Orchids | Cleisostoma Arietinum

Here’s your updated version — rewritten specifically for Cleisostoma arietinum, reflecting its correct origin and care profile (slightly different from C. fuerstenberianum) while keeping your same professional tone and format:

Botanical name: Cleisostoma arietinum

Common name: No widely recognized common name; generally referred to by its botanical name.

Kingdom: Plantae

Family: Orchidaceae

Genus: Cleisostoma

Origin: Native to tropical regions of India, Myanmar, Thailand, Laos, and Vietnam, typically growing as a warm-growing epiphyte in humid, lowland to mid-elevation forests.

Light:

Cleisostoma arietinum thrives in bright, filtered light conditions similar to those found beneath a forest canopy. An east or southeast window with gentle morning sun is ideal. Protect from intense midday rays, which can scorch the leaves. Artificial grow lights can supplement natural light if necessary, aiming for 10–12 hours of brightness daily.

Water:

This species enjoys consistent moisture but excellent air circulation around the roots. Water 2–3 times per week in the growing season (spring through early autumn), allowing roots to dry slightly between waterings. In winter, reduce to once weekly or when roots turn silvery white. Mist daily in drier climates or when humidity falls below 50%. Avoid letting the roots remain soggy.

Fertilizer:

Feed with a balanced orchid fertilizer (20-20-20) at half strength every 2 weeks during active growth. Alternate occasionally with a high-phosphorus formula to promote flowering. Reduce feeding to monthly or pause entirely during cooler months when growth slows. Flush with plain water monthly to prevent salt buildup.

Additional Notes:

• Best grown mounted or in an open-bark orchid mix to encourage air around the roots.
• Prefers warm temperatures (18–30 °C / 65–85 °F).
• Maintain moderate to high humidity (60–80%) for optimal health.
