Dendrobium is a genus of orchids that consists of more than 1,000 different species. They are native to Asia and Australia and typically grow high in the boughs of trees. Due to their native habitat, it can be difficult to provide the proper environment for growth. Dendrobium orchids are commonly grown in containers indoors, as they can tolerate only a very narrow range of temperatures.
Fill a small planter, between 6 and 10 inches in diameter, with fern fiber. Place the orchid into the planter, mixing the roots with the fern fiber. Let longer roots hang over the side of the container.
Keep the dendrobium orchid at a constant temperature between 55 and 80 degrees Fahrenheit. Outdoor orchids must be transferred indoors anytime the temperature leaves this range, or they can sustain damage or die.
Ensure the humidity is at least 40 to 50 percent at all times. Use a spray bottle to mist outdoor plants three to four times a day during periods of low humidity. Place a humidifier near orchids grown indoors to keep the humidity level consistent.
Place the orchid in a location that receives bright sunlight for most of the day. Place a thermometer near the orchid to ensure the temperature stays in the recommended range. Move the plant to a shady location if the temperature becomes too hot, or if the leaves begin to wilt.
Water dendrobium orchids once every two to three days during spring and summer. Soak the growing medium and any roots having over the side to ensure that plenty of moisture is absorbed. Reduce watering to once weekly in winter.
Feed the orchids every other week in spring and summer using a balanced 10-10-10 NPK fertilizer. Cease fertilizing in the fall and do not resume until early spring.
