🌱 How to Care for Orange Cattleya to Prevent Thrips?

💧 How to Water

Water deeply about once a week, letting the bark-based mix dry out between waterings; the pseudobulbs store water, so overwatering is a bigger risk than underwatering.

☀️ Lighting

Provide bright, filtered light such as an east-facing or lightly shaded south-facing window; leaves should be light green, not dark green (too little light) or yellowish-red (too much).

🪴 Ideal Soil

Pot in a coarse, fast-draining bark-based orchid mix (bark, perlite, charcoal) or mount on a slab; never use regular potting soil.
