🌱 How to Care for Hooded Orchid to Prevent Scale Insects?

💧 How to Water

Water every 5–7 days during active growth, allowing the medium to partially dry between waterings. In winter (December–February), reduce to occasional misting every 10–14 days — do not keep the medium wet. Resume regular watering once new growth or flower buds appear in late winter.

☀️ Lighting

Place in bright, filtered light (10,000–25,000 lux) near an east or south-facing window. During the leafless winter rest period, increase light exposure significantly to stimulate flowering. Avoid intense midday direct sun in summer which can scorch pseudobulbs.

🪴 Ideal Soil

Use a very well-draining epiphytic medium such as chunky bark, coconut husk chips, charcoal and brick pieces. Mounting on cork bark or tree fern plaques is ideal, allowing excellent drainage and air circulation around roots. Never allow the medium to stay soggy.
