Everything it needs
9 essentials at a glance
Watering
Psychopsis papilio prefers to be watered thoroughly but allowed to dry out slightly between waterings.
During the growing season (spring and summer), water every 7-10 days, while in the dormant season (fall and winter), reduce watering to every 2-3 weeks. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause shriveling pseudobulbs.
Light
This orchid thrives in bright, indirect light, ideally receiving around 10-12 hours of filtered sunlight daily.
Avoid direct sunlight, which can scorch the leaves. A location near an east-facing window is often ideal, as it provides gentle morning light.
Soil
Psychopsis papilio requires a well-draining orchid mix, typically composed of bark, perlite, and sphagnum moss.
The ideal pH range is between 5.5 to 6.5. Ensure the pot has adequate drainage holes to prevent water accumulation.
Humidity
This orchid prefers high humidity levels of 50-70%.
To increase humidity, consider using a humidity tray filled with water and pebbles or misting the plant regularly. Signs of low humidity include brown leaf tips and wilting.
Temperature
Ideal temperatures for Psychopsis papilio range from 65-80°F (18-27°C) during the day and 55-65°F (13-18°C) at night.
It is best suited for USDA hardiness zones 10-12, as it cannot tolerate frost.
Fertilizing
Use a balanced orchid fertilizer with an NPK ratio of 30-10-10, diluted to half strength.
Fertilize every 2-4 weeks during the growing season and reduce to once every 6-8 weeks in the dormant season. Signs of nutrient deficiency include stunted growth and yellowing leaves.
Pruning
Prune spent flower spikes back to the base after blooming to encourage new growth.
Use sterilized scissors to prevent disease. Regularly check for dead or damaged leaves and remove them to maintain plant health.
Repotting
Repot every 1-2 years or when the potting medium breaks down.
Signs it needs repotting include roots growing out of the pot and poor drainage. Choose a pot that is 1-2 inches larger in diameter, and follow up with fresh orchid mix.
Propagation
Propagation is typically done through division of mature plants.
Best timing is in spring after blooming. Carefully separate the pseudobulbs, ensuring each division has roots and at least one leaf. Pot them in a suitable orchid mix and water lightly until established.

Fall
In fall, gradually reduce watering as the plant enters dormancy. Continue fertilizing until blooming stops, then switch to a less frequent schedule.
Winter
In winter, water less frequently, allowing the potting medium to dry out more between waterings. Keep the plant in a warm location, avoiding cold drafts.
