IDENTIFY DENDROBIUM CRUMENATUM
Dendrobium crumenatum is native to Hong Kong, Taiwan, India, Sri Lanka, Andaman Islands, Myanmar, Thailand, Malaysia, Cambodia, Laos, Vietnam, Lesser Sunda Islands, Moluccas, Sulawesi, Sumatra, New Guinea, Christmas Islands and the Philippines. They usually grows on the upper branches of trees growing on not very exposed, semi-shady positions near damp, lowland areas, sometimes on the seashore. In Sumatra, this species are found near Padang-Padjand at an altitude of about 800 m, and in Borneo it can be found in Sabah in forests growing on hills at heights of 700-900 m. In Malaysia they are often found growing in orchards and on roadside trees, all over the peninsula. This orchid is widespread in the Philippines, where it grows at altitudes from sea level to around 500 m, usually on coconut palms or on other palm trees. They were also found in Sulawesi and on the island of Ambon, and the easternmost on the island of Bougainville.
It is a small to large sized, hot to warm growing epiphyte, which can reach a height of sometimes 5-8 cm, sometimes 60-92 cm, and even 152 cm, with spindle shaped, swollen basally for a few nodes, ridged, yellow with age stems that can branch, carrying, 4 to 19, thick, leathery, eventually deciduous, 5-8 cm long leaves.
The Pigeon Orchid will flower on the upper nodes of the leafless older canes with several to many fragrant flowers, albeit for only a few hours, after a temperature drop and rain. The flowers usually are 2.5-5.0 cm long, but their size is very variable. White flowers are shiny and may have a bluish or pinkish color. The lip has 5 bright yellow bulges.
DENDROBIUM CRUMENATUM CARE AND CULTURE
Dendrobium crumenatum blooms once a month during warm, dry weather, when evaporation from unexpected rain (or spraying in a greenhouse) cause a temperature drop of 6 ° C. Flower buds develop to a certain stage and expect a sudden drop in temperature, after which flowers develop over 9 days.
Light:
Dendrobium crumenatum needs a light level of 35000-45000 lux.
Temperature:
Throughout the year, the average day temperature is 30-34 ° C, the night 19-22 ° C, giving a daily difference of 8-14 ° C.
Humidity:
The Pigeon Orchid needs the average humidity of 80-85% for most of the year, and within 3 winter months it drops to 75-80%.
Substrate, growing media and repotting:
Dendrobium crumenatum can be grown on cork or tree fern rootstocks, but you should ensure high humidity and watering in summer at least once a day. When growing in pots, any loose, quickly drying ground is used. New increments begin to appear when the rains begin after the dry season and the new roots begin to grow when the new growths are partially mature. Repotting should be carried out immediately after the appearance of new roots.
Watering:
The Pigeon Orchid should be constantly moist from late spring until autumn, with a slight drying out between waterings. At the end of autumn, the amount of water should be gradually reduced.
Fertilizer:
It is recommended to apply weekly or every 2 weeks 1/4-1/2 doses of balanced fertilizer to orchids throughout the year.
Rest period:
Dendrobium crumenatum can tolerate even minimum winter temperatures of 15 ° C. Over the period of 2-3 winter months, water and fertilization during this period should be reduced, and plants should be allowed to dry slightly between waterings. However, they should not stay dry for too long.
