    Default Sick Miltonia - Strange symptoms

    Hi Everyone,

    This miltonia is one of the orchids that Katie (aka Desertgal) gave me.
    It appears to be suffering from some kind of rot that I have not seen before.

    The problem starts at the base of the pseudobulb and then progresses upwards and throughout the leaves.

    The usual rot that I encounter with orchids would cause the orchid tissue to turn black/dark purple and soggy. This one has a bright orange/light brown tint to it.
    Could this be from dehydration? This plant is watered at the same time as the other oncidiums in the bench and this is the only one displaying these symptoms.

    Any ideas?

    Thanks,
    John

    Hmm. Roots look healthy (though crowded)... Potting media looks like its getting close to needing a change... I'm not all that experienced and don't have any Milts myself....

    Not really sure but.... Could it be bulb rot?

    Hi John,

    Looks like water settled in between the growths of the plant and caused it to rot. The roots look good in the photo, so this is fairly new. I would cut away the rotted material and see if you can save the remaining part of the plant. When watering it, try to do it at the potting medium level and avoid getting the leaves wet until it gets well. I suspect this happened because it was so root bound in the pot, the water did not drain off of the plant and that caused the rot.

    Of course I could be totally wrong, but that would be my guess from the photos.

    Cheers,
    BD

    My guess with these hateful plants is that the temps (especially night temps) are too high.

    Miltioniopsis (which is what you have..completely different from miltonia) are cloud forest orchids that do best in temps ranging from 60-80. High temps can be handled for short periods of time, especially if night time temps are cool and humidity is high.

    High temps cause these HATEFUL plants to rot. I couldn't grow them until I put them in the most humid microclimate in my growing area with temps from 62-82 every day (winter temps can be a few degrees lower).

    The first one I got I put outside in our summer (75-95 temps) and it succumbed just like your plant is starting to.

    These are not the easiest orchids to grow in warm climates. They are best suited to indoor culture in a tweeked microclimate.

    Thanks everyone.

    I was going by the tag that came with the plant which stated it was a miltonia - but who trusts those generic tags anyway huh?

    It looks like I did the complete opposite of what I should have done for this plant. When I started seeing the rot spots, I thought that it disliked the airconditioned interior of the house and I moved it to the greenhouse to see if there would be any improvement.
    I guess that made the problems worse.

    Ok, so back indoors it will go.

    I am just not sure if there is still enough healthy tissue left for the plant to recover.

    Hehe yup. It does get pretty hot out here.
    July and August are usually the worst months with daytime highs reaching 110F.

    My average high temperature in the GH is around 87F, thanks to the misters, HAF and exhaust fan.
    So far, the highest temperature recorded inside the greenhouse is 95F which is still dangerously HOT.
