    Default Phal buds failing - not a disease

    This has gone on with Phals as long as I've been keeping them. Actually all orchids for that matter, so it may be normal - but it's still frustrating and I'd like to try to have more blooms and less failed buds!

    The current sad plant is a Phal Joy Fairy Tale 'Joy' (someone recently posted a photo of this flower on this site).

    I have two spikes and one flower. One bud has aborted (turns yellow and fades), and a second one on a different spike is about to do the same. I have one more bud to hope for - otherwise it looks like this extraordinarily promising flowering season for this plant is pretty much a bust.

    Reasons under consideration (by me, pending your input!)

    - inadequate humidity. This plant and my phals are on humidity trays or trays of gravel and water, and surrounded by many other plants. But, I occasionally don't maintain the water in the gravel enough, and this isn't vietnam or the phillipines

    - too much blooming. This doesn't apply to all my phals (some won't bloom for me, or are too young/small or something), but this one bloomed in august, and gets a lot of light for a phal. As a result, the leaves are successively getting smaller. I'm considering moving the over-blooming phals to a darker location and just let them grow for a while. BUT - I don't know if this is a cause of bud drop.

    - I know this isn't a disease. It happens to all my phals, they are fine, this plant shows no signs of problems. I've had sick Phals and sick orchids, this isn't one, and this problem isn't associated with disease.

    Awaiting your expertise.....

    Tell us about your temperature ranges that the orchid experiences. Day and night.

    Thanks

    Do you fertilize? Phals are heavy feeders which can be related to the medium they grow in and the amount of light they get. My humidity is low but mine bloom well.

    Could it be pests?

    It's not pests. I fertilize half strength weekly in spring summer and fall, and quarter strength less often in winter; in winter every other watering is water (not feeding). (So they're not fed much in winter). The temp range is 65-75 in the house, but these spend some time in the windowsill where it is much warmer in Aug-Sep on hot days; and prob much colder in winter. However, this plant is away from the window currently, in a lower light situation, since I am concerned about the leaves getting progressively smaller.

    I know Phals need a temperature drop for spike initiation. What does day-night temp have to do with maintaining the bloom?

    Will take pics and post, later. Thanks

    I know that my Phal. buds had not progressed at all over the past month. They were in an area that is in the 60-62 range at night and 66-68 during the day. They are in the basement under lights so day night are reversed. I brought them upstairs yesterday so that they will have 65 nights and 70-72 days. Hoping that kicks them back into gear. I'm sure you know what you are looking at regarding bugs but the symptoms you're describing sound exactly like small mealybugs inside the flower buds.

    You can see that the newest leaf is smaller than the rest. That small bud looks blasted to me; I'm hopeful the smallest one isn't finished, too, but I fear it might be.

    I watered this morning, thinking maybe it's dry, but it wasn't very dry.

    But it would be odd to have mealybugs inside the flower, and not on any leaves; nor on any plants nearby including the ones it is touching; and on the succeeding buds but not the first one, without traversing the leaves or stem to get to those younger buds - wouldn't it? I have had mealy bugs this winter, but I haven't seen any lately.

    Karin suggested feeding. Are you and if so, how often, how much etc.

    He says half strength and quarter strength, but of what? The media looks kind of broken down. Maybe they need a repot. If you used clear pots you could see the roots. My guess is rotten roots.
