Phalaenopsis are among the easiest and most rewarding orchids to grow. An American Orchid Society demographic survey showed that Phalaenopsis have become America~s favorite orchid. The plants adapt well to the environment of the home or office. From the time that the first flower bud opens, the sprays will remain in bloom for the next 2 to 3 months.
Lighting
Sufficient lighting is a must for successful cultivation. Phalaenopsis prefer either an east or a lightly shaded south facing window. West windows should be used with caution. Depending upon the location of the home, the west window may become very hot during the late spring through early fall. The foliage on your Phalaenopsis may 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 rule of thumb for watering should be as followed: More heat more water, less heat less water.
Phalaenopsis potted in New Zealand sphagnum moss should be watered less often, about every 7 to 10 days.
Phalaenopsis prefer to be kept on the moist side. This does not mean that they like to be left in standing water,however try to water the plants early in the day so that the foliage will be dry by nightfall. To prevent bacterial and fungal disease use Physan 20 once a month.
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 Norman's Optimal 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 New Zealand Sphagnum Moss or Medium Orchid Bark Mix. Phalaenopsis should be repotted once every two years. Ideally Phalaenopsis should be repotted immediately after flowering.
Pests
Common pests associated with Phalaenopsis are scales, mealy bugs and spider mites. X-CLUDE, an encapsulated pyrethrum time-release insecticide is the most efficient method of pest control.
Flowering
Phalaenopsis plants may flower again for a second time. After the plant goes out of bloom, cut the stem just under the the first flower on the spray. A new spray of flowers may emerge from the node below.
