Phalaenopsis
(fal-en-OPP-sis)
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.
