Oncidium trinasutum

Oncidium trinasutum is a tropical epiphytic orchid with an elegant, rhythmic growth habit and strong appeal for collectors of botanical Oncidium species. As the plant develops successive pseudobulbs, it can become a graceful and rewarding specimen in a well-aerated orchid collection.

Care Guide

• Light: Provide medium to bright filtered light while protecting the foliage from intense midday sun.
• Water: Water regularly while new growth and roots are active, allowing the medium to approach light dryness between waterings. Reduce frequency slightly after growth matures, without imposing a prolonged hard dry rest.
• Humidity: Maintain moderate to high humidity with steady air movement.
• Temperature: Grow in intermediate to warm conditions and avoid cold drafts or sudden temperature changes.
• Growing medium: Use a fresh, airy, fast-draining orchid mix that provides moisture without remaining stagnant around the roots.

With filtered light, attentive wet-dry cycles, warmth, humidity, and excellent airflow, Oncidium trinasutum can mature into an elegant tropical orchid specimen.
