🌱 How to Care for Pink Rock Orchid to Prevent Thrips?

💧 How to Water

Water thoroughly once a week in spring and summer when the medium is nearly dry. In autumn and winter, reduce to every 2–3 weeks to allow dormancy. Never let roots sit in standing water — root rot is a key risk with overwatering.

☀️ Lighting

Provide bright, filtered light — ideally 15,000–25,000 lux. A red tinge to leaves indicates ideal light levels; dark green leaves signal insufficient light. Morning sun or east-facing exposure is ideal. Avoid harsh midday direct sun.

🪴 Ideal Soil

Use a free-draining orchid medium such as fine pine bark, sphagnum moss, or a blend of both. Slightly acidic pH of 5.5–6.0 is ideal. Avoid heavy potting mixes that retain moisture.
