    Question Buds Drying Up


    I have a Cochleanthes, and it is sending up many new buds. The trouble is, the first one dried up and fell off before it got a chance to open. It dried up right where the bud meets the stem, and nowhere else. Has anyone seen this type of thing before? I just got the plant a few months ago and it was in bloom when I bought it. It looks great, other than the dried up buds. It's making new roots, etc. Do you think the plant could just be stressed out by the move? Should I fertilize more? I haven't done a whole lot. I water with pure RO.

    That is a tough one, Katie. My first guess is stress, but since the plant if fairly new it could have a bug or something killing the buds. Any way to post a photo of the problem area? I am sure someone on here will be able to help you. Hang in there!

    Katie, one of the things that triggers blooming on a lot of orchid plants besides a temp and light level increase is a more abundant and steady supply of moisture. If a plant decides to put up a spike, it's because the conditions at the time are favorable for that. When buds are developing, it's really important to keep those conditions steady. Letting a plant dry off for too long between waterings, or exposing it to sudden temp changes during bud formation can all cause bud blast.

    As the season progresses and the sun changes its relative position, I've noticed here that, without even moving a plant, a plant's buds can blast if too much sunlight stays on them for too long and heats them up. The only reason I even found out is because I happened to be in the GH looking around during a time of day I'm normally doing something else. The late-morning sun had lowered enough in the sky at this time of year that it was coming in directly through the plate glass in the door, and hitting the inflorescence!

    So keep your watering steady without letting the roots of your plant go to dryness between waterings, and be sure the temperature on the buds remains relatively constant. Day-night variations as well should not be drastic.
