    Unhappy Phal orchids growing, but not flowering

    Hello there,

    I don't know what I'm doing wrong, my Phals are all growing, making new leaves and roots but not reflowering? Could light be an issue?

    Hello and welcome!

    How long of a time frame is all this in? Light definitely can be the issue. Also phals like a 20 degree F drop in temps from day time highs to nighttime lows to help initiate a spike.

    A year for some, but I've not seen A spike yet in any of those, so I may be a bit impatient there, 2-3 years for a few others.

    They look healthy, most are an emerald green, the ones which had pink flowers have some darker spots on them.

    Yesterday I attended the Ottawa Orchid Society May meeting where the guest speaker was from the Montreal Orchid Society, and is acknowledged as one of the top hybridizers/growers of phals in Canada. I photographed his slide show because I too have phals, and while I have gotten some of them to rebloom they didn't reblooom when I wanted them to (for the spring shows) and often the bloom scapes on them went off in six different directions....! I learned that the most critical elements are temperature and time under lights, month by month to bring them to bloom for, as an example the period from December through April when most folks would like them to bloom. And you cannot change the position of the plant in its tray ever, during the initiation stage, or the bloom scape will alter direction (as mine did).

    That's right. I photographed all of his slides that had value as a grower, my goal being to get reliable bloom when I want it. Apparently the initiation of the scapes requires two months, not more, and as noted temperature, and choice of that two month period required to initiate the development of a scape are the two most critical factors. The speaker is one of Canada's top orchid specialists, an AOS judge, and his hybridizing specialty is phals! If you need more info and it is on the slides let me know.

    i actually have watched videos on youtube on how to trick phals to bloom,..... but after making it blooms many times a year,.. the phal may skip blooming a year because it exhausting them..

    Thanks Lanny for the chart - it should be very helpful to Phal growers.
