IDENTIFY DENDROBIUM GRACILICAULE
Dendrobium gracilicaule is native to Eastern Australia. The natural habitat stretches from Kiama in the state of New South Wales to the north as far as Cairns near the Bloomfield River in Queensland. These plants usually grow on trees in shady forests, but sometimes they are found on rocks, in coastal shrubs and in open forest spaces, often in full sun. In the northern part of the habitats, they are found only in the mountains and on the plateaus.
The Delicate Stems Dendrobium is a medium to large sized, hot to warm growing epiphytic and sometimes lithophyte species, which reaching 25-74 cm in height, with erect, basally swollen, cylindrical, greyish, 20-60 cm long stems carrying 3 to 6, lanceolate to ovate, acuminate, thin textured, 5-13 cm long leaves.
The Blotched Cane Orchid blooms in the late winter and spring as younger plants and becoming free-flowering with age on a drooping 5 to 40, fragrant flowered inflorescence arising from the nodes near the apex of mature canes. The flowers are 1.3-2.6 cm in diameter. The petals of both whorls are creamy to dark yellow, they also usually have significant red-brown spots on the outer whorl flakes. The yellow lip has red-brown spots. It is straight, curved and has a kidney shape with 3 bulges on the dial.
DENDROBIUM GRACILICAULE 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 gracilicaule needs a light level of 25000-45000 lux. The light level should be as high as the plant can tolerate without burning the leaves. The plants growing in full sun, exposed to high levels of light are smaller, while those growing in more shadowy conditions are larger.
Temperature:
The average temperature of the summer day is 26 ° C, the night 16-17 ° C, which gives a daily difference of 9-10 ° C. The average temperature of the winter day is 16-21 ° C, and the winter night is 6-9 ° C, giving a daily difference of 11-12 ° C.
Humidity:
The Yellow Cane Orchid needs the humidity of 60-65% throughout the year. You need to ensure strong air movement throughout the year.
Substrate, growing media and repotting:
Dendrobium gracilicaule grow best on rootstocks made of cork or other hardwood. Mounted plants require daily watering and high humidity in the summer. If they are grown in pots, ceramic pots are better, they should be as small as possible and a fast-drying substrate and perfect drainage are recommended. Repotting is best done just after flowering.
Watering:
Precipitation is moderate in summer and autumn, but the winter is a bit drier. In cultivation, the delicate roots of Dendrobium gracilicaule are easily damaged by excessive watering. They must dry out between waterings, in addition, excellent ventilation is required.
Fertilizer:
It is recommended to apply a 1/4-1/2 dose of orchid fertilizer weekly. High-nitrogen fertilizer is beneficial from spring to mid-summer, and then use high-phosphoric fertilizer. The plants should be stimulated to the maximum growth in summer.
Rest period:
Dendrobium gracilicaule is often considered difficult to grow. The clear seasons are particularly important for plants. A cold, dry winter is very important. In winter, nighttime temperature should not be below 2 ° C. From mid-autumn until the emergence of new growths in spring, the amount of water should be significantly reduced. When new growths reach maturity in autumn, the fertilization should be reduced or eliminated.
