🌱 How to Care for Philippine Ground Orchid to Prevent Anthracnose?

💧 How to Water

Water every 3-5 days, allowing the top layer of soil to dry slightly before rewatering. In hot or dry weather, increase watering frequency. Avoid waterlogging — root rot is the most common killer of ground orchids.

☀️ Lighting

Place in bright indirect light or partial sun — ideally receiving 4-6 hours of morning sun. Avoid harsh midday direct sun which can scorch the pleated leaves. Indoors, a bright east or west-facing window is ideal.

🪴 Ideal Soil

Use a rich, well-draining loamy mix. A blend of loam, perlite, and coarse bark or peat works well. Slightly acidic pH between 5.5 and 6.5 is preferred. Good drainage is essential to prevent root rot.
