- Water
- Keep the mix evenly moist but never soggy; do not leave the pot standing in water. General guidance for the genus
- Humidity
- Moderate, about 40–50%; a tray of damp gravel helps, with steady air movement. General guidance for the genus
- Temperature
- Nights about 13–22 °C (55–72 °F), days 21–29 °C (70–85 °F); mottled-leaf and multi-flowered types prefer the warmer end, plain green-leaved types the cooler end. General guidance for the genus
- Soil
- Fine to medium fir bark with perlite, sand or sphagnum; limestone-dwelling species appreciate added limestone chips or oyster shell. General guidance for the genus
