🌿 Paphiopedilum rothschildianum – Cultivation Guide

Also known as Rothschild’s Slipper Orchid, this is one of the most exotic and sought-after Paphiopedilums, native to Mount Kinabalu in Borneo. It is a terrestrial/lithophytic species and requires specific care to thrive.

🔍 Basic Info

• Habitat: Found in shady, limestone-rich mountain slopes (600–1200m elevation).

• Type: Terrestrial or lithophytic orchid (grows on rocks or ground).

• Status: Protected under CITES Appendix I (cannot be traded internationally without permits).

🌤️ Light Requirements

• Bright, filtered light is ideal. Avoid direct harsh sunlight (especially mid-day).

• Mimic the dappled light of a forest edge or rocky slope under trees.

🌡️ Temperature

• Day: 20–28°C (68–82°F)

• Night: 15–18°C (59–65°F)

• Key tip: A slight drop in night temperature is important to trigger blooming.

🪴 Potting Mix / Media

Use a well-draining, airy mix such as:

• Medium orchid bark

• Perlite

• Charcoal

• Crushed limestone (optional)

• Sphagnum moss (in moderation)

Avoid soggy or dense media — roots rot easily.

💧 Watering

• Water regularly when the medium begins to dry out (don’t let it dry completely).

• Avoid watering into the crown to prevent rot.

• Flush the pot occasionally to remove salt build-up.

• Use distilled, rain, or low-mineral water if possible.

🌬️ Humidity & Airflow

• Needs moderate to high humidity (50–70% or more).

• Ensure good air circulation to avoid fungal/bacterial infections.

• Do not mist heavily into the crown — it can cause rot.

🌿 Fertilizing

• Use a balanced orchid fertilizer (e.g., 20-20-20) at ¼ to ½ strength.

• Apply every 2–3 weeks during active growth.

• Flush the pot with clean water between fertilizing to avoid salt buildup.

🌱 Repotting

• Repot every 1–2 years, or when the medium breaks down.

• Best done after flowering or during active root growth.

• When dividing, ensure at least 3–4 growths per division — they’re slow to recover.
