Light is a key factor in growing healthy orchids. Direct sunlight may cause plants to burn, and too little light will prevent plants from flowering. An ideal location is behind curtains or window blinds. Leaf color is a good indicator of the amount of light a plant is receiving. Orchids should have bright green, healthy leaves. Dark green leaves indicate that a plant is getting insufficient light, and yellowish-green or red leaves indicate that a plant is getting too much light. If you suspect a plant is exposed to too much light, feel the leaves. If they feel noticeably warmer than the surrounding air, move the plant to a location with less intense brightness.

 In the wild, gentle continual breezes along the leafy canopy of the rain forest are vital for the survival of orchids and other air plants. Air movement acts as preventive medicine for orchids. It helps evaporate stagnant water, trapped during watering, where fungi and bacteria breed. Without ventilation or fresh circulating air, orchids eventually die from rot, lack of a continual carbon dioxide source, or infection. Ventilation also helps orchids tolerate intense light without getting burnt leaves.  You can easily improve air movement in your home so orchids grow happily. During the summer, when temperatures are high, open windows to allow fresh air to come inside. And when wintertime comes, you can use an ordinary oscillating fan to mimic the gentle breezes in the leafy canopy of a tropical forest. It is important to occasionally change the direction of the airflow so the area does not dry out.

Always water your orchid early in the day so that your orchids dry out by nighttime. The proper frequency of watering will depend on the climatic conditions where you live. In general, water once a week during the winter and twice a week when the weather turns warm and dry. The size of your orchid container also helps determine how often you need to water, regardless of climate conditions. Typically, a 6-inch pot needs water every 7 days and a 4-inch pot needs water every 5 to 6 days.  The type of potting medium being used can also affect your plant's water requirements. Bark has a tendency to dry out more rapidly than sphagnum moss, for instance. It is important to remember, however, that even when the surface of your pot is dry, the root area may remain moist. Poke your finger or a regular wooden pencil an inch into the pot; if it feels moist to the touch or if the pencil looks moist, do not add additional water. The potting medium should always be damp, but not soggy—neither should it be allowed to get extremely dry.
The quality of water used, whether for spraying or watering, is of great importance. Since tap water has often been chemically treated, generally with chlorine, it should be used with caution. The best water for orchids is undoubtedly rainwater. Rainwater, as it passes through the air, dissolves and absorbs many substances such as dust, pollen and other organic matter. This enriched rainwater contributes to the nourishment of the plant.

You can help your orchid to grow faster and bloom sooner by feeding it the right fertilizers. Look for products that contain nitrogen (N), phosphorus (P), and potassium (K), along with trace elements such as iron.  Potassium (K) is mainly responsible for the control of flower, and fruit development. Phosphorous (P) for flower production, and Nitrogen (N) for healthy vegetative growth. The amount of feeding depends on the plant concerned, the time of year and general health of the plant.
