Phalaenopsis, (fail-eh-NOP-sis) the moth Orchid, is perhaps the best Orchid for growing in the home, and is also a favorite with greenhouse growers. Well-grown plants can flower often, sometimes with a few flowers throughout the year, though the main season is late winter into spring. Average home temperatures and conditions are usually sufficient. Flower stems on certain hybrids can be forced to rebloom by cutting the tip off after the initial flowering. Only healthy plants should be induced to flower repeatedly. Culture for Doritis, a related genus, thought by some to be conspecific with Phalaenopsis, and Doritaenopsis, a hybrid between the two genera, is the same as for pure Phalaenopsis.

Light. It is easy to provide for Phalaenopsis. They grow easily in a bright window, with little or no sun. An east window is ideal in the home; shaded south or west windows are acceptable. In overcast, northern winter climates, a full southern exposure may be needed. Artificial lighting can easily be provided. Four fluorescent tubes in one fixture supplemented by incandescent bulbs are placed 6 to 12 inches above the leaves, 12 to 16 hours a day, following natural day length. In a greenhouse, shade must be given; 70 to 85 percent shade, or between 1,000 to 1,500 foot-candles, is recommended. No shadow should be seen if you hold your hand one foot above a plant's leaves.

Temperature for Phalaenopsis should usually be above 60 F at night, and range between 75 and 85 F or more during the day. Although higher temperatures force faster vegetative growth, higher humidity and air movement must accompany higher temperatures, the recommended maximum being 90 to 95 F. Night temperatures to 55 F are desirable for several weeks in the autumn to initiate flower spikes. Fluctuating temperatures can cause bud drop on plants with buds ready to open.

Water is especially critical for Phalaenopsis. Because they have no major water-storage organs other than their leaves, they must never completely dry out. Plants should be thoroughly watered and not watered again until nearly dry. In the heat of summer in a dry climate, this may be every other day; in the winter in a cool northern greenhouse, it may be every 10 days. Water only in the morning, so that leaves dry by nightfall, to prevent rot.

Humidity is important to Phalaenopsis, the recommended humidity being between 50 to 80 percent. In humid climates, as in greenhouses, it is imperative that the humid air is moving. Leaves should be dry as soon as possible, always by nightfall. In the home, set the plants on trays of gravel, partially filled with water, so that the pots never sit in water.

FERTILIZING YOUR ORCHIDS: Our nursery mixes its' own fertilizers. You will not find these products anywhere else. We use two different mixes, 'Green and Grow' and 'Bloom and Root'

FERTILIZER:Fertilize every week. Use 'Green and Grow' for two weeks and then 'Bloom and Root' for one week. Remember to water before fertilizing


Potting is best done in the spring, immediately after flowering. Phalaenopsis plants must be potted in porous mix. Potting is usually done every one to three years. Mature plants can grow in the same container until the potting medium starts to decompose, usually in two years. Root rot occurs if the plants are left in a soggy medium. Seedlings usually grow fast enough to need repotting yearly, and be repotted in fine-grade medium. Mature plants are potted in a medium-grade mix. To repot, remove all the old medium from the roots, trim soft, rotted roots, and spread the remaining roots over a handful of medium in the bottom of a new pot. Fill the rest of the pot with medium, working it among the roots, so that junction of roots and stem is at the top of the medium.
