Dendrobium unicum

Also known as: Information to be completed

A miniature-sized, tropical orchid with clustered, 7-9cm long stems. Two to three, lance-shaped leaves 2-7cm long are carried near the tip of each stem. Short flowering stems emerge from upper nodes of leafed or leafless stems and carry two to four, bright orange-red flowers. Each upside-down flower measures 4-5cm. The lip is paler, with dark maroon, veined pattern.

Watering

Dry bark medium between watering, mist roots lightly in hot weather

Fertilizing

Weak orchid nutrient solution every three weeks growth period

Pruning

No pruning required. Remove spent flowers as necessary, but do not cut the whole cane unless completely shrivelled. Oldest canes may be removed as long as there are enough, younger, thick, leaf-bearing canes on the plant.

Propagation

Propagation by seed is only possible in controlled laboratory environment. Mature plants may be divided when the plant overgrows the pot. Sideshoots (keiki) may develop on older canes - remove and pot them into sphagnum moss when the new roots are at least 2cm long.

Growing

Plants are best grown mounted on cork bark or wood if sufficient humidity can be provided. Alternatively, grow in a basket in an epiphytic, medium grade, bark-based potting mix with added perlite, moss, or coir. As with many orchids, they grow best when the roots are slightly restricted. Therefore, avoid over-potting or frequent root disturbance. Provide bright light and sufficient humidity by misting regularly throughout the growing season. Reduce watering and feeding during the rest period in winter. For a successfull cultivation, the plant requires good air movement, and a significant drop of temperature between day and night time.
