| Hi Hummer344:
In Southern California. the night temperature sometime drop to 40. most of my orchids survived except the phal. it failed but I have good louck on dendrobium phal , oncidium, cattaleya and cymbidium it slow down in winter but back to life when temperature rise in summer. some variety better than others. now after 15 years later all my orchids left are all cold temperature tolerant. |
