Hello

Hi so I'm new to the art of Orchid growing. (And not having much luck) out of 2 orchids my moth orchid hasn't flowered since it got too cold a year ago and seems to be dying and growing...... the other is a brassia spp??? That seems to be growing leaves on a very thick stem.
could anyone advise me on what to do with either plant? I've tried reading up about it but get so confused with all the information out there.

Thanks Shona
