🌱 How to Care for Blue Vanda Orchid to Prevent Mealybugs?

💧 How to Water

Water thoroughly every 4 days during the growing season, ensuring roots dry slightly between sessions. In winter, reduce watering drastically — mist lightly every 2 weeks. Never allow roots to sit in standing water. Morning watering is ideal to allow foliage to dry before evening.

☀️ Lighting

Provide very bright filtered light — 20,000 to 40,000 lux. A south-facing window with a sheer curtain or a greenhouse setting is ideal. Avoid harsh midday direct sun in summer which can scorch leaves. Pale yellow-green leaves signal too much light; dark green leaves indicate insufficient light.

🪴 Ideal Soil

Grow in a coarse, fast-draining orchid medium such as fir bark, tree fern fibre, or charcoal chunks. Slatted baskets or hanging pots work best as they allow superior aeration and natural root exposure. Avoid fine potting mixes that retain moisture around the roots.
