The genus Dendrobium contains around 1000 species. Most of them are epiphytes (tree dwellers) and are found in tropical and sub-tropical regions. Flower types vary from being enormously-upright to trailing, clustered or singles and many are sold unnamed. They are easy to grow. Most Dendrobium flower from late winter through early summer on stems which average 60 cm (2feet) long.
Keep Orchid Dendrobium Oshin plants in bright but indirect light. Additional shade may be required in summer. Aim to keep Dendrobium moist throughout the growing season. Mist the plants in the early morning and late evening.
Dendrobium in the picture above and below is called Dendrobium Oshin.
The plants requires a high degree of humidity during the growing period. In Spring and Summer feed Dendrobium monthly with a high Nitrogen food. This will help in robust growth of the plant. Repot every few years in spring.
Some dendrobiums produce plantlets from their stem points; these grow aerial roots. Once the roots have reached 2.5 (1”) long, gently twist the plantlets free and pot up. Water well, cover with a plastic bag and keep in warm semi-shade for the plants to become established.
