Water

The number one cause of death in houseplants is overwatering. Orchids are no exception. Most orchids prefer the growing media to dry
between waterings. There are several methods to determine when a plant needs watering. Insert your finger about 1 inch into the soil near the center of the container.

If the soil feels dry, the plant needs water; if it is wet, wait. You can also pick up the pots to compare the weight of a dry pot versus a wet pot. The pot will be lighter when it is dry. It is better to soak the plant thoroughly and occasionally than to water frequently with small amounts of water. To thoroughly water an orchid, place it in a sink and add lukewarm water until the water runs freely from the bottom of the pot. Avoid using cold water (below 50F), since this can damage roots and can kill root hairs. About twice a year, put your plants in the shower, and run warm water over them for several minutes to clean the dust off the foliage.

Humidity

Orchids love humid conditions. They prefer a range of 50-70 percent relative humidity. There are several ways to increase the humidity in the orchid’s environment. The simplest method is to place several plants close together to increase the humidity of the air surrounding the
orchids. Plants can also be placed on trays containing a layer of pebbles or small gravel.

Fill the tray with just enough water to fill the spaces between the gravel particles. The water in the gravel will increase the humidity. Never allow orchids to sit directly in water, since this can cause root disease. You can also increase the humidity by placing the plants in a bathroom window, by using plastic containers instead of clay pots, or you can purchase a humidifier. Air conditioners and heaters dry the air, so avoid placing orchids near vents or ducts.

Air Circulation

Air movement is also important to grow orchids successfully. Air movement helps to decrease the incidence of fungus diseases and bacteria, and it aids in supplying carbon dioxide, which is necessary for the plant to photosynthesize. Most orchids placed in a windowsill will receive adequate air circulation.
