    Default Cymbidiums - Large but few flowers.

    I am not sure what is going on with my cymbidiums. For the past two seasons, the flower spikes have been producing extra large flowers but only have up to 5 flowers per spike, 8 if I am lucky.

    The large flowers are nice (2 to 3 times the normal size) but prefer that my cymbidiums produce sprays of 20+ flowers at normal size.

    I'm not sure if it is due to the summers being too hot (100F and higher) or if we are not getting enough cold nights in winter (35F-40F) to produce normal blooms.

    They never go inside the GH even in winter as they absolutely hate being inside the small cramped space.

    I bet it is the cool down that is the issue. At least you have big blooms.

    Cheers,

    I thought cymbid's needed a cool down to make flowers? Sigh...no wonder mine won't bloom!

    I've noticed that with any orchid. The fewer flowers produced the larger they are...not sure what causes this.

    Night temps? Do they need a bloom booster?

    Here's a current bloomer that is an example of this situation.
    This is a noid cymbidium. The flowers are normally half this size, but with much more flowers.
    The other interesting thing is that there were no bud blasts. All the buds produced bloomed. Its just that the plants produced relatively few buds in the first place.

    Maybe not enough "bloom" fertilizer? I just give them the normal dose of the "bloom" fertilizer from November through January. Then they get the same "balanced" mix just like the other orchids for the rest of the year.



    Nearly 6 inches across.


    Here are some other cymbidiums from previous seasons - although the issue is not quite as pronounced as the most recent one.




    This was by far the most extreme. 7 inch flowers with just two blooms.
    I dont think this one ever bloomed again.


    My "typical" growing climate:
    Winter: 60F days / 35F-40F nights outdoors. Bright sun at daytime - But can also have several days of continuous rain with 100% cloud cover.
    Spring: 80F days / 70F nights. Bright sun at daytime.
    Summer: 100F+ days / 80F nights. Burning hot sun at daytime.
    Fall: Wacky ~ thats all I can say.
