TEMPERATURE:
THE IDEAL TEMPERATURE
To produce beautiful, long-lasting blooms, orchids must produce energy in the form of carbohydrates
during the day when the temperature is high, then store that energy at night when the temperature drops.
This temperature fluctuation is necessary for orchids to bloom. Without a day-night fluctuation of 10-15
degrees Fahrenheit, the plants will grow plenty of healthy foliage but may stubbornly refuse to flower. A
night temperature of 60-62 degrees F is ideal for optimum growth, but temperatures as low as 55 degrees
F will not harm your plant. Daytime temperatures should range between 70 and 80 degrees F.
Temperatures as high as 90-95 degrees F for short periods will cause no harm, as long as proper
humidity and air circulation are maintained.
THINGS TO CONSIDER: In the world of the orchid, temperature, light and humidity work in conjunction with
one another. Unless a harmonious relationship is achieved between them, optimum growth is not
possible. In instances of low humidity, high temperatures can be dangerous; in the case of too much
atmospheric moisture, the effects of low temperatures can be over-emphasized. A widely held
misconception is that all tropical orchids need extremely high temperatures to survive. This is not
altogether true, and to subject them to such treatment can be disastrous. In the very early days of orchid
cultivation, many failures were due to growing orchids in the excessive temperatures of a "stove" house
