    Hi to this website!
    Looks great!
    i have a bulbo and I was wondering is it normal for the old growth to brown and dye off?

    Any growing hints?

    Steve, welcome!

    Old growths browning and dying off is perfectly normal. It's when new growths start doing that that you have to worry!

    Give those good light--Cattleya conditions--and let the roots dry off a little between waterings.

    If you have a digicamera, definitely post a pic when it blooms!

    Really? With a genera that big I know it is hard to make generalizations but I thought that bulbos like shady conditions. Please educate me. Thanks

    Cattleya conditions? I would definitely not do that.

    Lja must have misread the genus.

    Travis, it depends on the size of the Bulbo. If your 3rd PB out of three is browing off and dieing you do not have the corect conditions for them. Bulbos prefer to be mounted in a Phal light or just brighter condition with warm temps and very high humidity and copious amounts of water.

    They can be easily pot grown but need lots of water and therefore you need to watch the medium from breaking down too fast as they ca be susceptable to rot. this could be a reason why the old bulbs are turning brown.

    Some Bulbos may take Cattleya light but it is not recommended or required to get them to bloom and I would worry about burning them.

    my bulbos are not next to my catts, but i give them more light then phals.
    i would guess 2000 to 2500.
    but i give all my plants blistering light.
