🌱 How to Care for Cowhorn orchid to Prevent Grey Mould?
💧 How to Water
Water generously during the growth phase (spring to summer), allowing the substrate surface to dry slightly between waterings. Drastically reduce watering after the leaves drop, keeping the pseudobulbs almost dry until new growth appears.
☀️ Lighting
Provide bright light, preferably full morning sun or intense filtered light throughout the day; low light reduces flowering and weakens the pseudobulbs.
🪴 Ideal Soil
Use an open, fast-draining substrate based on pine bark, perlite, and tree fern fiber, with a slightly acidic to neutral pH; avoid substrates that retain excessive moisture.
