🌱 How to Care for Lady Slipper Orchid to Prevent Salt Buildup?

💧 How to Water

Water every 5 days, keeping the growing medium consistently moist but never soggy. Paphiopedilums lack pseudobulbs for water storage, so never allow them to dry out completely. Use tepid, low-mineral water if possible, and avoid getting water in the crown.

☀️ Lighting

Provide low to medium indirect light (1,000–2,000 lux). East or north-facing windows are ideal. Avoid direct sunlight, which will scorch the leaves. Under artificial lighting, place the light source 30–50 cm above the plant.

🪴 Ideal Soil

Use a fine to medium-grade orchid bark mix with added perlite and sphagnum moss for good drainage and moisture retention. Avoid heavy potting soil. For limestone-loving species, add small pieces of calcite or oyster shell to the medium.
