Care tips for your Phalaenopsis Orchid from Bell Flowers:

The orchids prefer temperatures between 60-85 degrees Fahrenheit - locate away from drafts.
Watering: The ice cube trick; Place three regular size ice cubes on the moss surrounding the bottom of the plant once every seven days.
If you don't have access to ice, pour a small amount of water onto the moss surrounding the base of the plant once a week. The soil should dry out between waterings and never let the plant stand in water. 
Lighting: Place in a bright, well-lit location and avoid direct sunlight. Once the orchid has gotten used to its new home it will begin to flourish!
