Care Notes
Light
Bright, indirect light keeps the pink and cream strong. Direct sun burns leaves. Low light fades patterns toward plain green.
Water
Keep the mix evenly moist, never soggy. Water when the top inch feels dry. Distilled, filtered, or rainwater helps prevent tip burn from minerals. Use a pot with drainage holes.
Soil
A peat-based mix with perlite or orchid bark drains while holding moisture. Repot every 1-2 years in spring if roots pack the planter.
Humidity & Temperature
Aim for 60% humidity or higher with a humidifier or pebble tray. Keep temperatures around 65-80°F and away from cold drafts and heater vents.
Common Issues
Crispy edges usually mean low humidity or hard water. Drooping often means dry soil. Yellow leaves often mean overwatering or poor drainage.
