Phalaenopsis
(The Moth Orchid)
The Phalaenopsis genus is in the tribe of Aerides. A close relative of the Doritis and is in the same
tribe as the Vanda Orchid. Phalaenopsis is Greek for Phalluna meaning Moth and opsis meaning
resembling. Thus the name Moth Orchid. Their growth habit is monopodial, meaning that the leaves
are produced from only one point, commonly known as the crown.
Phalaenopsis do not have a water storage mechanism, like a Pseudo bulb, but they
can store water in their thick fleshly leaves. The flower stalks can produce over 12
flowers per stem. Colors range from artshades, pinks, stripes, spots, yellows, and of
course white, which is the most popular color.
How to keep your Phalaenopsis healthy
Light: Moderate to bright indirect light. Ideally, early morning, direct light as in an east window. West
windows are good provided direct sun is not on the orchid during the heat of the day. Evening sun is
OK. A south window with defused light or away from the direct sunlight. The foliage should be
medium green color, indicating the orchid is getting enough light to flower.
Temperature: The ideal temperature during the day is 75 to 85°F. Higher temperatures to 98°F will
require less light and more air movement to prevent sunburn on the leaves. Night temperatures can
range from 58-64°F at night.
Watering: Watering should be done in the morning hours. You can water heavy overhead, or soak
potted orchid in the sink for ten minutes. In cold areas the water temperature should not be below
45°F. Watering with ice cubes in NOT recommended. Water is an essential nutrient for plant
development. In moderate light water once every 5 to 7 days in winter, and every 3 to 4 days in
summer. This may need to be increased in bright light conditions. When in doubt, check the bottom
of the pot, if it looks dry, then water.
Feeding: Phalaenopsis are heavy feeders and require fertilizing every second watering. Use
Gublers Pro Blend Orchid Food 19-8-16. This formula is exactly what we use to grow our
Phalaenopsis year round. By feeding every second watering, you will be feeding more during the
longer days of summer when the orchid requires more water, and feeding less in the shorter days of
winter.
Repotting: Should be done once a year. It is best to repot in the spring after flowering. Plants that
have overgrown their container should be potted into a suitable container the next size larger. You
may choose any container, provided it has good bottom drainage. We do not recommend pots with
slits on the side. Transplant using Gublers Orchid Grow Mix- Fine Grade for all Phalaenopsis
orchids.
What to expect: Phalaenopsis mainly bloom in the spring season. They flowers can last Through
cultural techniques, we are able to trick the Phalaenopsis into blooming virtually any time of the
year. The most flowers produced on the stem is in the spring season. After flowering you should cut
the flower stem one inch above the second node closest to the base of the plant. This gives you the
possibility to have a secondary flower stalk within eight weeks. Moth Orchids produce two new
leaves a year. They are a good beginner orchid, and make a wonderful addition to any orchid
collection.
