The plant carries deciduous, strap-shaped or oblong-lance shaped, pointed to blunt leaves. It blooms in the winter, spring and summer on a lateral, short, few to several, long-lived, sometimes fragrant, flowered inflorescence that arises from the nodes on 2 to 3-year-old leafless canes.

Habitat of Dendrobium Heterocarpum
The plant grows in warm to hot temperatures with medium amounts of light. Keep plants moist and fertilize during the growing season. During winter reduce watering until new shoots appear. Grow in a good drain mix of sphagnum moss or medium fir bark.
Dendrobium heterocarpum are happy to bloom and may bloom at any time of the year except the start of summer. In Indonesia, they bloom at the top of autumn and at the start of winter. From other areas, they bloom in spring. they typically bloom in very bright light, until the trees cover the leaves. it's a well-liked plant and simply adapts to the created conditions.
Light:
Dendrobium heterocarpum needs a lightweight level of 30000-40000 lux. the sunshine should be naturally filtered from spring to autumn, but its level should be as high because the plant can tolerate it without scalding the leaves.
Temperature:Den.heterocarpum
the typical temperature of the summer day is 25-26 ° C, the night 17-18 ° C, giving a daily difference of 7-8 ° C. In spring, the typical day temperature is 29-31 ° C, the night 11-18 ° C, giving a daily difference of 11-20 ° C. In winter the typical day temperature is 23-30 ° C, night 8-11 ° C, giving a daily difference of 14-20 ° C.
Humidity for Dendrobium heterocarpum
From summer to autumn, the various Fruit Dendrobium need the humidity of 80-85%, and in winter it drops to 60-70%. During the 2 spring months, however, the conditions are very dry and therefore the humidity drops to almost 50%.
Growing media and repotting:
Dendrobium heterocarpum is simpler to grow mounted on tree ferns or cork or in hanging, small pots or baskets. When growing in pots, any loose, quickly drying media is suggested. Repotting is best done at the start of spring when new roots begin to grow. Flowers may appear on 3-year-old shoots, in order that they shouldn't be removed when repotting.
Watering for Den. heterocarpum
Precipitation is extremely abundant during the season, but winters are very dry. Dendrobium heterocarpum require frequent and abundant watering during the season, but when new growths reach maturity in autumn, the quantity of water should be gradually reduced.
Fertilizer for Den. heterocarpum
it's recommended to use a 1/4-1/2 dose of orchid fertilizer weekly. From spring to mid-summer, it's preferable to use high-nitrogen fertilizer, then to the top of autumn, high phosphorus fertilizer.
Rest period of Den. heterocarpum
Water should be reduced from the top of autumn to spring. for many of winter, Dendrobium heterocarpum should dry out between watering, but they will not be completely dry for too long. Occasional morning fogging between watering will protect the plant against excessive drying. within the period of 1-2 months at the top of winter, however, the quantity of water should be limited to morning fog. Fertilization should be reduced or eliminated until new growths appear within the spring.
