Care Instructions

• Humidity & Temperature: Maintain humidity levels between 50% and 80% with good air circulation to prevent fungal issues. Ideal daytime temperatures are 18C to 27C (65F to 80F), with slightly cooler nights being beneficial.
• Potting Media: Tolumnias prefer very open, well-draining media such as coarse bark or charcoal. They are often grown mounted on bark slabs, which replicates their natural environment and ensures excellent drainage and airflow.
• Fertilizing: Use a diluted, balanced orchid fertilizer monthly. A high-nitrogen formula (like 30-10-10) should be used during active growth, switching to a bloom-booster (10-30-20) as flower spikes form.

Light & Water Needs

• Light: They need bright, indirect light, similar to Cattleya orchids but less than full sun. East or west-facing windows are ideal, with sheer curtains used to diffuse harsh midday sun to prevent leaf scorch.
• Watering: The key is a wet/dry cycle. Water thoroughly in the morning, then allow the roots or potting medium to dry out completely before watering again. This may mean daily watering for mounted plants or every 1-2 days for potted ones, depending on your home’s conditions.

Size & Dimensions

• Mature Size: Small, compact orchid.
• Pot Size: Varies; commonly available mounted on bark slabs or in small pots.

Origin

Native to the Caribbean islands, Tolumnia orchids are accustomed to tropical and subtropical environments.
