Light

Sufficient light is important for healthy growth and flower production.

Provide very bright light, up to 80 percent of full sun in coastally moderate areas.

Leaves should be naturally erect and of a medium olive-green color. Dark green, limp foliage indicates too little light.

Temperature

Mature plants need night temperatures in the low 60s or high 50s in late summer to initiate flower spikes. Provide nights of 50 to 60° F, though temperatures into the 30s are tolerated; days of 70 to 85° F if shading, humidity and air circulation are increased.

Water

Mature plants must never dry out between waterings.

Humidity

Cymbidiums need 50 to 60 percent. In the home, while in bloom, place on trays of moistened pebbles. In a greenhouse, use a humidifier if conditions are too dry.

Fertilizer

Must be provided on a regular basis because most potting medium has little. The exact fertilizer you use will depend on the mix in which your plant is growing. A good general rule is to apply a balanced fertilizer (10-10-10, 12-12-12 or similar ratio) "weakly, weekly". That is, fertilize every week at one quarter to one half of the recommended dilution.

Potting

Best done every two to three years in the spring, immediately after flowering, in order to allow maximum time to reestablish before the next flowering season.
