IDENTIFY DENDROBIUM VIRGINEUM
Dendrobium virgineum is native to Myanmar, Laos, Cambodia, Vietnam and eastern Thailand. In Thailand, these orchids are found near Seta, Nongkhai, Ubon Ratchathani, Nakon Phanom and in the Phu Won National Park. They grow in highland primary cloud forests at elevations below 1600 meters.
It is a medium sized, warm to cool growing epiphyte, which reaching 30-40 cm in height, with slender, cylindrical, medially swollen, 30-40 cm long stems that are tapering at both ends carrying many, oblong to elliptic-ovate, deep green, flat, bilobed apically and covered in black hairs, 6.5 cm long leaves.
The Virginal White Dendrobium blooms on a short, racemose inflorescence arising from the nodes near the apex of the stem carrying 4 to 6 flowers occurring in the late summer and fall. The flowers are about 4 cm in diameter. The flakes of both whorls are pure white. The dorsal petal has a low bulge at the back. The slightly lance-shaped petals of the outer whorl are sharp and the broadly oval petals of the inner whorl are more rounded. The 3-pointed lip has an orange spot in the middle. Red venation on the lip is variable, as well as the presence of a red discoloration that can pass down the spur. The middle plot is almost round, indented at the top and has a wavy edge.
DENDROBIUM VIRGINEUM 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 virgineum needs a light level of 25000-35000 lux. Shading is needed from spring until autumn, but the light level should be as high as possible, so as not to let the leaves burn.
Temperature:
The average temperature of the summer day is 31-32 ° C, the night 23-24 ° C, giving a daily difference of 7-8 ° C. In spring, the average day temperature is 33-35 ° C, night 21-24 ° C, giving a daily difference of 10-12 ° C. The average temperature of the winter day is 28-29 ° C, the night 13-17 ° C, giving a daily difference of 13-15 ° C.
Humidity:
From the end of spring to autumn, The Virginal White Dendrobium need the humidity of almost 80%, in winter and at the beginning of spring it drops to almost 60%.
Substrate, growing media and repotting:
Dendrobium virgineum can be mounted on tree fern washers with high humidity ensured and watering is carried out at least once a day in summer. When growing in pots, any loose, quickly drying substrate is recommended. Repotting is best done at the beginning of spring, when new roots grow.
Watering:
From the end of spring until the beginning of autumn, the precipitation is abundant, but from late autumn throughout the winter it is very dry. The cultivated plants should be constantly moist from the end of spring and summer, but in autumn, when new growths reach maturity, the amount of water should be gradually reduced.
Fertilizer:
In the period of active spring growth, it is recommended to use 1/2 doses of different fertilizers for orchids every week. From spring to mid-summer, high nitrogen fertilizer should be used, especially when the base is bark, and then until the end of autumn high phosphoric fertilizer to improve flowering and allow new growths to mature before winter.
Rest period:
In winter, Dendrobium virgineum should dry out between waterings, but they can not be dry for too long. Occasional morning fogging between waterings will not allow the plants to be dried out too much. Fertilization should be reduced or even eliminated until spring, when more watering resumes.
