Cymbidium bulb rot and yellowing leaves in Semi-Hydro.

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.

Hello Cym Ladye, I have smelled the bulbs and there's no 'abnormal, rotting smell'! and the smell is the same smell of all the bulbs in the 3 other pots. However before you answered I got some Hydrogen Peroxide 30%, and used it at 5% per liter of water and flushed the pot.

In your vast experience, what is the reason for crown rot?

I guess I just have to wait and see, and will keep updating this thread.

Thank you for your time.
