IDENTIFY DENDROBIUM SULCATUM
Dendrobium sulcatum is native to India and Southeast Asia, including Myanmar, China, northern Thailand, Laos and Vietnam. In India, their natural habitats extend from the tropical valleys near Kalimpong and Darjeeling in Sikkim to the Khasi Hills (Khasia), Assam, Manipur and Megahalaya. In north-eastern India, they grow at heights of 500-1000 m.
It is a small to medium sized, warm growing epiphyte, which reaching 20-45 cm in height, that has flattened, 25 cm long, clavate pseudobulbs carrying 2 apical, ovate, 10-20 cm long leaves.
The Furrowed Lip Dendrobium blooms in the late spring on a short, pendulous inflorescence produced below the apical leaf and is not much longer with very short lived, fimbriate flowers. The flowers are 2.5-3.5 cm in diameter and have a shape similar to bowls or bells. The flakes of both whorls may be bright or faded yellow or orange-yellow with darker lines. The orange lip has red veins and brown or red-brown nerve veins on both sides at the base. The ruffle has a boat shape, it seems to be folded and has hairs along the banks. At the top, there are small, pincer-like appendages.
DENDROBIUM SULCATUM 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 sulcatum needs a light level of 25000-35000 lux.
Temperature:
The average summer temperature is 28-29 ° C, night 22 ° C, giving a daily difference of 7 ° C. The average temperature of the winter day is 21-27 ° C, the night 7-12 ° C, which gives a daily difference of 13-14 ° C.
Humidity:
For most of the year, The Furrowed Lip Dendrobium needs the humidity of 80-85%, but within 3 months at the end of winter it drops to 65-70%.
Substrate, growing media and repotting:
Dendrobium sulcatum can be grown mounted on tree-fern rootstocks or cork, with high humidity and watering in summer at least once a day. If they are grown in pots, any loose, fast-drying substrate is recommended. Repotting can be performed in any period as soon as new roots grow.
Watering:
During the growing season from spring to early autumn, the rainfall is abundant, but it is dry during the 2-3 winter months. In spring and summer, the plants should be constantly moist but not soaked, and 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. It is preferable to use high-nitrogen fertilizer from spring to mid-summer, and then use high-phosphoric fertilizer until the end of autumn.
Rest period:
A cold, dry rest period is usually necessary to induce flowering of Dendrobium sulcatum. The amount of water should be reduced for the period of 2-3 winter months. They should dry out between waterings, but they can not stay dry for a longer period. Fertilization should be reduced or eliminated until spring, when regular watering is resumed.
