    Does anybody grow these species? I got a very weak import from Asia several months ago and they are just dropping leaves. I don't think it is a fungal infection, I believe my culture is just not right.
    Any input is much appreciated!

    I find many imported Bulbophyllum sulk for a few months, dropping leaves, etc. and then generally recover provided the right conditions. I have started taking nearly all of the freshly imported Bulbophyllum miniatures and putting them in a net pot with NZ sphagnum. Once they start growing, I typically mount them. As for B. triastriatum, I have had that for a year and it did drop leaves at first, but has since put on new growth and has bloomed twice. I grow it on the cool side and moist, with about half as much light as the PNG Dendrobium that grow above it. Would love to have a lambii.

    Thank you, Chuck.
    I think I've been keeping them too dry. They are mounted and drying out between waterings just a bit. Should be fine for mature established plants, but freshly imported ones probably need more nurturing.
