Orchid Dendrobium Care

Dendrobium (pronounced den-DROH-bee-um) is a diverse genus of orchids with different cultural needs. These orchids are noted for their upright, branching sprays of brightly colored flowers in a wide range of colors, sizes, and shapes. Once the first flower bud opens, the sprays will remain in bloom for the next 2 months. If the plant is kept in a bright warm spot, the plant may produce subsequent sprays of flowers.

Dendrobium Light
Sufficient lighting is must for successful cultivation. These orchids prefer either an east or a lightly shaded south facing window. Dark green leaves are an indication of insufficient lighting.

Dendrobium Temperature
Provide nighttime temperatures of 60 to 65°F and daytime temperatures of 70 to 90°F. These orchids prefer a difference in temperature between the night and day to aid in blooming.

Dendrobium Water
They should be watered about once or twice a week. Keep evenly moist while in active growth, and allow to dry between waterings

Dendrobium Humidity
They prefer 50% to 60% humidity. This can be provided in the home by placing the plants on trays of gravel, only partially filled with water so that the plants do not sit in the water.

Dendrobium Feeding
They prefer to be fertilized on a regular basis. A general rule is to apply a balanced fertilizer ‘weakly, weekly’ during the period of active growth by fertilizing every week at one quarter to one half of the recommended dilution. It’s important to flush with clear water once a month.

Dendrobium Potting
Repotting should be done every two to three years before mix breaks down. Ideally, they should be repotted in the spring. They do best when grown in pots that are small for the size of the plant.
