🌱 How to Care for Small Spider-orchid to Prevent Phytophthora?
💧 How to Water
Water moderately only during the active growth phase (autumn to spring), keeping the substrate slightly moist but never waterlogged. Suspend watering completely when the leaf withers and the plant enters summer dormancy—the tuber must remain dry to prevent rot.
☀️ Lighting
Prefer protected partial shade with about 50% light, mimicking the open forest and woodland understory where the species naturally occurs. Avoid full, direct sun.
🪴 Ideal Soil
Use a well-drained substrate with a good proportion of coarse sand and slow-decomposing organic matter (e.g., half native potting mix + half sand). The soil should drain quickly but retain some moisture without becoming waterlogged.
