Growing Orchids Is So Easy!
I had always believed that to grow orchids would be exceedingly difficult… tender, delicate and temperamental… and so expensive as to be entirely out of reach of the average person. But I have learned that none of these things are true. Orchids are within the means of any of us. There are reasonably priced plants as well as expensive ones, and because the plants remain handsome and increase in size from year to year they are an investment that brings thrilling dividends. This article is about orchid flower gardening made easy.
As for their reputed delicacy, the fact is orchids are remarkably tough and hardy. Indeed. they are freer from disease than any other plant I can think of. The
chief requirement to grow orchids is to learn the conditions under which they thrive in their native haunts and to approach those conditions as closely as possible in the home or greenhouse.
Perhaps the most important condition is proper light. Orchids, like African violets, want light but not glaring sun, in other words, filtered sunlight. Keep in mind that their native habitat is jungle "rain forests," where dense tropical vegetation allows only filtered sunlight to penetrate. Try growing an orchid plant next to your African violet in a window with a north or east exposure and watch it grow! But if you must use a window where the sunlight is too strong filter the sun with Venetian blinds or place the plant so that it receives maximum light but not direct sun.
In the greenhouse, the glare of full sun can be cut by the use of roller blinds or by painting shading on the outside of the glass, especially on south and west sides. I simply use a light coat of white enamel paint, then stipple it with a sponge.
Second only in importance to light is humidity. In tropical jungles, the air is very humid, so it follows that moisture in the air is a necessity. The why of this is readily seen. Orchids are epiphytes, usually growing upon logs or stumps (epi means above or on, phite means plant). Their roots are mostly aerial, and they take their nourishment mainly from the moisture in the air (possibly also from minerals in the decaying humus with which their roots come in contact, although they are not parasites, as is often thought).

In the greenhouse, humidity is achieved by hosing the floor and benches in the morning, at noon and in midafternoon. As this moisture evaporates into the air, it creates the needed humidity. In my own greenhouse, I have a small automatic humidity system, geared to an adjustable temperature dial, which throws a fine mist spray under the benches when the temperature reaches a certain point. This is a tremendous help, because I am away all day and can’t do the sprinkling needed in hot dry weather. More sprinkling, of course, is needed on hot, dry days than on dull, cloudy ones.
Another humidity aid in the greenhouse is to place pans of water on the floor, particularly in front of or on top of the heater. I keep a pan of water directly in front of my electric heater, and the amount of evaporation from this pan is surprising.
If you grow orchids in the home, you can achieve humidity by placing the orchid pot in a saucer of gravel and keeping the gravel moist. But do not allow the water to touch the pot, for orchids must not be set in water or allowed to become soggy. Good drainage is essential. Pot watering of orchid plants is needed only about once a week.
