Everything it needs
9 essentials at a glance
Watering
Bulbophyllum medusae prefers to be kept consistently moist but not soggy.
Water every 5-7 days during the growing season (spring and summer), allowing the top inch of the medium to dry out between waterings. In fall and winter, reduce watering to every 10-14 days. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause shriveling and drooping leaves.
Light
This orchid thrives in bright, indirect light, ideally receiving 4-6 hours of filtered sunlight daily.
Avoid direct sun exposure, which can scorch the leaves. A north or east-facing window is ideal, but it can tolerate partial shade as well.
Soil
Bulbophyllum medusae prefers a well-draining orchid mix, typically composed of bark, perlite, and sphagnum moss.
The ideal pH range is between 5.5 and 6.5. Ensure that the potting medium allows for good air circulation and drainage to prevent root rot.
Humidity
This plant enjoys high humidity levels, ideally between 50-70%.
To increase humidity, consider using a humidity tray, grouping plants together, or using a humidifier. Signs of low humidity include browning leaf tips and wilting.
Temperature
The ideal temperature range for Bulbophyllum medusae is 65-85°F (18-29°C) during the day and not dropping below 60°F (15°C) at night.
It thrives in USDA hardiness zones 10-12, showing good tolerance to warm conditions but can suffer in extreme cold.
Fertilizing
Use a balanced orchid fertilizer with an NPK ratio of 30-10-10, diluted to half strength.
Fertilize every 4-6 weeks during the growing season and reduce to every 8-10 weeks in fall and winter. Signs of nutrient deficiency include stunted growth and yellowing leaves.
Pruning
Pruning is minimal for Bulbophyllum medusae.
Remove any dead or yellowing leaves to promote air circulation and prevent disease. Use sterilized scissors to avoid introducing pathogens. Deadheading is not necessary as this orchid blooms from the same pseudobulbs each year.
Repotting
Repot every 1-2 years or when the medium breaks down.
Signs that it needs repotting include roots growing out of the pot or poor drainage. Choose a pot that is 1-2 inches larger in diameter than the current one. Gently remove the plant, trim any dead roots, and replant in fresh orchid mix.
Propagation
Propagation can be achieved through division.
The best time to divide is in spring when the plant is actively growing. Carefully remove the plant from its pot, separate the rhizomes ensuring each division has roots and at least one pseudobulb, and replant in fresh orchid mix. Water lightly after repotting to avoid shock.
When it's unhappy
Yellow leaves
Why it happens
Over-watering or insufficient light.
How to fix it

Browning leaf tips
Why it happens
Low humidity levels.
How to fix it
Increase humidity through trays of water, grouping plants, or using a humidifier.
Shriveling leaves
Why it happens
Under-watering.
How to fix it
Increase watering frequency and ensure the medium retains moisture without being soggy.
Pest infestations (e.g., aphids, spider mites)
Why it happens
Low humidity and poor air circulation.
How to fix it
Increase humidity, improve air circulation, and treat with insecticidal soap or neem oil.
Care through the year
Spring
Increase watering as the plant begins to grow actively. Fertilize every 4-6 weeks with a balanced orchid fertilizer.
Summer
Maintain consistent moisture and humidity levels. Provide bright, indirect light and continue fertilizing every 4-6 weeks.
Fall
Reduce watering frequency as growth slows. Fertilize every 8-10 weeks and monitor humidity levels as temperatures drop.
Winter
Water less frequently, allowing the medium to dry out more between waterings. Ensure the plant is kept in a warm environment with adequate humidity.
Toxicity & Safety
Bulbophyllum medusae is non-toxic to pets and children. However, ingestion of any plant material can cause mild gastrointestinal upset. It's best to keep all plants out of reach of small children and pets.
