Dendrobiums are an excellent choice for the novice grower. Flowers are available in a wide range of colors, sizes and shapes. From the time that 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. Please follow the guidelines provided for successful cultivation.
Lighting
Sufficient lighting is must for successful cultivation. Dendrobiums prefer either an east or a lightly shaded south facing window. Dark green leaves are an indication of insufficient lighting.
Temperature
Provide nighttime temperatures of 55 to 60°F and daytime temperatures of 70 to 90°F.
Watering
Depending upon the temperature, Dendrobiums should be watered about once or twice a week. During the summer, the plants may need to be watered every 4-5 days. The rule of thumb for watering should be as followed: More heat more water, less heat less water.
Dendrobiums must be allowed to dry out completely in between watering. Try to water the plants early in the day, so that the foliage will be dry by nightfall. To prevent bacterial and fungal disease use Physan 20 once a month.
Humidity
Dendrobiums prefer 40% to 50% humidity. Humidity Trays may be needed, especially if a heater or air conditioner is in use in the house.
Fertilizer
Dendrobiums must be fertilized on a regular basis! For best results, use Norman's Optimal Orchid Nutrients every other week. It is recommended to pre-water plants, before applying the diluted nutrient solution if the potting media is dry.
Potting
Dendrobiums should be grown in Medium Orchid Bark Mix and should be repotted once every two years. Ideally, Dendrobiums should be repotted in the spring. Dendrobiums do best when grown in pots that are small for the size of the plant.
Pests
Common pest associated with Dendrobiums are scale, mealy bugs and spider mites. X-CLUDE, encapsulated pyrethrum time-release insecticide, and Neem Oil are the most efficient methods of pest control.
