4 Temperatures for growing orchids
In nature orchids inhabit various habitats,
from low land rain forests to mountain slopes, to swampy areas.
Therefore we can expect some orchids to need the warm
conditions of a tropical rain forest, others to need the cool
conditions of a slope on the foothills of mountains and yet
others to have needs somewhere in between.
Orchids are classified in 3 temperature
groups: orchids that require cool temperatures, other that
require intermediate temperatures or others that need warm
temperatures.
Here are the temperature ranges for the
three groups, and please don’t hold me to the degree, as
you’ll most probably see different ranges somewhere else:
Please notice the difference between day
time and night time temperatures. In the natural world it
is, most of the time, warmer in the day and cooler at night.
So when you grow your orchids keep this in
mind, especially if you grow them in a bathroom which many of
us, in the winter, tend to warm in the morning, then let it
cool during the day, then warm it again at night.
But remember these temperatures are ideal ranges and, within reason, you
can acclimate your orchids to grow pretty well a few degrees
outside of these ranges.
Your warm growing orchids will not die if
they are subjected to day time temperatures of 90 degrees
for a few days or to 55 degrees for a few nights. But at
these temperature levels your orchids will stop growing and will become more susceptible to insects and diseases, because there will be under stress.
