    Default Lycaste Disease/Flower

    My Lycaste Takagamine (Chita Melody ‘Star Fire’ x Sunrise ‘Ena’) flowered recently. I had it growing in an east window and the leaves got sunburned. I wonder if that is the damage noted on the petals/sepals of the flower or is this damage petal blight? Also, there were 3 pb's when I "rescued" this plant from a local vendor. All had some degree of brown discoloration and shriveled. Isn't this normal aging or is this a fungal infestation?

    I'm not a Lycaste expert. I think you're lycaste is very pretty. I don't think it has a serious illness.
    The bloom looks like water droplets didn't dry and parts of the bloom had a rot.
    The peusdobulb has a rot. I'm not sure the cause, but I think it is water related. I would remove it with sterile tools. I don't think it is very serious.
    Perhaps use a fungicide or dab cinnamon on the wound. cinnamon is a natural fugicide.

    My Lycaste aromatica has its very oldest psuedobulbs turning brown. I know that mine is from another section and it is deciduous. It rotted because it was watered too early when it broke dormancy.

    Julie seems to know more about Lycastes....

    Welcome to the forum BikerDoc.

    I ahve no clue about Lycastes, but thought I would just say hello. I am sure there will be others who post soon who will be able to offer you more advice.

    Hi Biker,

    The deciduous p-bulbs on Lycastes will shrivel and brown as the plant pushes up new growth. It appears very similar to a fungus, and it can freak you out quite a bit. I was sure mine had a fungus when the same thing started last fall. But I watched it like a hawk. The p-bulb felt a bit mushy for a while, but it didn't spread. I had some browning on a second p-bulb, but it never progressed. The oldest one sort of consumed itself from within and eventually dried out until there wasn't much more left of it than an empty husk (and then I cut it off.)

    I'd say if it's not a fast-progressing mushy problem that spreads to other p-bulbs, then it's just natural senescence of the plant (aging.)

    The flower looks like a culture problem and not a fungus. If you had a sunburn problem with the leaves, and if when you water, the flowers get wet, I'd suggest that water droplets on the flowers magnified the sun and burned the crap out of those water droplet spots. That's what it looks like.

    By the way, welcome to the forum!

    Julie

    Thanks, I suspected this is normal aging of older pb's. The shriviled bulb is otherwise very firm and some is still green, so I doubt any serious problem. The petals may be damaged from water as some of you have suggested. Hope it produces more pb(s)!!!!

    This is the time of year for new growth - do you see any springing forth? They don't look like p-bulbs at first, but they'll eventually mature into it.

    They're a great genus! Hope your plant does well - keep us posted!

    Mine has a new growth started, while the old bulb is sending a bud. This is the time for new growth.
    So the brown pseudobulbs on mine were not from watering too early then....

    Is yours deciduous too?

    It is, in stages. It loses the outer leaves in the fall, and the huge leaves (my big one has huge leaves), have yet to drop, but I'm sure they will in the course of the upcoming season. I got the big guy about July-Aug last year, so I don't have a full season of experience yet. My powelii is about that old, but was a weary immigrant from Central America. It's got great new growth coming up, but much more normally sized for a Lycaste. It is deciduous.

    So is this typically what we can expect from deciduous p-bulbs? That they will sorta brown and eventually dry up? What other types of common orchids are deciduous?

    Not all Lycastes are fully deciduous, some are only semi. Some Dends are fully. Some Phal species are in the wild, but tend not to be in cultivation. Many odd-ball genera are.

    It helps to know if yours is. It saves on the heart attacks when the leaves brown and fall off!
