I'm guessing that's from heat damage. She has contacted the vendor, but they haven't mentioned what to do about the spotting. Help, please?

    Hmmm -- sounds like one of you experts could easily take this thread and convert it with a little effort into an entry for this month's contest. Not that I'm plugging it or anything . . .

    I've had spotting like this occur even without leaves getting wet. But as had been said several times already .... it's harmless and Sharry Baby seems to be very prone to such spotting.

    That sounds like a pretty crappy packaging job to me. Damage-wise, looks like bacteria or fungal spot damage to me. Hopefully soon someone else will chime in to refine a diagnosis. I'd recommend treating with a systemic fungicide/bacteriacide [I've used Bayer's products for Roses with no ill effects on the plants]. A spray with Physan might also work [believe it is also called RD-20]. Note:the damage will not "heal" -- those leaves will not return to an unblemished state. The spotty areas will likely brown out or turn to black spots. It should not be a "life threatening" situation now that the plants are no longer bagged with excessive moisture.

    We were wondering if it might be contagious? I had her separate the plant from the rest of her orchids as a precaution. The vendor came back and told her there was "nothing wrong" with the brown roots and that it was perfectly healthy - the plants look great.....

    shaydra-as far as the sherry baby goes, that is the name of the game with that plant. i have been growing thousands of them for the past few years and everybody i know as well. they are notorious for having that spotting. it is maybe some flaw of so much cloning? but that plant is "bulletproof" and a great bloomer..
    as far as that second plant thats crazy they had it in a plastic bag!! that is the worst idea ive ever heard of! it looks like the super humid and dark conditions have brought on a fungal disease of some sort. it almost looks like a bacteria tho. anyhow, when the lesions like we call them are "wet" like that, definitley get the plant away from others. spores can spread very easily to other plants. use a good fungicide/bactericide if you have one.

    On last report, my mom said that the spots weren't getting any bigger or any worse, so she may be in the clear on those.

    However, she's losing leaves on the browning pbulbs (top-down blotching-browning and its progressing) and the vendor came back and told her the plants looked great and that the browning was normal and was just dye from the media.... Uh huh....

    As far as my Sharry Baby goes, I only used this post for my mom's onc. My Sharry Baby is happy and starting to bloom now... althought I don't think it smells quite like chocolate.

    Not to change the subject (PLANT) I have a Cattleya with spots, too! So do I have a problem or are these just something about this species? The plant is otherwise very healthy and putting out new growth as I write.

    looks like maybe some sort of virus. very common on Cattleyas these days. Virused plants shouldn't, technically, be that much to worry about, just don't ever cut, snap, twist, pull, brake.... anything off of that plant without using a sterilzed tool (bleach on a knife/scissors works fine). that is the only way to spread virus to your other plants. we have quite a few OLD virused cattleyas on our bench at the farm and they grow just fine like the others its just that every now and then some cultural reason or something sets on some spots or something weird.. just keep it away from your other plants...

    who knows i could be wrong and its old bacteria.. cant tell
