    Default Onc. Shelob- brown on pseudobulbs

    Hi all,
    I joined this forum on the suggestion of my mom, Carolla.
    I have an oncidium or oncidium hybrid called Shelob that did extremely well for me last year and flowered in June/July. It has two 'branches' which both spiked and both began to produce new psuedobulbs. Then at some point I realized that the psuedobulbs had basically quit growing - my guess given my habits is that I underwatered at a time when it needed more. They haven't noticeably changed in a few months although I think the smaller one is still producing new roots. I repotted it at the end of january and the roots seemed fairly decent at the time (plump and cream to brown colored with no sliminess or noticeable decay), still has not changed much, I'm not sure I should have repotted it.
    Anyway I noticed this week some off colors on the older bulbs.

    I was wondering if this was just age or a sign of a problem. I previously lost a wildcat oncidium after a long and drawn out process to some kind of brown rot so I am kind of paranoid!

    Thanks for any advice.

    It's thirsty. How often do you water? What media did you repot it in? What are your growing conditions? (Temperature and humidity)

    Shriveled pseudo bulbs indicate under watering or damaged roots. Since your roots are ok I would suspect the former. How are you watering? Take the plant to the sink and water copiously. Allow the plant to approach dryness before watering again. It is natural for some old pseudo bulbs to turn brown and die--but not many at once. This also could be indicative of under watering.

    As for growing conditions - I honestly don't even have a thermometer in this house, much less a hygrometer. We tend to keep the house a little cooler than most people prefer, so general household temperature is probably in the high 60s, and after doing some quick checks on my weather website average monthly humidity around here is typically high 50s-high 70s (down to a minimum of 15-20%, but that's again outside). My plants are grown in an east facing window that is not shaded most of the day except by the house and I keep them in damp trays of gravel (which I am guilty of sometimes allowing to dry out.) Depending on how much of a hurry I am in and how desperate my plants are when I finally connect the dots to water them, MOST of the time I will put the orchids in a bucket in the sink and run water over them then let them sit in it for a couple hours before picking them up, letting water drain off and putting them back in their trays. Sometimes I just pour water over the top but when I do that I try to give them a nice soaking soon afterward. Also recently since I picked up a clearance orchid with a keiki (odcdm st anthony of egypt) I have been misting the oncidiums once in a while (probably every day or two, daily if i remember). Mostly I think I don't water often enough because I really don't know how long it is between waterings... going to try to remember to start marking on my calendar to keep track. Its probably about a week and a half between waterings most of the time.

    Oncidiums have a great way of telling you when they're thirsty. Your pseudobulbs should never look "wrinkly", but full and smooth. I often will re-pot when a plant looks like this. Clean away the brown, dry areas. Sprinkle some cinnamon on the areas that you cut and put it into some new medium.
