Growing orchids successfully depends on the type of climate the original is native. Reproducing the conditions in which the plant is used in its natural state is crucial to ensure success. However, hybrids are more adaptable than their parents and will tolerate conditions that differ from their parents.
Orchids adapt to one of three zones or temperature bands, relative to where they grow, remember that whilst an orchid may come from a warm country, it may well grow at a high elevation and needs a temperature lower than that which would normally associate with that part of the world.
Temperature Zones are referred to as Cool, Intermediate, and Warm.
Some indication as to the temperature zone of an orchid may be garnered from the leaves - cool growing plants have thin leaves – warmer loving orchids have thick fleshy leaves - of course, there’s exceptions to this rule, so be wary.
Providing a climate of heat and cold is not enough, sunlight that falls onto the plant must also be considered. Generally, most orchids need shade from direct sunlight and good air circulation, just as any other life form.
Too much light sunburns the leaves to a yellow or dark red, not enough light results in dark green foliage and no flowers.
At least 60% shading will be required in the spring and summer and possibly even up to autumn if the weather is clear and warm.
