There are deciduous and evergreen types of Dendrobium. Unfortunately, I could not find information about the variety you are growing. If yours has soft canes, it is deciduous; hard canes are characteristic of the evergreen type. Here is information from Orchids Made Easy<\/a>:
\n“Dendrobiums are separated into two main groups: hard-caned and soft-caned.
\nHard-caned Dendrobiums have tall pseudobulbs that are very thin and their leaves are generally a little darker in color than the soft-caned. Hard-caned Dens are evergreen and often keep their leaves for many years before they drop them. Hard-caned Dens grow spikes from the top of the cane and produce gorgeous flower sprays.<\/p>\n

“Soft-caned Dendrobiums have leafy pseudobulbs that are long and slim. Their leaves are generally a little lighter in color than the hard-caned Dens. They grow leaves along the length of the cane and the blooms sprout from the individual stems that are along the cane itself. Soft-caned dendrobiums are deciduous and drop their leaves
\nwhen the weather gets cold.”<\/p>\n

The American Orchid Society<\/a> has a guide to growing evergreen<\/em> Dendrobium for beginners.<\/p>\n

There is also good general information on caring for orchids in the Brooklyn Botanic Garden<\/a> guides<\/a> on the subject. Generally, winter is the time to hold back on watering a bit, but also be careful about the plant’s need for humidity–our heated homes in winter can be exceedingly dry. According to Orchids<\/em> by Joyce Stewart (Timber Press, 2000), most orchids prefer 65-75% humidity during the day. She recommends “damping down last thing at night” during the winter (using a spray bottle or mister), if you have heat on in your house overnight.<\/p>\n
