Many people think the orchid plant cannot be grown indoors. This misconception is due to the living conditions of the plant in its natural habitat. When grown in the wild, the orchid plant often forms a symbiotic relationship with other plants in order to get the nutrients that it needs. This relationship can be simulated inside the home in order to grow the plant and to get it to bloom.
The orchid plant, like most other plants, must live in the proper conditions in order for it to bloom. Many people do not understand the unique living conditions for the orchid plant and fail to produce the conditions necessary for it to bloom. Becoming familiar with what the plant needs will improve the chances for blossoms.
The three major conditions that must be controlled in order for the orchid plant to bloom are water, light, and temperature. These three are much different from other common plants. The orchid plant receives moisture through its roots like all other plants. What is different is that the orchid prefers to absorb moisture from the air rather than from the soil. Avoid planting the orchid in potting soil, because it does not like to be in standing water. Instead pot the orchid in tree bark or a similar loose substance.
The orchid thrives in bright, indirect sunlight. Place the plant close to a south facing window. If the plant is too far from the light it will not bloom. If you notice new growths getting smaller and the leaves getting narrower then the plant is not close enough to the light source to bloom. In this case it should be moved closer.
In its natural habitat, the orchid experiences a dramatic temperature change between day and night. You can simulate this change in your home by setting the thermostat ten degrees lower at night time. This temperature change is vital for the plant to bloom. The orchid will continue to grow without this change, but it will not bloom.
