Watering should be thorough, and plants should dry at least halfway through the pot before watering again. This may be every 2 to 10 days depending on weather, pot size and material, type of orchid and type of potting medium. Most of these orchids require less humidity than some other orchids. In the home, placing the plants on trays above moist pebbles is ideal. Misting the plants in the morning may help increase humidity but is usually not recommended for fleshy-leaved types.
Most greenhouses have adequate humidity.
If skies are cloudy, applications once a month are sufficient. Spread the roots over a cone of potting medium and fill in around the roots. Firm the medium well around the roots by applying pressure. Keep humidity high and the pot dry until new roots form. A vitamin B1 compound may help establish newly potted plants.
