Plant your dendrobium orchid in a pot filled with a potting medium of ten parts of fine grade fir bark and one part of orchid mix purchased at any home and garden store.
Place your dendrobium orchid in a pot located in a bright spot in your home. Do not place them outside in direct sunlight. If the orchid is on a window sill, use a sheer curtain to block out the harmful sun's rays.
Keep the nighttime temperature between 60 to 65 degrees F. The daytime temperature is ideal at 75 to 85 degrees F. Let the potting soil dry out between watering.
Add fertilizer to the soil of your dendrobium orchid once a month. Purchase a fertilizer formulated for orchids and follow the label instructions. Do not over feed the orchids or you might burn the roots and hinder blooms.
Encourage air movement around your dendrobium orchid to prevent mold from developing on the joints of the leafs. Open a window or set up a small fan--facing away from the plant. (Soap and water cleans mold off the flowers well.)
