Cymbidium bulb rot and yellowing leaves in Semi-Hydro.

[Cym Ladye]

I suspect your plant has developed crown rot. Smell the bulbs. You will detect an abnormal, rotting smell. It is very difficult to stop crown rot, but if you cut the connection starting with the worst bulb and continuing until you see a clean cut to the next bulb, you may be able to save the remaining plant. I know of nothing, at least nothing I have tried, which will stop this.
