Light

Sufficient light is important for healthy growth and flower production. Bright light, no direct sun. In the home, an east, west or shaded south window. In a greenhouse, about 30 percent full sun. Under lights, four 40-watt fluorescent tubes and two 40-watt incandescent bulbs directly over plants.

Foliage should be naturally semi-erect and firm, not drooping. Dark green, limp foliage indicates too little light.

Temperature

Mature plants need a 15 to 20° F difference between night and day. Provide nights of 55 to 60° F; days of 70 to 85° F. Seedlings need temperatures 5 to 10 degrees higher than mature plants.

Water

Mature plants should never dry out between waterings. Seedlings need even more constant attention to moisture.

Humidity

Paphiopedilums need 60 to 70 percent. In the home, 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 potting medium has little. Paphiopedilums will grow and flower with less fertilizer than most orchids.

The exact fertilizer you use will depend on the mix in which your plant is growing. A good general rule is to use a balanced fertilizer (10-10-10, 12-12-12 or similar ratio) "weakly, weekly". That is, fertilize every week at one quarter of the recommended dilution.

Potting

Should be done every one to two years before the mix breaks down too far. Can be done almost any time of year, using a well-drained but water-retentive mix.
