    Default Ohhh shoot.... fungus or something!

    Didn't think it would happen to me.... I was showing off my plants today and from across the room I saw a huge black spot covering the whole leaf of one of my Blc. orchids. It's BIG and it just happened because I didn't notice a thing when I watered them last...
    On closer inspection, it seems to have black down into the bulb of another one. The leaf is dark black but still the same texture as it was - perfectly smooth - no indents or rot. But it's extremely black for about the top 2 inches of the leaf...
    I moved it away from the other orchids anyway... so odd..... it's one of the ones I bought from the NYC show...

    Kirstie,

    Post a photo if you can. That's the easiest way for us to tell what's going on.

    here it is...



    I've kept it far away from the rest, but the black is spreading. It was a cheap orchid from the NYC show, and a mistake at that, but I still do not want this problem. It could have happened to one of my good ones.

    I wonder what it is, and what caused it.... if it came from the seller or happened because of my care / mistakes, or something in my house or....

    If anyone can help me with any info, I'd appreciate it.

    Hi Kirstie,

    The image didn't appear. There's a photobucket.com message that the image is no longer there.

    It might got crown rot, one of the most dreaded diseases in orchids. Pull the plant out of the pot and inspect the roots and the crown. If the crown is all black, well, it goes to the trash can asap!

    Default Sunburn?

    I don't know about crown rot..it looks like a cattleya type to me..

    I would say too much sun on this leaf. Or too much sun and not enough air circulation. I left an orchid in a plastic sack in my car for a couple of hours last summer when it was 90+ and this was the same kind of damage that I got...except it covered the entire plant! Boy was I upset!

    So if Clint said is true, the plant was cooked! Either way, it goes to the trash can asap!

    as the left is also yellowing I would say remove the entyre leaf with a sharp knife or sissors and then treat the plant with a fungacide..It also apears that that plant is planted abit too deep in that mix
