LIGHTING
Sufficient lighting is a must for successful cultivation. Phalaenopsis prefer either an east or a lightly shaded south facing window. West-facing windows should be used with caution. Depending upon the location of the home, the west-facing window may become very hot during the late spring through early fall causing the foliage on your Phalaenopsis to burn.
TEMPERATURE
Phalaenopsis thrive under normal household temperatures. For the best results, provide nighttime temperatures between 60 to 65°F and daytime temperatures between 75 to 85°F.
WATERING
Depending upon the temperature, Phalaenopsis potted in bark should be watered about once or twice a week. During the summer, the plants may need to be watered every 4-5 days. The following rule of thumb for watering should be as followed: more heat, more water and less heat, less water. Phalaenopsis potted in Chille sphagnum moss should be watered less often, about every 7 to 10 days. Phalaenopsis prefer to be kept on the moist side, however, this does not mean that they like to be left in standing water. Try to water the plants early in the day so that the foliage will be dry by nightfall.
HUMIDITY
Phalaenopsis prefer 50% humidity. Often a kitchen or bathroom will provide sufficient humidity. Humidity Trays may be needed for other locations in the house.
FERTILIZER
Phalaenopsis must be fertilized on a regular basis! For best results, use Orchid Nutrients every other week. It is recommended to pre-water the plants before applying the diluted nutrient solution if the potting media is dry.
POTTING
Phalaenopsis may be grown in either Chille Sphagnum Moss or Medium Orchid Bark Mix. Phalaenopsis should be repotted once every two years. Ideally Phalaenopsis should be repotted immediately after flowering.
