Dendrobium aphyllum orchid - Leafless Dendrobium has found in southern China, the eastern Himalayas, and Indochina as a large sized, hot to cool growing, epiphytic and occasional lithophytic species often refered to As D pierardii or D cucullatum
Dendrobium aphyllum orchid is a species of the Dendrobium genus. Several synonyms are known for this species such as: Limodorum aphyllum Roxb. (1795), (Basionym) Cymbidium aphyllum (Roxb.) Sw. (1799), Epidendrum aphyllum (Roxb.) Poir. (1810), Dendrobium cucullatum R.Br. (1821), Dendrobium pierardii Roxb. ex Hook. (1822), Dendrobium macrostachyum Lindl. (1830), Dendrobium tetrodon Rchb.f. ex Lindl. (1859), Dendrobium stuartii F.M.Bailey (1884), Dendrobium pierardii var. cucullatum (R.Br.) Hook.f. (1890), Callista aphylla (Roxb.)

(1920), Dendrobium whiteanum T.E.Hunt (1951), Dendrobium madrasense A.D.Hawkes (1963), Dendrobium aphyllum var. cucullatum (R.Br.) P.K.Sarkar (1984), Dendrobium aphyllum var. katakianum I.Barua (2001).
The species was discovered by William Roxburgh in southern India and described in his book Plants of the Coast of Coromandel in 1795. During most of the nineteenth and twentieth centuries, Dendrobium aphyllum was best known as D. pierardi, perhaps because the latter had been much better illustrated by Sir William Hooker in 1822. Under this name, it became one of the most widely cultivated Dendrobium species, a status that it still enjoys. Another name for this species, D. cucullatum, which was published in 1821 by Robert Brown, but until recently this had been almost forgotten. The correct name, D. aphyllum, only came into general use after 1985, when the influential Danish botanist Gunnar Seidenfaden confirmed, albeit with some reservations, that this was the same species that people were growing as D. pierardii. Gradually, the name D. aphyllum has come back into use and is the accepted name.
IDENTIFY DENDROBIUM APHYLLUM ORCHID
Found in southern China, the eastern Himalayas, and Indochina as a large sized, hot to cool growing, epiphytic and occasional lithophytic species often referred to As D pierardii or D cucullatum (and is a pink flower) that occurs at altitudes of 150 to 1800 meters in evergreen lowland forests and primary montane forests with slender, pendulous, leafy stems carrying linear-lanceolate or narrowly ovate, acuminate, deciduous leaves that blooms almost at any time of the year but the most common is in the winter and spring with a short inflorescence that arises from the nodes of older leafless canes having 1 to 3, fragrant, short-lived, fragile flowers, clustered close to the cane that are strongly scented of violets.
Identification: the cylindrical stem with 60 - 80 cm long, 0.4 - 0.5 cm thick. The leaves of the plant are pointed, with 6 - 8 cm long, 1.5 - 2 cm wide. The flower buds grow on the leafless stem. The flowers are light purple, 4 - 4.5 cm in diameter, peduncle and ovule are 2 - 2.5 cm long. Petals are pointed shaped, about 2.4 - 2.5 cm long, 0.6 - 0.7 cm wide. The lips are light yellow, with a funnel shape, 2.7 - 3 cm long, 2.5 - 2.6 cm wide.
GROW AND CARE DENDROBIUM APHYLLUM ORCHID
The best time to buy orchids for grafting is from the end of autumn to winter, when the leaves fall out and plant go to the rest season, so when graft, its does not have much care, only care when the spring begins to sprout new flower buds.
Preparation of materials cultivates for planting Dendrobium aphyllum orchid:
The most suitable cultivate is determined by the characteristics of the plant in nature. For the Dendrobium aphyllum species is the tree trunk has been completely peeled, will meet the full demand for water, airiness for orchids.
Material treatment: The woody material is completely peeled, soaked in water for 7 days, to allow the wood to absorb enough water, avoid the phenomenon of moisture absorption of orchids when grafted.
Pruning, cleaning Leafless Dendrobium:
When orchids are purchased, it is necessary to cut and remove the roots, root cut to 2-3cm. Root cuttings to remove the much damaged roots, and eliminate pathogens rooted in roots.
Time: need to prune early, preferably immediately after buying.
Treating and hanging backwards Dendrobium aphyllum orchid:
Leafless Dendrobium should be treated with medicine to eliminate pathogens, stimulate growth and prevent environmental shock for orchids.
Den. aphyllum is treated with a mixture of medicine: B1 + N3M + Ridomil gold + Alitte + Regan. As directed on the label, orchids are immersed in the medicine mixture for 5 minutes. Then pick up the hanging backwards the plant in about 3-5 days.
How to choose the environment of domesticated Dendrobium aphyllum orchid:
For Dendrobium aphyllum orchid, the best environment for domestication is the environment which have airy, the humidity is not too high (about 60-70%) and have relatively light (50-70% natural light).
Care for Dendrobium aphyllum orchid after grafted:
Watering: 3 - 7 days after grafting, do not water. Place the plant in a well-ventilated environment, the cultivate must always remain moist to cool the plant. If the plant is grafted during the holiday season, it is only necessary to irrigate the spray to keep the plant moist, avoid watering much.
Fertilizer application: the stage of germination but not root, fertilizer is not applied, because during this period the plant is absorbing nutrients accumulated in the old stem to produce the sprout without irrigation, new seedlings are too young so its easy to be rotten.
After the plant has reached new roots, we apply fertilizer 30-10-10 + TE grow more, dosage 1g / 4 liters of water, spray both sides of leaves, from April to October.
In August, spraying fertilizer 6-30-30 + TE grow more, dosage 1g / 4lit. After seeing the flower buds in the top, use fertilizer 20-20-20 + TE grow more.
From October onwards, do not fertilize and leave the plants completely under natural conditions.
Prevention: due to the environment always has orchid disease so we need to spray periodically: mix of Antracol + lino oxto + regan, periodically every 15 days.
From October to March of next year, do not spraying preventive medicine, due to this extreme conditions should be relatively less disease.
You also need to pay attention that the conditions for flowering are: the plant need 80% of natural light, stop completely watering plants in winter and early spring, apply fertilizer 6-30-30 in August, the environment of the plant must be enough dry and airy. Good luck!
