Dendrobium gibsonii is native to China (Guangxi and Yunnan provinces), the Himalayas (Nepal, Bhutan, India, Assam), and northern Indochina (Myanmar, Thailand, Laos, Vietnam). It grows on tree trunks in open forests at elevations of 650 to 1650 meters.
Dendrobium gibsonii also called as Gibson's Dendrobium, Callista binocularis, Callista gibsonii, Dendrobium binoculare, Dendrobium fuscatum, Stachyobium aureum, is a species of the genus Dendrobium. This species was described by Joseph Paxton in 1838.
IDENTIFY DENDROBIUM GIBSONII ORCHID PLANT
Dendrobium gibsonii is native to China (Guangxi and Yunnan provinces), the Himalayas (Nepal, Bhutan, India, Assam), and northern Indochina (Myanmar, Thailand, Laos, Vietnam). It grows on tree trunks in open forests at elevations of 650 to 1650 meters.
It is a large sized, warm to cool growing epiphyte or lithophyte on mossy limestone cliffs with centrally swollen, tapering towards the apex, pendulous, ribbed stems carrying 6 to 10, ovate to lanceolate, acute, deciduous leaves.
Gibson's Dendrobium bloom in the spring and summer on a slightly fractiflex, nodding to pendulous, 15 to 20 cm long, loosely 6 to 15 flowered inflorescence arising on older leafless canes. The flowers are deep yellow in colour, the labellum being rather deeper in shade, downy and ornamented with a double maroon blotch towards the back of the middle lobe. It is slightly fringed on the curling sides. It has a strong, rather musty, scent.
DENDROBIUM GIBSONII ORCHID PLANT CARE AND CULTURE
Cultural information should only be used as a guide, and should be to be adapted to suit you. Your physical location; where you grow your plants, how much time you have to devote to their care, and many other factors, will need to be taken into account. Only then can you decide on the cultural methods that best suit you and your plants.
Light:
Dendrobium gibsonii like plenty of light (25000-50000 lux, better in bright, diffused light) but not direct sun's rays, except in the early morning. The light level should be as high as possible, which the plant can tolerate without scalding the leaves.
Temperature:
The average temperature of the summer day is 25-26 ° C, night 21 ° C, giving a daily difference of 4-6 ° C. In winter, the average day temperature is 27-30 ° C, night 16-17 ° C, giving a daily difference of 13 ° C.
Humidity:
From summer to autumn, Gibson's Dendrobium need the humidity of 80-85%, but for most of the remaining period it drops to 60-70%. Too dry air has a negative effect on the development of the plant: its growth is inhibited, and the leaves begin to turn yellow and dry out. The higher temperature, the higher the humidity should be, and the higher the humidity, the more often and longer it is necessary to ventilate the room where the plants are contained, otherwise the probability of rotting and various kinds of fungal diseases.
Substrate, growing media and repotting:
Dendrobium gibsonii grows best in pots with staghorn peat as substrate (crocks and charcoal at the bottom of the pot). After potting, keep the plant in a cool, shady place for a few days before placing it in its growing position. Do not overpot. Use the smallest pot that will accommodate your plant.
It does not need frequent repot, therefore, it is desirable to transplant only when it is really necessary, for example, in cases of strong salinization or compaction of the substrate, at its critically high or low pH (the norm is from 5.5 to 6.5) or when the plant grows very strongly and the pot becomes cramped to it (pseudobulbs begin to hang from the edges of the pot). Repotting is best done immediately after flowering when new roots and new growth begin to grow.
Watering:
Gibson's Dendrobium will require heavy watering until well into the Autumn, the plants then being allowed to dry out for the Winter, except for a soaking about once in four to six weeks. Watering is directly dependent on the temperature of the content, the higher it is, the more often it needs to be watered. When watering, excess water should flow freely from the pot, since stagnation of water both inside the pot and in its pan can very quickly lead to rotting of the roots and the lower part of the plant.
Fertilizer:
It is recommended to use a 1/4-1/2 dose of orchid fertilizer weekly. You can use the balanced fertilizer throughout the year or from spring to mid-summer use high-nitrogen fertilizer, and then until the end of autumn high-phosphoric fertilizer to stimulate flowering.
Rest period:
Dendrobium gibsonii need less water in the winter, especially if they grow under the conditions of a dark, short day that occurs at moderate latitudes. They should dry somewhat between waterings, but they should not be dry for a longer period. Frequent morning fogging and rare, economical watering should allow the plant to go through a dry period of rest, while providing it with sufficient humidity. Fertilization should be reduced or eliminated until new growths appear and a more abundant spring watering begins.
