Dendrobium unicum buds dying

[moniluhum]

This plant was doing well. The buds came out looking healthy. Now the buds are shriveling and turning brown. WhenI saw the change in the buds, I lowered the amount of light. It doesn't seem yo help. Can anyone help?

Sorry to hear about the bud blast. possible reasons

1) any sudden change in temperature?. did you move this from any other location to a higher or lower temprature?
2) any chemicals/gases (ethylene?) source near by?.
3) AC duct or heater vent near by?

hope rest of the buds bloom.

You can't rule out a possible infestation. Thrips can also cause premature blasting and this is the season for them in our region. Open the blasted buds to look for teeny black insects and/or yellow larvae.

? hows the search going?

[moniluhum]

I do not see signs of infestation. Some of the flowers have opened. I discoloration maybe due to the color of the flower. I say maybe because the flowers appear to be withered and unhealthy. The a/c had been turned on a few days before the orchid buds began to open. Not sure what caused the withering situation. The plant would have been a great show because there are so many buds. Anyone have ideas on the withering? I did not water everyday because i thought dendrobiums do not need water daily until AFTER they bloom. Please give me your thoughts.

What was the temp in your home before the a/c?

[moniluhum]

It appears the bud change is normal as the plant has now flowered. Im not sure the flowers are healthy, but here it is.

Looks good! I'd take a pic of mine, but it's about as dead as dead can be! Does yours have any fragrance? I've read that they should, but I never detected any on mine.
