Growing habits
Dendrobium aurantiacum Rchb. f. is a kind of hi perennial herbs like hi, like in the warm, humid, annual rainfall of more than 1000 mm, half-shade half-Yang environment, the average January temperature above 8 ℃ in the growth of subtropical forests is better , Suitable for growing temperature of 15 to 28 degrees, suitable for growing air humidity above 60%, less demanding on soil fertility, wild and more in the loose and thick bark or trunk growth, and some also grow in the crevice. Is an aerial root, the main requirements of the root permeability is good, the best substrate to breathe air ventilation, in the appropriate temperature and humidity, fast growth, survivability is very strong. Spring and early summer each year, biennial stems on the section of the inflorescence, flowering stems grow into new stems into stems, autumn and winter into the dormant period.
