    This morning I noticed both of my Meiracyllium trinasutum are losing leaves. The leaves look to be rotting at the base (turning black) and then all off. They are mounted on a piece of cork with no moss pad given bright light and warm/intermediate temps (right next to a few Cattleya walkeriana). I water them every other day in the winter and daily in the warmer summers.

    What could I be doing wrong?

    is it drying out good? I noticed that mine really does not like to sit wet during cool nights.

    have you checked for bugs?

    No bugs that I am aware of....

    I beleive it should be dry by nightfall as I spray first thing in the morning (most times before sunrise). Air movement is not the best where it is located, I wonder if that could be it?

    mine hangs on the roof of the gh. It gets very good air movement and grows quite well. I have had it a long time and did have it drop leaves once. In that situation it was because it was not drying out all the way.

    Thanks Forrest...I will keep my eye on it and make sure it is drying out as you suggest

    Even my plant lost its leaves,I've thinking to a radical rotting due to Pythium in Europe for this disease using the Propamocarb. The plant has lost even more leaves and I treated bacterial infection as the plant is healed.
    I don't know which products can be found in the United States.
    I also had experience of plants that lost their leaves due to the degradation of the cork. In this case to change the slab is a good solution even if it does not seem necessary.

    I think that Meiracyllium in general don't like cool damp conditions. Forrest's suggestion of putting it in a place with better air circulation seems like a winner. I'm experimenting with some now, and have had the same experience of leaves rotting at the base if they stay cool and damp for too long. In my care, this is one of the most finicky species.

    I vote for not drying out enough. I had a plant do this and it recovered after moving it closer to the fan.

    Yes it's right, but as well as provide better ventilation plant must be treated with a fungicide, this kind of rot is very fast and the plant may not survive

    I don't know how long these plants live. I had one for many years...it did very well and bloomed every summer. I basically ignored it. It was on a piece of cork...never got full sun...sprayed when I remembered to...almost never fertilized. Then this summer it just decided to die. Some orchids are just naturally shorter lived than others, although I don;t know if this applies to Meiracyllium................Take care, Eric

    I think I figured out what was happening. My warmer growers spend the winter in my bathroom. The humidity from the family taking showers is great for the plants but in this case when showering at night the humidity was condensing on the leaves!

    Thanks everyone for the tips as to what to look for, now I can only hope I can save them.
