Neobathiea keraudrenae

Neobathiea keraudrenae is a rare and elegant monopodial epiphytic orchid native to eastern Madagascar, meaning it grows upward from a single stem and attaches to trees or other supports.

Care Tips:

Mounting & Medium

• Best suited for mounting on bark slabs or tree-fern fiber with a cushioning layer of coconut fiber or sphagnum to anchor roots until attachment.

• Alternatively, a well-draining pot mix of coarse pine bark, charcoal, and pumice or osmunda fiber and sphagnum is recommended.

Light & Temperature

• Light: Bright, filtered light — avoid direct midday sun. In summer, provide ~50% shade; in autumn, increase light to promote growth and flowering.

• Temperature:

  • Summer: Day 18–25 °C, Night 15–18 °C. Tolerates above 25 °C if humidity stays high (≥70%).

  • Winter (cooler): Day 18–20 °C, Night 12–15 °C. Avoid chilling below ~5–8 °C to prevent damage.

Humidity, Watering & Airflow

• Maintain relative humidity around 60–70% during active growth; reduce watering slightly during winter but do not allow dehydration.

• Watering regime:

  • Spring/Summer: Water freely in the morning; use sprinklers or misting, but stop by midday to allow drying to prevent rot.

  • Winter: Cut back watering, with occasional morning misting.

• Ensure good air circulation year-round to discourage rot and aid drying.

Fertilization

• Apply diluted balanced fertilizer during growth and flowering seasons.

• Allow a rest period (e.g., December–February) with reduced fertilization.
