💧 How to Water

Water roughly once a week by soaking the bark medium thoroughly, then let it approach dryness before watering again; never let water sit in the crown or the pot.

☀️ Lighting

Place on an east- or west-facing windowsill for bright, indirect light; direct midday sun will scorch the leaves, while leaves that stay dark green signal too little light.

Pot in a coarse, well-draining bark-based orchid mix, never garden soil or standard potting compost, and repot every one to two years as the bark breaks down.
