IDENTIFY DENDROBIUM CHRISTYANUM
Dendrobium christyanum is native to North Thailand, Vietnam and southwestern China. This plants occur in colder forests at an altitude of approximately 1220 meters above sea level.
It is a miniature to small sized, warm to cool growing, miniature epiphyte, which can reach the height of 8-14 cm, with caespitose, subclavate, abbreviated, 5-8 cm long pseudobulbs enveloped by 3 to 4, pellucid sheaths covered in black hairs and carries 2 towards the apex, lanceolate, obtuse, covered in black hairs below, obliquely bilobed apically, 3-6 cm long leaves.
Christy's Dendrobium blooms in the late spring and summer on a terminal or lateral, very short, single flowered inflorescence that arises from the apex or on the sides of old and new pseudobulbs and carries fragrant flowers. The flowers are 5 cm in diameter, which means they are very large in relation to the whole plant. They are creamy white. The broad, violin-shaped lip has a bright orange-yellow spot in the center. The lip does not bend down at the end.
DENDROBIUM CHRISTYANUM 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 christyanum needs a light level of 25000-40000 lux and dispersed light is recommended. The light should be very bright, but direct sunlight should be avoided. The air movement is useful.
Temperature:
The average temperature of the summer day is 25-27 ° C, the night 18-19 ° C, giving a daily difference of 7-9 ° C. In spring, the average day temperature is 29-30 ° C, the night 11-18 ° C, which gives a daily difference of 11-18 ° C. In winter the average day temperature is 24-27 ° C, night 8-9 ° C, giving a daily difference of 15-18 ° C.
Humidity:
Christy's Dendrobium needs a humidity in the summer and early autumn of almost 80%, in winter it drops to 65-75%, and at the beginning of spring for 2 months it is only 60%.
Substrate, growing media and repotting:
Dendrobium christyanum can be grown mounted on tree-fern rootstock or cork, providing high humidity and summer watering at least once a day. When growing in pots, use any loose, quickly drying ground. You can repot at any time as soon as new roots grow.
Watering:
Water is abundant from spring to early autumn, i.e. during the growing season. During this period, cultivated plants should be abundantly watered with a slight drying between watering. When new growths reach maturity in autumn, the amount of water should be gradually reduced.
Fertilizer:
It is recommended to apply a 1/4-1/2 dose of orchid fertilizer weekly. From spring to mid summer, fertilizer with an increased nitrogen content is preferred, and fertilizer with an increased content of phosphorus should be used at the end of summer and autumn.
Rest period:
A cool, dry rest is very important for Dendrobium christyanum and should last until new growths appear in the spring. You can eliminated water in winter, but the plants survive this period better, if they dry between watering, not staying dry for too long. At the end of winter, for 1-2 months, the plants should dry completely between waterings and stay dry longer. Occasional morning haze between watering will avoid excessive drying. Fertilization should be significantly reduced or eliminated until spring, when regular watering is undertaken.
