    Default oncidium watering

    I have an Oncidium "Sharry Baby" that I acquired last month and I need some advice, since it is my first oncidium. Nothing is wrong with orchid right now but I'd like to know how often I should be watering it. Should the medium completely dry out between waterings, or should it be kept moist all the time? Also, would it be beneficial to put it into a translucent orchid container, for the simple reason of monitoring moisture levels throughout the whole medium? Or would the roots be too sensitive to light? Any advice would be helpful. Thanks!

    You should let your Sharry Baby's medium dry out between waterings. I don't think the roots would mind being in a clear pot. They grow aerial roots all the time.

    Here is a copy/past from the RVO care page regarding oncidiums for some extra information. Good luck!

    Oncidiums
    Light Requirements:

    1500 - 2000 footcandles

    A bright kitchen window with no direct sun is perfect for these medium-light loving lants.
    Temperature:

    70 - 90 degrees F. daytime, 60 - 65 degrees F. night.
    Humidity:

    40 - 65 % relative humidity is ideal.
    Notes:

    In general, Oncidiums and the intergeneric hybrids produced with them form sprays sometimes over four feet long of tiny, often yellow or pink-tinted flowers that can make quite a show. Almost all are fragrant. They grow quickly, and it is not unusual for new pseudobulbs to stair-step their way out of a pot, throwing thin roots everywhere. These can be misted with fertilizer solution diluted from 1/3 to 1/2 strength each time the pot is watered. Oncidiinae appreciate good air movement. Plants that receive sufficient light to flower often exhibit scores of tiny brown spots on the leaves and their leaf-tips frequently turn yellow. The leaves themselves can be quite brittle and will split naturally during normal growth, so the foliage is usually not considered particularly attractive. Equitant oncidiums can be difficult, as they require a cool spell at the end of the growing season to initiate the next years flowering.

    Cheers,
    BD

    Good point. The leaves really do always look like crap. Especially when they grow up and hit your lights....

    I LOVE Oncs.! I grow them in LFS and they love it. I let the moss go nearly dry before watering again. My leaves look just fine. I have a few Equitants (Carnival costume) that look just fine and have been blooming for the past 2 months. My Sharry baby looks fine too although not in bloom right now. She's in bark but I'll probably switch her to LFS this spring.

    Speaking of Sherry Baby, Mine is out of control huge! It is spiking now but if I repot it should I try dividing it or just transferring to a large pot?

    Yeah, yeah ,yeah....in my house oncid's shiver in fear. For some reason, bringing one here is almost certainly a death sentence. Sometimes they grow, but then sooner or later they croak on me. During my recovery, all my volunteer helpers never showed, so i lostmy baby mule-ear oncids i've babied along for a year.

    I always thought Oncidiums and Alliance-like to be thirsty drinkers. That there roots didn't like to dry out or you'd get an "accordian" pattern effect in the leaves from dehydration.

    I'm w/ you,Connie. Oncs are a royal pain for me. I rarely have any success with them.
