The dendrobium genus of orchids has more than 100 species in a wide range of shapes and sizes. They are called "Phalaenopsis type" orchids because their flowers look like the flowers of the Phalaenopsis genus. Dendrobiums shed their leaves during in the fall and winter. Dendrobium orchids are often used as cut flowers. Their cane-like stems and vibrant color create striking arrangements. Dedrobiums do require special care in order to flourish.
Dedrubium orchids like daytime temperatures of 75-85 °F. At night, it prefers cooler temperaures of 60-65 °F. The plant can tolerate extremes if they are not long or frequent. Prolonged exposure to extreme heat or cold causes wilting and eventual death.
Dendrobium orchids like full lighting in the mornings, but need to be in the shade between 11 a.m. and 3 p.m. Use an overhead source of light (lamp or potlight) for best results. If you work during the day, however, place the plant in a east-facing window so that it can receive the light it needs.
Let the potting medium dry out completely between waterings. In nature, orchids have evolved to surviving periods of extreme dryness between rains. If they are kept moist, their roots develop root rot, and the plant becomes stressed.
Feed dendrobium orchids with fertilizer formulated for orchids. If you can't find an orchid-specific fertilizer, use a high-nitrogen fertilizers (25-9-9). Fertilize monthly with a dilution of one teaspoon per gallon of room-temperature water.
Dendrobium orchids grow more slowly than most flowering plants. They need to be repotted only once every two years. Transplant the orchid into a new pot after it blooms or starts new growth.
