Dendrobium mohlianum also called as Mohl's Dendrobium, Chromatotriccum mohlianum,; Dendrobium mohlianum subsp. kolombangaricum, Dendrobium neo-ebudanum, Dendrobium vitellianum, Pedilonum mohlianum, Pedilonum neoebudanum, Pedilonum vitellinum, is a species of the genus Dendrobium. This species was described by Heinrich Gustav Reichenbach in 1862.
IDENTIFY DENDROBIUM MOHLIANUM ORCHID PLANT
Dendrobium mohlianum is found in Indonesia, Papua New Guinea and near the adjacent islands, where it grows in montane and cloud forests from 450 to 3100 m above sea level.
It is a medium to large sized, cool to cold growing species with clustered, slender, spreading or pendant, basally lightly swollen, leafy towards the apex, 40 cm long and 1-1.2 cm wide stems carrying many, distichous, lanceolate, , 8-9 cm in length and about 3 cm in width leaves.
Mohl's Dendrobium blooms from late winter through spring and early summer on 4.5 cm long, few to several flowered racemes that arise axillary towards the apex of older leafless canes with 4 to 6 flowers. The flowers are red-orange with a darker lip, 2-3 cm in diameter.
DENDROBIUM MOHLIANUM ORCHID PLANT 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:
The choice of the location of the Dendrobium mohlianum is perhaps the most difficult in its care, since, on the one hand, it is very sunny in the natural climate, and on the other - cool (mountains). In the rays of direct sun from the south and west side it is too hot, and in the east - too dark. As practice has shown, this orchid grow well from the southeast side and on the northern windows. In conditions of greenhouses, such problems are rare, since in conditions of high air humidity this plant can perfectly tolerate almost any heating.
Temperature:
This kind of orchid refers to the moderately cold temperature regime, and throughout the year the plants are recommended to contain under the following conditions: Summer temperature ideally not more than 20-22 ° C (it can tolerate higher temperatures, but this is very individual and varies greatly from specimen to specimen); Winter temperature at 16-18 ° C in the daytime and 10-12 ° C at night. For the successful cultivation at home, it is necessary that the night temperature of the content is always at least 4 ° C lower than the daytime temperature.
Humidity:
In their natural habitat, the relative humidity of the air rarely falls below 50%. In conditions of high humidity, it is necessary to regularly ventilate the room where the plants are kept, since wet, stale air is an ideal medium for the mass reproduction of various fungal and bacterial diseases.
Substrate, growing media and repotting:
Dendrobium mohlianum can be grow in pots and hanging baskets and placed on blocks. The mixture of a large bark of coniferous trees with peat (about 20%) and sphagnum moss is best as a substrate, and sphagnum has also proved to be quite good. When growing orchids on blocks to prevent rapid drying of the root system of the plant, it is recommended to make a small interlayer of moss between it and the block. Above the roots, you can also put live or dry sphagnum.
Repotting is desirable only when it is really necessary, for example, in cases of severe salinization or condensation of the substrate, at its critically high or low pH (norm from 5.5 to 6.5) or , when the plant will grow very much and the pot will become too small for it (pseudobulbs will begin to hang from the edges of the pot). The best time to transplant is when new orchid sprouts reach a size of 2-5 cm and begin to build their own roots.
Watering:
The frequency and abundance of watering the orchids of this species directly depends on the overall temperature of the content and intensity of the illumination, the higher they are, the more often and abundant it is necessary to water. Plants growing on blocks, it is desirable to water daily in the morning, so that by evening their roots could dry out relatively well. When watering orchids in pots, it must be remembered that excess water during watering should flow freely out of the pot, as the stagnation of water both inside the pot and in its pallet can quickly lead to decay of the roots and the lower part of the plant (rhizome). The substrate between waterings should dry relatively well, but do not dry out completely, i.e. is always in a slightly moistened, but not wet state.
Fertilizer:
During the period of active growth, this kind of orchids is fertilized for every third watering in 1/2 of the fertilizer concentration indicated on the package. In addition to the usual root top dressing, it is also possible to produce foliar dressing when the outer part of the plant (leaves) is sprayed very much with the diluted fertilizer. It is best to feed the orchid, alternating both these methods. The best fertilizer is fertilizer containing nitrogen, phosphorus and potassium in equal parts, for example, NPK = 3-3-3 or 8-8-8. If you do not have such a fertilizer, then at the beginning of the growing season (the emergence of new shoots), feed the orchid with a fertilizer with a high nitrogen content, and when the sprout reaches 1/2 of its normal growth - fertilizer with a higher content of phosphorus.
Rest period:
In winter, the intensity of light decreases slightly, but there is no complete stop in the growth of Dendrobium mohlianum, and watering is organized so that the substrate does not just dry out very well, but also 3-4 days was completely dry. Refusal to flowering can be caused by too hot content (regular overheating of orchids), absence of a difference between night and day temperatures, poor lighting or common stress state (for example, poor root system).
