Dendrobiums are one of the largest families of orchids with somewhere around 1000 species being known. There are some Dendrobiums that are very large, as well as some miniatures. Some come from warm sea-level conditions of the equatorial Pacific islands, while others originate in the near alpine climate of the Himalayan foothills. Dendrobiums are found in areas of the Eastern Hemisphere, including Australia, throughout the South Pacific and
Philippines, Southeast Asia, India, and a small representation in Japan. Although the color range is varied, most hybrids offered for sale are usually
lavender, white, golden-yellow, or combinations of these colors. Some of the more unusual species and hybrids can be bluish, ivory colored, brilliant
orange or scarlet, or have exotic markings. Most of the evergreen Dendrobiums are not fragrant, however the deciduous species can have a fresh citrus scent or smell of raspberries.
Dendrobiums prefer bright, filtered light. Dendrobiums do well placed near a window that provides early morning or late afternoon sun. Take caution with direct light, as your plant might burn.
Dendrobiums thrive as household plants and prefer temperatures between 55F and 80F, and should not be exposed to extreme cold.
Allow the potting media to completely dry out before watering. Keep in mind that Dendrobiums should be properly drained. Water about twice per week or as needed.
Dendrobiums must be fertilized on a regular basis. For best results, use Better-Gro® Orchid Plus® Fertilizer every week, and Better-Gro® Better-Bloom Fertilizer at every fourth watering to promote large, abundant blooms.
Dendrobium prefer to be grown in Better-Gro® Dendrobium Mix or Better-Gro® Special Orchid Mix®. Dendrobium should be repotted once every year and ideally they should be repotted immediately after blooming.
Common pests associated with Dendrobiums are scale, mealy bugs, and spider mites. These can be treated with pesticide sprays such as Orthene®, Sevin®, Malathion®, or Neem Oil®. Spider mites can be treated by either washing the upper and lower sides of the plant leaves with soap and warm water, or with the use of insecticidal soaps or pesticides.
