Dendrobium goldschmidtianum also called as Goldschmidt's Dendrobium, Dendrobium hainanense, Dendrobium irayense, Dendrobium miyakei, Dendrobium pseudohainanense, Dendrobium victoria-reginae var miyakei, Pedilonum goldschmidtianum, Pedilonum miyakei, is a species of the genus Dendrobium. This species was described by Friedrich Fritz Wilhelm Ludwig Kraenzlin in 1909.
IDENTIFY DENDROBIUM GOLDSCHMIDTIANUM ORCHID PLANT
Dendrobium goldschmidtianum is found in Thailand and the Philippines. It grows epiphytic in ficus trees in the banyan jungles at an altitude of about 300 meters above sea level.
It is a medium to large sized, hot to warm growing epiphyte with clustered, unbranched, cane-like, 60-80 cm long and 1-2.5 cm wide stems carrying many, deciduous, linear-lanceolate, pointed, 8 cm in length and 3-3.5 cm in width leaves.
Goldschmidt's Dendrobium blooms in the late winter and early spring and a secondary bloom can occur in the later summer and early fall on a short, fasciculate, racemose, few to several flowered inflorescence that arises from the nodes all along the older leafless cane with 4 to 8, small, fragrant flowers held in a cluster. The flowers are pink in a lighter strip, about 1.3-2 cm in diameter. Sepals lanceolate, lateral larger and 1/3 fused together. Petals several already, but more striped. The lip is triple.
DENDROBIUM GOLDSCHMIDTIANUM 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:
Dendrobium goldschmidtianum loves the bright sun and can tolerate direct sunlight (up to 70000 lux), acquiring a reddish shade of leaves and pseudobulbs. The southern, south-western, western and south-eastern windows are considered to be the ideal location. On pure eastern and northern windows, the orchid usually builds up longer pseudobulbs, but irregularly blooms (or does not bloom at all), therefore, in addition to natural light, artificial light lamps should be used here . The total duration of a light day should be at least 10-12 hours, preferably 16 hours.
Temperature:
This type of orchid refers to a moderately warm temperature regime, and throughout the year the plants are recommended to contain under the following conditions: Day temperature at 18-30 ° C; Night temperature is not below 12 ° C. For the successful cultivation at home, it is necessary that the night temperature of the contents always be at least 4 ° C lower than the daytime temperature.
Humidity:
In their natural habitats, 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 goldschmidtianum is grow only in pots or hanging baskets. As a substrate, it is desirable to use a mixture of the bark of coniferous trees with charcoal, peat and sphagnum moss, and to impart greater stability as a drainage, granite pebbles are put. In the event that the planting on the block does not bother you, then it is desirable to use a large piece of bark as the block itself, and to place a small cushion of sphagnum from above (to prevent rapid drying) of the roots.
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 the time when new sprouts begin to build up 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 well, but not more than 2 days is completely dry, it is desirable that the roots of the orchids are always slightly moistened.
Fertilizer:
During active growth, this type of orchid is fertilized once a month in 1/2 of the fertilizer concentration indicated on the package. In addition to the usual root top dressing, it is also recommended to produce a foliar dressing, when a very much diluted fertilizer is sprayed on the outer part of the plant. It is best to feed the plant, 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 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 - a fertilizer with a higher content of phosphorus and potassium.
Rest period:
Dendrobium goldschmidtianum does not have any period of rest: neither for stimulation of flowering, nor in winter. In conditions of sufficient illumination, the plant is able to grow the green mass all year round and, at the end of the formation of new pseudobulbs, discard leaves from old and blossom. Refusal of flowering can be caused by the general weakened state (absence of the root system completely), too hot content or insufficient illumination.
