    Default MORE ROOTS but no Orchid Flower Spike

    need some help with my Phalaenopsis.
    fertilized my orchids with 15-30-15 every other weekend. i bought my phalaenopsis last yr before winter and hoping they will rebloom by spring. 5 of the phalaenopsis rebloomed last early spring except this one.
    every time i notice some "swelling" on the side of this orchid, i am crossing my fingers and hoping it is a flower spike BUT... again, another healthy root...
    i stopped fertilizing this one... but i am still hoping it will produce her flower spike for me...
    any advice out there???

    Your plant looks super strong and healthy!
    It is not strange that a Phalaenopsis does not rebloom the first year as it need to adopt to your environment. It has been stressed at the nursery to put out a massive bloom under perfect conditions and need to recover and adopt.
    Phalaenopsis hybrides also often need a cooler period to set a spike and this naturally happens sometimes during the autumn and therefore they flower in winter to early spring. In Sweden, we get lower temperaturs already in August-September and therefore Phalaenopsis usually rebloom at christmas.

    Just be patient and you will get flowers.

    did you signal the Phal and exposed it to a temperature drop of at least 10 degrees celcius diurnal from day to night?

    I was headed in that direction, too.

    However, Dr. Yin-Tung Wang (then of Texas A&M) showed that it is a 10°-15°F drop in the average growing temperature for a couple of weeks that induces flower spikes in phals, not the day-night difference.

    Ray, that is exactly what usually happens in the autumn up here in th enorth. The temperature on a windowsill is usually lower than the bulk room temperature when the temperature outside drops.

    You can acctually predict the state of peoples windows and homes by getting information on when (or if) their phals flower! Modern eco house usually create problems as the temperature is stable over the year, resulting in phalaenopsis have problems to flower. But in older houses the draft from badly isolated windows lower the temperature earlier when the outside temperature drops and phalaenopsis plants flower earlier...

    I actually had an opportunity to test Dr. Wang's conclusion last year.

    I plotted the daily highs and lows for 2011, then averaged them. To a plot of the data, I added a 14-day moving average.

    Our highest average was about the first of August, and it had decreased to about 15°F below that about October 10. If the theory was to hold true, I should have expected to see spike initiation some 6- to 8 weeks later - mid- to late November - and that is exactly what happened.
