Catasetum macroglossum

Catasetum macroglossum is a striking deciduous orchid species named for its distinctive, elongated lip. Like others in the genus, it goes through a dramatic seasonal cycle, producing vigorous new growth followed by a dormant resting period, making it a fascinating choice for growers who enjoy tracking its unique rhythm.

Care Guide

• Light: Bright light, including some direct morning sun, during active growth; strong light supports vigorous pseudobulb development.
• Water: Water generously during active growth, but reduce watering sharply once leaves drop and the plant enters dormancy, keeping it nearly dry until new growth appears.
• Temperature: Prefers warm conditions between 65-85°F (18-29°C) during growth; cooler, drier conditions are fine during dormancy.
• Humidity: Thrives with humidity above 50% during active growth; less critical during the dormant resting period.
• Potting Mix: Use a well-draining orchid mix, such as bark and perlite, that allows excess water to escape quickly.
• Fertilizer: Feed regularly with a balanced orchid fertilizer during active growth, then stop completely during dormancy.

By following its natural growth and rest cycle, Catasetum macroglossum rewards attentive growers with its unusual, distinctive blooms, a fascinating addition to any orchid collection.
