The thick leaves of this orchid won't freeze until the temperature reaches 27 degrees F but the flower buds are damaged at 32 degrees F. Its actually cooler temperatures that stimulate Cymbidiums to bloom. They bloom from November to January, but the blossoms are set many months before that. During spring, greenhouse growers will drop the temperatures around the plants to about 55 degrees for several days in a row, and then raise daytime temperatures each day to about 80 degrees. Its this 25 degree temperature difference that produces blooms. These blooms can last for many months.
Cymbidiums work well in small pots.
They like their roots to be crowded. Their soil mix is acidic and consists of perlite, some peat. The mix must drain very quickly. Orchids need bright, indirect light. During winter, you can place the plants in direct sun since the days are much shorter and the suns rays much weaker.
