POTTING:

Use a potting medium that gives excellent drainage (orchid bark). For blooming size plants, medium size fir bark is right. To maintain good drainage, repot in fresh medium about every 2 years. If possible, repot in the spring months, and when in doubt about root health, repot. However, never over pot orchids!  

 
WATERING:
Water when the potting medium is nearly dry. Timing can be best determined by lifting the pot: nearly dry, it will seem quite light when water is needed. In general, these types of orchids will require water every 3-5 days in the spring/summer, and 5-7 days in fall/winter, depending on weather. When you water be generous, allowing water to flow freely through potting media. Water early morning, so leaves will dry by night to prevent disease.
 
FERTILIZING:
It is recommend the usage of Growmore fertilizer 20-10-20 (urea free) at half strength dilution at every watering, year-round. This type of fertilizer works well all year round.
 
LIGHT & LOCATION:
In the greenhouse, provide bright location and check leaf color as the plant grows: medium green indicates correct lighting. Yellow or burned foliage indicates too much light. Leaf temperature is a good indicator-if warm to the touch, reduce light. Minimum night temperature may go down to 55 degrees F. Daytime temperatures can go up to 90 degrees, as long as adequate humidity (40-50%) and good air movement is provided.
