    Default Keep or Not to Keep?

    I have an oncidium that seems has this growth habit of each new growth being situated at a higher position than the previous one. That means the newest growth is now above the bark surface, and the oldest pbulb (a backbulb) is so low that it's completely under the bark mix. I didn't know that backbulb was there until I was repotting and noticed that hidden bulb. Anyways, I'm worried that the "underground" backbulb might get rotten, since there's a repotting rule about not covering bulbs. (It's been okay for several weeks since I repotted, but who knows what'll happen in the future?)

    If I leave it, will it be risky? I don't want to risk rot...But if I remove it, then the plant will have only three other bulbs and the new growth. Backbulbs reserve nutrition for the plant, I know. Well, . What do you think? Remove or not to remove?

    It sounds like it is fine. I would just keep an eye on it so that if it does start to rot, you can remove it. If it is showing no signs of rot now after several weeks, it is most likely fine like it is.

    If is ain't broke...

    Cheers!

    Hi Lily,

    I have similar issues with a Laelia anceps. I got it when it was only small and the progressive growth is higher than the previous. As I wanted to make sure that the new growths are getting enough support from older growths I just left the older p/bs on and buried them under the bark... of course I am using plain bark as a mix so it dries out fairly quickly. Anyways, it looks like I have three new growths happening and the older buried p/bs are still ok...

    So anyways, I'd say that if your mix tend to stay too wet, then it might be an idea to get rid of it, however, if the medium ur using 'dries' out fairly quickly then keep it on.

    Cheers
    Tim

    Hi Lily,

    This is my solution to 'climber' Oncidium. The mount is a bamboo and the cavity keep moisture longer than wood or other flat mount.

    I think the bark dries pretty fast, and it's in a clay pot, so I'll just leave it there. I'll keep an eye on it just in case.

    Tanya, that's a great idea! Plant looks very nice and healthy. I'm sure my onc will climb out of its pot in a while, and that gives me an idea.
