Hi everyone who is part of this forum. Im hoping you can help me out, I recently brought Brassia 'Santa Barbara' from the RHS Orchid Show in london.

It is a small plant with 3 pseudobulbs. One of the bulbs is looking very unhappy. It has started to go black at the bottom where it is touching the bark it is potted up in. The leaf from the pseudobulb is also pale and yellow.

I mist my orchid 2/3 times a week but have not watered it since i have had it.

Any advice would be much apreciated

Thanks Nic
