Quit watering it so much. Orchids bloom in the natural environment during the dry season . That is when their pollinators are out. It is usually dry then so I would curtail watering and keep it from cool draghts or close to cold windows.
That's so interesting because now that you mention it, I had sort of ignored the plants for a little while with the holidays and all and thought I needed to get back on watering. I assumed it turned brown because of lack of water and never thought of the opposite. Thanks!
