Caring for your Phalaenopsis OrchidTemperatureA minimum night temperature of 62° to 65° is optimum, but temperatures as low as 50° will not harm the plant. Contrary to the orthadox Phalaenopsis culture, lowering the night temperature 3-5° seems to initiate flower spikes. Day temperature should range between 75° to 85°, although temperatures as high as 100° for short periods will not harm the plant if good air movement and humidity are maintained. LightGood light promotes good flowering. Do not place these orchids in full sun all day, but give them as much light as they can take without burning. A bright windowsill is ideal. WaterAlways water orchids before noon so that the plants are dry before night. How often to water depends on the planting medium used, the type of pot (plastic or clay), and the size of the pot. Strive for a damp medium, not soaking wet, and never allow the plant to become bone dry. When you water, water well, and then let the plant become almost dry before watering it again. FertilizerFor Phalaenopsis in bark or bark mixes, feed a complete 30-10-10 with every other watering after the last flower has wilted. RepottingPhalaenopsis should be repotted at least every two years. This is best accomplished when the plants are in active growth so that they become reestablished more readily. The choice of potting medium is up to the individual, although fir bark an bark mixes are by far the most popular and easiest to use. When repotting, all dead and decaying roots should be removed. After repotting, withhold water for a day or two to allow the injured roots to heal. |
