Pleurothallis tricarinata is a small-sized, caespitose (clump-forming) epiphytic species found in wet montane forests across a wide range of South America. It is a adaptable species, naturally categorized as "hot to cool growing."
-
Light: Moderate, filtered light is ideal. Protect it from direct, harsh sun, which can easily scorch the thin leaves. Light conditions typical for a Phalaenopsis or brighter are suitable.
-
Temperature: Intermediate to Cool. Daytime temperatures should range from 65-78°F (18-26°C). Consistent night temperatures of 50-60°F (10-16°C) are required to ensure flowering.
-
Humidity: High humidity is essential, ideally maintained between 70% and 90%. Excellent air movement is critical to prevent rot and spotting.
-
Watering: It requires consistent moisture throughout the year. Water frequently and do not allow the root system to become completely dry. It is often grown mounted or in fine media that retains moisture while allowing rapid drainage.
Additional Notes
The plant blooms on an erect, many-flowered raceme up to 6" (15 cm) long, often longer than the leaf. The small flowers are characterized by compressed, fleshy sepals with distinct keels (carinae), which gives the species its common name: The Three Keeled Pleurothallis.
