    Default Psychopsis - how to initiate spike?

    Hello everyone!

    I purchased a Psychopsis mendenhall in November. It has 4 large pseudobulbs and 1 tiny pb each with a single leaf okay. One of these is really large and mature. The orchid shop I bought it from said that it is mature enough to start to initiate flower spikes. I just wondered if anyone has any ideas on how to help initiate a spike. I've got good temperature change 64F night to 74F day. I try to keep my humidity around/above 50%. I do have fertilizer (including bloom booster). Should I just wait and see or is there anything more I can do? Ideas much appreciated.

    Hope you mean 64f to 74f ,sounds like you are giving the plant a fighting chance to spike.
    They can be temperamental but if you have good light , water heavily then let them dry out , a little fert they should spike.

    From my observation this plant is very easy to produce spike at lowland with the temperature at night 24degree C and day time from 27 to 34degree C just give ample of lights wish it will reward you something.

    The flower of this plant could last for months and months.

    Good question - I bought one last fall too and it's a nice happy plant. Now I have some idea what it needs to bloom! Good luck, I hope to hear that you've had success.

    In my experience, psychopsis thrive if your nighttime temperatures are closer to you stated daytime temps, and get really warm in the daytime.

    There is nothing you're going to do to 'force" them to spike - when they are good and ready, they will, and after that, there's no stopping them (unless you let them get too cool).

    Maybe mine will like some time outside in the summer, it gets over 100 F here during the day! We keep the house fairly cool, my 89 yr old Mother in Law lives with us and likes a more even temperature. I don't know how that affects the plants, but she's doing great!

    Youve only had it since nov. 2013 presume? New Foliage doesnt develop until warmer temps. Spikes during cooler. I would guess you either bought it close to full (if not full bloomed) or cut spike? Either way it neeeds to go through stages before any new progress can be seen. Mimic environment for quick results, wetting drying fertilization, heat, cold, etc....

    Thanks everyone! I'll wait for warmer temps. The place where I bought it this last November (Kim-yep in 2013) had another that did have a spike and so I know it's possible for them to make a spike where I live, I'm just kindof learning as I go on this one. I guess I'm a little eager to see it spike 'cause as I understand it it can produce flower after flower on the same spike for year after year!
