Phalaenopsis (fal-en-OPP-sis) The "Moth Orchid" the easiest and most rewarding orchids to grow. The plants adapt well to the environment of the home or office.  The flowers will last for 2 to 3 months. LIGHT - the Phalaenopsis likes bright light, a window that faces east is ideal.  A covered patio where it is protected from the mid day sun is perfect.  The leaves if exposed to direct light will develop sun spots. TEMPERATURE – Phalaenopsis should be above 60 °F at night and between 70° and 82 °F during the day. Although higher temperatures result in fast leaf and root growth, lower light and good air movement must accompany. Do not exceed the limit of 95°F. Temperatures below 78 °F for three to five weeks with good light are needed for initiating flower spikes. Wide fluctuating temperatures and low humidity can cause bud drop on plants with flower buds ready to open. WATERING – is especially critical for this orchid. The medium should never be allowed to dry out completely. Plants should be thoroughly watered and not watered again until nearly dry, but not until bone dry. In the heat of the summer in a dry climate, this may be every two to three days, whereas during the winter of a northern climate, it may be every ten or more days. Do not allow water to accumulate in the crown for long to avoid contract decaying diseases. Do not sit pots in standing water for long. POTTING – is best done in late spring or early summer after blooming has completed. Phalaenopsis plants must be potted in quick draining mixes, such as fir bark, tree fern fiber, chunky sphagnum peat, charcoal, perlite, or combinations of these. Root rot will occur if plants are allowed to sit in an old, soggy medium. Your young plants should grow fast enough to need repotting yearly and should be potted in a finer grade medium to allow good root contact. Mature plants are potted in a coarser medium may stay in the same pots for years, provided that medium is changed when needed. To repot, remove all old medium from the roots, trim off rotted roots, and spread the remaining roots over a handful of medium in a pot. Fill the rest of the pot with medium, working through the roots, so that the junction of the upper roots and the stem is slightly below the medium. Be careful not to leave large air pockets in pots. Use a stick to push the medium in between the roots. Keep plants in shade and wait for one to three days before watering. Fertilizer – Should be applied every 3rd watering. http://www.orchidmerchant.com ...read more
