Phalaenopsis
Fayl-eh-NOP-siss
Phalaenopsis, the moth plant , is probably the simplest orchid for growing within the home, and is additionally a favourite with greenhouse growers. Well-grown plants can flower often, sometimes with a couple of flowers throughout the year, though the most season is late winter into spring. Average home temperatures and conditions are usually sufficient. Flower stems on certain hybrids are often forced to rebloom by cutting the tip after the initial flowering. thought by some to be conspecific with Phalaenopsis, and Doritaenopsis, a hybrid between the 2 genera, is that the same as for pure Phalaenopsis.
Light is straightforward to supply for phalaenopsis. They grow easily during a bright window, with little or no sun. An east window is right within the home; shaded south or west windows are acceptable. In overcast, northern winter climates, a full south exposure could also 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 each day , following natural day length. during a greenhouse, shade must be given; 70 to 85 percent shade, or between 1,000 and 1,500 foot-candles, is suggested . No shadow should be seen if you hold your hand one foot above a plant's leaves.
Temperatures for phalaenopsis should usually be above 60 F in the dark , 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 within the autumn to initiate flower spikes. Fluctuating temperatures can cause bud drop on plants with buds able to open.
Water is particularly critical for phalaenopsis. Because they need no major water-storage organs aside from their leaves, they need to never completely dry out. Plants should be thoroughly watered and not watered again until nearly dry. within the heat of summer during a dry climate, this might be every other day; within the winter during a cool northern greenhouse, it's going to be every 10 days. Water only within the morning, in order that the leaves dry by nightfall, to stop rot.
Humidity is vital to phalaenopsis, the recommended humidity being between 50 and 80 percent. In humid climates, as in greenhouses, it's imperative that the humid air is moving. Leaves should be dry as soon as possible, always by nightfall. within the home, set the plants on trays of gravel, partially crammed with water, in order that the pots never sit in water.
Fertilize on a daily schedule, especially if the weather is warm, when the plants are most frequently growing. Twice-a-month applications of high-nitrogen fertilizer (such as 30-10-10) are appropriate where bark-based media are used. Otherwise, a balanced fertilizer is best. When flowering is desired, a high-phosphorus fertilizer (such as 10-30-20) are often applied to market blooming. Some growers apply fertilizer at one-quarter strength with every watering; this is often best for warm, humid conditions. When cooler, or under overcast conditions, fertilizer should be applied twice per month at weak strength.
Potting is best wiped out the spring, immediately after flowering. Phalaenopsis plants must be potted during a porous mix. Potting is typically done all to 3 years. Mature plants can grow within the same container until the potting medium starts to decompose, usually in two years. plant disease occurs if plants are left during a soggy medium. Seedlings usually grow fast enough to wish repotting yearly, and will be repotted during a fine-grade medium. Mature plants are potted during 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 couple of medium within the bottom of a replacement pot. Fill the remainder with the pots with medium, working it among the roots, in order that the junction of the roots, and therefore the stem is at the highest of the medium.
In nature, phalaenopsis orchids usually blossom once a year. New Flower spikes typically appear in late fall and lengthen during the wintertime, producing blooms in late winter or early spring that last for months on end.
