🌱 How to Care for Snow Queen Orchid to Prevent Caterpillars?

💧 How to Water

Water once a week during active growth (spring to summer), allowing the medium to approach dryness before re-watering. In autumn and winter, reduce watering to once every 2-3 weeks. Always use tepid water and water from the base to avoid wetting pseudobulbs.

☀️ Lighting

Provide bright indirect light of 15,000-40,000 lux. Avoid direct midday summer sun which can scorch leaves. In winter, maximize light exposure to help trigger flowering. East or west-facing windowsills work well; supplement with grow lights if needed.

🪴 Ideal Soil

Use a well-draining orchid medium: medium-grade fir bark or pine bark mixed with perlite, sphagnum moss, and a small amount of horticultural charcoal. Avoid heavy, water-retentive soils. Slightly acidic pH of 5.5-6.5 is ideal.
