Dry Winter Rest
Dry winter rest is something that happens every winter in order for certain types of orchids to stay healthy and provide blooms in the coming spring. Usually it takes place from Halloween till Valentines day where we do not water these orchids unless it shows sign of shriveling (should be at least once or twice, if not none.)The orchids that needs these dry winter rest are to my knowledge the Dendrobium Nobile. The rest of the rest of the other Dendrobiums as far as I know are allowed to be waters throughout the season without any problems. There are some people out there that does provide dry winter rest for these orchids, but it is absolutely not necessary.
