Care Guide
Watering
Keep the soil consistently moist. During the growing season, water when the surface soil feels barely dry. Ensure the pot has drainage to prevent root rot.
Light
Provide bright, indirect light to maintain the vibrant bronze color of new fronds. Direct afternoon sun should be avoided as it will scorch the leaves.
Humidity and Temperature
Aim for humidity levels above 50%. This plant enjoys stable indoor temperatures between 60°F and 75°F. Avoid placement near drafty windows or heating vents.
Seasonal Care
During winter, the plant enters a dormant phase. Reduce watering and stop fertilizing until new growth appears in the spring.
Common Issues
Brown edges usually indicate low humidity or underwatering. Pale, washed-out fronds may be a sign of too much direct light.
