IDENTIFY DENDROBIUM CHRYSANTHUM ORCHID
This large sized, warm to cold growing epiphyte, lithophyte on limestone cliffs in narrow crevasses and terrestrial species is widespread through the Himalayan foothills of the western Himalayas, Assam India, China, Nepal, Bhutan, Sikkim, Myanmar, Thailand, Laos and Vietnam in humid, mossy, mixed and coniferous forests and primary, broadleafed, evergreen, lowland forests at elevations of 350 to 2200 meters with pendulous, many noded, sulcate, to 5' (150 cm) long stems carrying ovate-lanceolate, acuminate, bright shiny green leaves that blooms from April till November on an axillary, very short, opposite of leaves, few to several flowered, racemose inflorescence that arise on the nodes on the upper portion of an immature leafed pseudobulb. The inflorescence arises opposite of the leaves with 1 to 3 fragrant, fleshy flowers and needs a drier winter rest to set the blooms for the following spring.
Identification: the cylindrical stem with 70 - 160 cm long, 0.6 - 0.8 cm thick. The leaves of the plant are pointed, with 10-16 cm long, 3 - 4 cm wide. The flower buds grow on the stem that still remain leaves. The flowers are yellow, 4 - 4.5 cm in diameter, peduncle and ovule are 4 - 5 cm long. Petals are egg shaped, about 2.3 - 2.4 cm long, 1.4 - 1.5 cm wide. The lips are yellow, with a funnel shape, 2.6 - 2.8 cm long, 2.3 - 2.4 cm wide, with 1 or 2 reddish spots in the middle.
GROW AND CARE DENDROBIUM CHRYSANTHUM ORCHID
Dendrobium chrysanthum orchid should be selected when the plants are in deciduous period, undeveloped or have new roots, this period is usually around early winter when the flowers are withered about 10-20 days. Plants at this time have accumulated a lot of nutrients in the stem, which is a favorable condition to grow fast and strong in spring.
Preparation of materials cultivates for planting Dendrobium chrysanthum orchid
The most suitable cultivate is determined by the characteristics of the plant in nature. For the Dendrobium chrysanthum 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 Golden yellow flowered 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 chrysanthum orchid:
Golden yellow flowered Dendrobium should be treated with medicine to eliminate pathogens, stimulate growth and prevent environmental shock for orchids.
Den. chrysanthum 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 chrysanthum orchid:
For Dendrobium chrysanthum 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).
Grow and care Dendrobium chrysanthum 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.
At the end of 3-7 days, we perform irrigation, because the nature of plants do not like too much water, so water 1-2 times per day, watering only the cultivate. Periodically, on Sundays, water the plants, irrigate the plants 3 times, each time for 5 minutes, water the whole plant and the cultivate.
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.
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.
You also need to pay attention that the conditions for flowering are: pure natural light, stop completely watering plants in winter, apply fertilizer 6-30-30 in August, the environment of the plant must be enough dry and airy. Good luck!
