Care Guide

Light

• Preference: Prefers bright, indirect light but can tolerate lower light conditions. Avoid direct sunlight, as it can scorch the leaves.

Water

• Moisture Needs: This plant thrives in high humidity and moist soil conditions. Water it regularly to keep the soil consistently damp but not waterlogged. Reduce watering during the cooler months.
• Humidity: High humidity levels are beneficial. Consider placing it in a bathroom if it's well-lit or using a humidifier to increase moisture in the air.

Soil

• Type: Requires a rich, well-draining potting mix. An ideal mixture would be one part peat, one part pine bark, and one part coarse sand or perlite.

Temperature

• Range: Prefers warm conditions, ideally between 18°C to 29°C (65°F to 85°F). Avoid temperatures below 15°C (59°F), as cold can severely damage the plant.

Fertilisation

• Routine: Feed with a balanced liquid fertilizer every month during the growing season (spring and summer). Reduce feeding to every other month during autumn and winter.

Pruning and Maintenance

• General Care: Prune away any yellowing or dead leaves to maintain its appearance and health. Clean dust off leaves with a damp cloth to ensure efficient photosynthesis.

Repotting

• When: Repot every 2-3 years or when the plant becomes root-bound. Use a pot only slightly larger than the previous one to prevent overwatering issues.

Pest and Diseases

• Common Issues: Watch out for pests like spider mites and mealybugs, especially in dry indoor air. Maintain high humidity and inspect the plant regularly. Use insecticidal soap or neem oil as a treatment.
