Care Tips for Begonia U192 (Martin's Mystery):

• Light: Prefers medium to bright, indirect light. Direct harsh sunlight may scorch leaves; too little light may reduce the metallic / pinkish sheen.

• Water & Humidity: Keep substrate moist but well-draining. Water when the top ~2–3 cm of soil is dry; avoid letting water stand on leaves. Moderate watering + good humidity support healthy growth.

• Soil/Container: Use a well-draining potting mix; a loose, airy mix is ideal. As a small/compact plant, a small pot or terrarium works well.

• Environment: Prefers indoor conditions or a humid microclimate (e.g. terrarium, humid room). In dry indoor air, consider occasional misting or placing near a humidity tray.

• Maintenance: Keep an eye on leggy stems — sometimes stems can become long and may need pruning or staking. Broken stems can often be propagated for recovery.
