Dendrobium Orchids

Dendrobium orchids are a massive genus of orchid plants. It contains over a thousand different species of orchids and hybrids. These orchids originally found their homes in Southeast Asia, including Japan, India, the Philippines, Vietnam and even Australia. Because these plants are highly adaptive, they can thrive in both high and low altitudes and in various climates.


Watering through the summer months should be more frequent, then less frequent in the colder months. In general, you should water your orchid in the morning using tepid water. While the plant is actively growing, the soil should be moist, and when the plant is inactive, or not growing, leave it dry. Dendrobium orchids go through many stages of growing, blooming, and hibernation. Be aware of these and adjust your care accordingly.


Medium light is ideal. Direct sunlight is likely too harsh for an orchid. Keeping your orchid at an eastern-facing window is the best place for it, but a shaded southern window area will also work. While some orchid species are partial shade Dendrobium orchids, while others are full shade Dendrobium orchids. When considering shade, remember the orchid species.

Temperature and Humidity

Temperature during the day should reach no higher than 29.4 degrees Celsius and should stay above 23.8 degrees. At night, the temperature can be as cool as 15.6 degrees. An 8.3 to 11.1-degree range in temperature during a 24-hour cycle is ideal. Humidity should stay at about 50 percent and not exceed 60 percent. To achieve this, humidity trays may be used and putting the plant in front of an open window is also helpful.

Potting and Fertiliser

As a general rule, while the Dendrobium orchid is growing or flowering, you should fertilise more often, about three times a month. In inactive months, you can fertilise just once a month. Soil should change every two years, unless the soil is not adequately draining; in this case, swap it out. Smaller pots are ideal, and once the orchid overgrows the pot, either switch it out to a new one, or divide it into multiple orchids.
